Is your AC fan not working or spinning? It's possible that it is simply not getting power or that the capacitor is dead but the condenser fan motor itself is good. In this video I show you how you can check your AC fan motor to see if it is good or bad.

@whitleyca Месяц назад

You are too good! Can't thank you enough for putting this info out there. Our fan quit working a while back. Your videos pointed me through the troubleshooting effort: capacitor tested ok and was not physically deformed. Then found quite a few dead ants in the contactor. Cleaned it out and the fan turned on as it should. Fast forward a few weeks and the fan has quit again. Will be testing it as you have shown here. Very much appreciated!

@robertfulton4829 Год назад

You just saved me about $500. The ohms were good but the motor is 17 years old and I'm told it has seized up. Capacitor was just replaced. Amazon and RU-vid to the rescue!

@KittyNoNo Год назад

How did you deduce that the fan motor had seized up? Does it not spin freely by hand? I'm curious because I think I'm in the same situation you are. After 18 years, my condenser fan stopped working. All these guides say to check the ohms, and if the readings are correct, then the fan is fine. My ohms were perfect. the fan spins freely. I took the fan motor apart to check for damage/corrosion, and it looks almost new. However, it will not come on. The compressor comes on, then shuts down due to the fan not spinning. I have all correct voltage at all connections. New capacitor. So, it has to be a bad motor, right??? lol! I appreciate these videos, and I know the content creators try to keep their tutorials as basic as possible - but I haven't heard "If the fan's ohm readings are correct, then the fan is most likely good. However, it is possible that other issues with the motor could prevent it from working." I'm just going to order a new motor, and return it if it doesn't work. I'd really like to hear how your repair goes! Good luck!

@robertfulton4829 Год назад

@@KittyNoNo our AC guy mentioned that the fan motor may become noisy i.e like a bad bearing. I didn't notice anything specifically, since we have 2 units outside and can't really hear them inside. I figured there aren't many other things that could be bad, and the capacitor was replaced the day before. I didn't take the motor apart to look for corrosion, but it seemed like a reasonable cause of failure. I didn't want to pay his fee to come back out and check it/replace the motor (which worked when he left the day before), so I found this video.

@robertfulton4829 Год назад

Mild panic, the new motor came in, and it had 2 additional wires connected in a loop, which changed the black wire to blue. In between looked like a lighting ballast. White ceramic. No where to put it, and definitely would get in the way of the fan. We zip tied it to the grate. Hope it works out! We plugged everything in, confirmed voltage. The compressor started but not the fan. We pushed the blade with a stick a little and it took off. We have cold air! We hope the repairs hold up. Thanks again!

@KittyNoNo Год назад

@@robertfulton4829 Thank you very much for taking the time to reply. I see that you've installed the new motor, and that it solved your problem. Good to hear! Hopefully, push -starting the fan was a one-time thing and it will start automatically going forward LOL I''m looking forward to cold air too! Thanks again!

@MrCeora 2 года назад

No offense, but for a young guy, you really have your stuff together. I really appreciate how you put emphasis on safety precautions. I took my grandson to a trade school open house, and as we walked out of the electrician display of graduates, there was a separate display of one particular individual. I asked what was the reason for his distinction. We were told that on the second week of his first job he had electrocuted himself by not following one of the basic rules that were taught at the class. You never know if your emphasis on safety and what is routine practice for you, could reach the right ears and save a life.

@MrCeora Год назад

@Blank Man No offense that I first assumed because of his age he wouldn't be as cautious and safe as he is. An assumption that I apologize for having is what I meant.

@MrCeora Год назад

@Blank Man The young man who electrocuted himself was relatively young and in his 30's, probably like you. Maybe subconsciously that was In the back of my mind. Who knows.

Our A/C unit has making buzzing sound all the sudden I replaced entire A/C system and unit 2years ago. It was about $6000.😢 I am so upset because #1 insist so freaking hot and #2 only 2years?? I am having issues with brand new A/c unit 🤬I called the company 3times they don't even call me back.

@fortunateson6070 5 лет назад

I subbed to your channel last year when I became a homeowner, this video fixed my A/C this morning after it broke down last night and I was still able to go to work. My capacitor wasn't shorting to ground, but it was almost too hot to touch when I removed it. I was able to push start the fan last night and set the temp down to 65 so it would run all night and we got some sleep before the repair.

@KwiK808 Год назад

Really appreciate all your videos. Very consice. My mother's unit was frooze up, so I helped her get it running again. But the tech she had apparently called came over. He simply added more refrigerate and left. Only to wake-up to a frozen unit again. Now the blower motor is not even kicking on. Hopefully it does not need replaced. God Bless & God Speed Brother.👍🏻

Thanks for SAFETY FIRST cautions, so very important in everything we do, especially when we are around electricity !! A big thank you for the detailed video on how to check the fan motor Ohms resistance. At first I changed out the Start Capacitor and motor started, but would not keep running. Then I followed your instructions for checking the motor and decided it should be replaced because of the Ohms resistance measurements and what I felt were bad bearings (way to much end play). New motor in and running great.

@jawojnicki 3 года назад

Hi Jay. My fan does not turn on by itself, but when the compressor is running and I start the fan spinning with a screwdriver it will keep spinning by the motors power. Is this pretty much a slam-dunk capacitor diagnosis? If not, what could be the issue? There is no abnormal heat nor sound coming from the fan motor when it is running

@stevebolaris1076 4 года назад

Thanks! Through your videos I have been able to isolate the fan non operation as the issue. Next up for me is to use what I learned here to check the resistance with my meter to verify that it is the fan motor that is in fact bad before spending perhaps hundreds on a new motor. The only other thing that I am unable to check is the r-22 pressure as I do not have the proper gauges for that.

Great video. My ac stopped yesterday. Replaced the capacitor today. The fan didn't start, but I nudged it and it started, and cooled for quite some time, then stopped.

Can a contractor cause a compressor to run and fan motor to not work ? I know it sounds like a capacitor but capacitor is fine and motor was replaced recently

@ranger178 29 дней назад

how much force should the motor take to turn when power is off? I think my fans bearings are worn out being 26 years old it seemed a bit hard to turn i spun it a bit and it loosened up some then worked when i manually turned on contactor

@hoonyur5973 4 года назад

I am not getting any continuity/resistance at an fan wire combination. Also, no continuity with any fan wire to ground. I have confirmed i am getting 240v to the contactor (brand new) and my capacitor specs out at the rated farad rating and not bulging at the top(replaced last summer). The fan spins freely so it’s not seized but it also won’t start when tapped with a screwdriver. I also noticed that the sealed bearing on the fan seems to be either leaking/lubed prior. As a last note, the fan motor gets hot but doesn’t spin when ac is turned on. I am really thinking the condenser fan is shot but wanted to see that if given these symptoms, has that been your experience as well..?

@Jlarroyo7 5 месяцев назад

Hey Jay! I swapped my capacitor out since my readings were 28/3 on a 35/3 capacitor. I also checked the fan wires and got 159 , 122 & 37 between the wires. The fan still won’t start until I give it a push a few times. Do you think the condenser fan motor can still be bad even though readings add up? Should the fan wire lower readings be more even?

@BlackLight_VA 5 месяцев назад

What's up Jay? I have a Trane split system heat pump and it isn't cooling like it should. I feel confident that it's the fan because it doesn't always come on when the compressor does and seems to cut off early and seize up but the resistance numbers added up exactly (41, 70 and 111) and I just changed the capacitor. Is it possible that the problem is still the fan motor or should I look elsewhere?

@ThanhVanNguyen-v6h 3 месяца назад

Thank yoi for sharing video. I have a question when i check my ac fan motor with multimeter: the brown and black is 52.7, the purple and black or purple and brown are OL. Does it mean my fan motor is bad or just the purple wire goes bad? Thank you

@davidlektzian7748 5 месяцев назад

Thank you for this helpful video and all of your other great videos. In my situation, the fan was not spinning and I used a stick to get it started. That worked temporarily. Then it stopped working and I discovered the main 240 volt fuses outside the house were blown. I replaced the capacitor and the contactor and coil. I replaced the fuses and they instantly blew. I checked the motor today and got resistances of 24.7, 57.8, and 76.4. They are a lot lower than you got in the video, but they roughly add up, so I'm thinking the fan motor is probably good (the motor is a 208/230 1/4 hp unit). The AC unit is a PH13NR048 manufactured in 2011. Any ideas on the next step? Is it time to call in a repair tech?

@jamesrockford5145 6 лет назад

Simple and to the point. If you checked continuity between the individual wires and you didn't hear the beep, that would also indicate bad motor?

@WordofAdviceTV 6 лет назад

Yes. If there is no continuity, then the winding is open and the motor needs to be replaced. Although once in a while my meter plays tricks on me.. (perhaps it was weak batteries) I check for continuity and it doesn't beep. But then I check resistance and there is resistance..

@pondersomewhat Год назад

Thanks for your videos! I've watched pretty much all of them to do with HVAC. My heat pump unit has started tripping the in-house circuit breaker instantly every time it starts up. If I disconnect the fan leads from the defrost control board so that the fan is out of the circuit, the compressor starts up just fine and the breaker doesn't trip. I tested the capacitor and it is good. I ohmed out the motor and it appears fine. I swapped in a replacement motor anyway and the same short circuit occurs. Does this mean the short is happening in the defrost board? The defrost board controls the main contactor for the compressor and a relay for the fan, but I don't see any damage to the board. It's a Trane CNT02940 defrost board, which I think is supposed drive the fan at 2 speeds. Should I be seeing 240V across the fan motor contacts when the compressor is running, because it looks more like 9 to 12 V.

@jhug1987 3 месяца назад

Thanks for the guide, but quick question. My A/C is out - condenser comes on but fan does not. I've already changed the capacitor, which led me to check the fan motor with this video. However, my ohms are adding up. I got 38, 52, and 88. What's my next move?

@earlclay7348 5 лет назад

I have an A/C system that is about 8 years old and the outside unit stopped coming on this past Sunday. I watched all of your videos, thank you BTW, but I can't seem to find the problem. I like to at least try to fix things myself but I don't know if I just wasted a day of no AC in the heat here in AZ. I tested my Compressor, I have continuity for all 3 plug ins, none of them are shorted out. My fan motor read 54.6, 35.8 and 90.3, so that looks good. My capacitor is a 45/5 Dual and read 47 and 5. I'm not sure what else I can do to check what's going on. I can press the little plastic button and the whole system turns on, but it does seem to be running a little slow. Oh, I also have 240 volts going to the unit. What else could be wrong ? Thanks for the help

@WordofAdviceTV 5 лет назад

Hi Earl! Sorry to hear that the AC quitting on you. Have you checked voltages in and out of the contactor? So 240v goes into one side and 240v should come out the other side when the little plunger gets pulled in. Also, you mentioned that you pressed on it and it came on. Does that mean the contactor plunger does not pull in on it's own? Does the coil get 24v when there is a call for cooling? If the contactor is not pulling in on its own, then I would start by figuring that out first. I have a video on 10 reasons why a contactor may not pull in if you need it.

@williamvann4305 2 года назад

Jay, thanks for your informative videos. I have an old Trane system which is still working pretty well, but the condensor fan is shutting off intermittently. I checked the resistances between the wires as you advise in this video and the sum of the 2 equal the 3rd indicating the motor is good. Is it shutting off due to internal heat protection? Would a new one do the same thing? The condensor unit is in the direct sun in the afternoon, so it gets pretty hot there when the outside temperature gets to 90 degrees or above.

@fortyampbreakerr6234 Год назад

@robertcadena8517 4 года назад

Thank,your videos are very precise and informative. I verified that my compressor is working and I've installed a new capacitor. I then checked the three wire"s you've shown on my condenser fan and get an OL reading from all of the wires. Does this mean that the fan is bad?

@wpzhang 5 лет назад

Thanks for your great videos! If the resistances are good, what other reasons can a fan motor go bad?

@WordofAdviceTV 5 лет назад

A motor can fail electrically or mechanically. A meter won't help with a mechanical problem. A seized motor for example, where the bearing is shot. If you spin it by hand and it spins hard instead of freely, then the motor is bad. You can try oiling it, that might free it up. Usually the motor would get replaced though.

@wpzhang 5 лет назад

@JF0913 6 лет назад

Yes could not get to the point. This unit unfortunately is in direct sunlight most of the day, so I expect the parts on the unit to not last as long as they should. So oddly enough it eventually got to the 71 degrees a while ago. Do you think that maybe it could be that the compressor is starting to act up. The unit is 9 years old. The suction line is cool and sweats as you show in your video.

Question - My fan motor is overheating and shutting down after running for about 20min on a Carrier Infinity condenser. I put a new fan motor on and I am certain that it is good (bench tested). I also swapped fans from my second condenser (same model runs well in that condenser) and same problem. I tried two capacitors and I even bypassed the dual run and isolated the fan on its own capacitor and still the same problem. Any thoughts on what could be going on? Transformer, PCB? Any thoughts would be helpful and thanks for the awesome tutorial!!!

What if my fan starts running only if I give it a push with a screwdriver? It does stay on once I help it. It turns real easy and it doesn't look like it's "stuck". Could that mean my capacitor is bad? (It does look like it's bulging, it's also 15 years old so I just ordered a new one, but was curious if the "fan needs help to start" is one of the symptoms of a bad capacitor).

@MrFallred Год назад

What if your condenser fan motor is over amperage? Do you have a video on that issue? Our unit was running loud outside and the air inside wasn't cooling down, and tech said over amperage was the problem and to replace condenser fan motor and that it was probably overworked this summer/older unit. If I turn AC on now the unit still works and does NOT run loud but it's still not cooling. I feel like I don't know why the motor is over amperage or what that really means, or that replacing it solves anything.

Your really helping, but theres one question, how to identify the common leads wire in condensor fan motor

@WordofAdviceTV 5 лет назад

There should be a little wiring diagram on the specs label on the motor itself. Usually it shows which wire is common there. Otherwise you can look on the condenser wiring diagram and see what color wire it is there. I also have a "how to wire a condenser fan motor" video if you need it.

@michaelsmith1124 2 года назад

What would cause a fan motor to overheat? I've replaced the capacitor with exact relpacement then when powering on, the old fan was noisy, probably the root cause of the capacitor going out on the fan side. Then I installed a new fan motor (exact replacement Fasco D934). AC would run for about 4 minutes before the fan shut off. Compressor was still running. The fan motor was extremely hot. Could I have a bad motor? Wiring problem? I'm running out of ideas. I really like your video's. Thank you, Mike of Chicago

Jay, so my capacitor is kind of new. I replaced it myself a while ago and it’s been working fine. And it’s not bulged up and I check continuity with my primitive meter. So I believe the capacitor is ok. I have continuity with my fan motor wires and the olms #’s add up. So theoretically the motor should be good, but when I try to spin the fan blade, it doesn’t spin freely. That leads me to believe that the bearings are seized or in need or lubricant. Should I bother disassembling the motor and try to lubricate the bearings, or just get a new motor? What would you do? Thanks. Mike

How long are those fan motors supposed to last? I had the motor replaced several years ago and the capacitor more recently. I also did a complete clean out of the condenser coils and the thing worked great until we had a bad rain storm, the only the compressor would run but not the condenser fan. I dont have all those fancy electronic testers like you so i just tapped various components with a stick and prayed to the appropriate entities but my problem didnt improve. I also wonder if that relay could be at fault . I used the stick on that along with some prayer and it also turned on the compressor with no fan. This problem began last august of 23. I still pray over it from time to time but to no avail. Im getting nervous with summer looming closer

Where do you change the speed on an A/C condenser fan? Mine is moving slower than it should. Would I find this wiring in the condenser or air handler?

@WordofAdviceTV 2 года назад

Usually condenser fan motors do not have adjustable speeds. Was it always like this or is this a recent development? If it is recent, then I would guess that either the capacitor is weak/dead or the motor is not getting enough voltage. (perhaps a fuse in the disconnect box is blown? Would need a multimeter to check for sure)

@earthwisdomhelps 2 года назад

@@WordofAdviceTV The maintenance person has been messing with my AC from the condenser on purpose it was working fine and in April he pulled the disconnect switch. Then I had no AC. When I put in a work order for it to be fixed, he was sent to fix it. Only after he left the temp took an hour to drop one degree, in an 800 square foot apt. Everyone else drops 4 degrees in 20 minutes how mine did before. Now it will take 4 hours to go down 4 degrees.I went out to look at my fan because I know he is doing it on purpose. My fan is slower than everyone else. Theirs are spinning fast that you can't see the blades. Mine is different. I have a witness, another neighbor looked and said my fan is slower than the others. The maintenance man did something on the condenser to change the fan from fast to slow. I am just trying to figure out what he did not he AC condenser, if he pulled a wire or move a wire how he changed the speed.

@@WordofAdviceTV Thats the word Sabotage. I called Rheem contractors and people who answered the phone said the fan being slow would cause it not cool. I'm not getting him to come back he doing it. I will have to hire someone but I don't know why I can't find out what he did to slow that fan. He did not come in my unit it's doing it on that condenser. What wires are switched and where to control the blades to go fast or slow? I know the air handler is in my apt. He is configuring it from the AC condenser that goes to my unit located outside. (Another thing when he left, he used an inferred gun showing it was coming out 8 degrees, out of the vents lower than the setting. Even thought it's 8 degrees lowering than what it shows on the thermodat, I found out that it's not going to matter due to the fan speed. Someone else told me, the old neighbor, he used to work on AC and said the ideal temp coming out of the vent is 20-25 degrees lower than wha the thermosdat says. I have an inferred gun my neighbors thermostat was on 72 and it was the temp from the vents was between 47 and 48.

Does the fan motor have to run an order for heat to work on a electrical furnace? We don't have any heat of the blower is blowing out cool air and the fan is not turning on the outside. This is the same behavior when it was below 30° and above 30°. I've checked voltage for the defrost module sensor and thermostat 24 volts all the way around.

@genericusername1365 4 месяца назад

Verified power going to unit. Replaced bad capacitor with a good capacitor, but fan still doesn't turn on. Ohm tested the three wires which come from the fan and the resistances all add up perfectly. Can the fan motor motor still be bad despite that?

@Michael_303 5 лет назад

So my AC unit has one of those Turbo 200X universal caps and a hard start kit. I'm not sure what the original cap was but the one that's in there tests at 10mfd and 175mfd. It's not bulging so I think the cap is ok. The fan doesn't spin freely and doesn't spin up with help but the fan leads tested at 27, 27 and 55 ohms. My guess is the fan motor is bad since it's really stiff to turn but I'm not sure how else I could confirm that.

@WordofAdviceTV 5 лет назад

Hey Michael! Even though the motor resistance readings are good, the motor still may be bad just like you said. The electrical windings may be fine but the motor bearing is not. If it is hard to turn I would replace the motor and capacitor. (the new motor should list in the specs which size capacitor it requires)

Ordered a replacement capacitor to match the existing. 70/7.5 MFD 370V Round Should my existing fan still not run (825 rpm ROT Cap 7.50/370 1.40A) can I replace it with a 6 month old motor from another unit? (1075 rpm ROT 5/370 1.8A) ? If so, can I still use the 70/7.5 capacitor that I just ordered, or must I downsize? What size should it be? The idea was to save money by using a motor I have versus spending $200 for a replacement 825 rpm unit. So grateful for your videos and your advice.

@WordofAdviceTV 6 лет назад

Well.. Generally that is frowned upon in the HVAC field. You will increase the RPM by 250. Keep in mind that the fan blade is designed for 825 RPM. Which means the noise that the unit makes will likely increase. (sometimes dramatically from all the extra vibration) It would also affect the efficiency and operating pressures of the unit. The refrigerant side of things may be thrown off a bit which can result in the unit not keeping up on hotter days. That being said... Yes, it can be done and people do replace motors with higher RPM replacements. Maybe you will get lucky and yours will work just fine. Or it may start to occasionally overheat and stop. Also, you could probably just get a different 5 MFD capacitor for the fan motor and use the 70 for the compressor. But with capacitors, going from a 5 to a 7.5 is a big difference and not recommended. I hope that helps! To summarize, I would not recommend it but it can be done and it probably will work. We do that in the field sometimes but only temporarily until we can get the right size.

@markverre1 6 лет назад

A million thanks for your complete and rapid response. I should have stated that I have the complete 1075 rpm motor, fan blade and grill and that I live in the desert of Southern California. 120 degrees here this week. My unit's brown wire was connected to FAN, Blue to HERM and Yellow to C. HOPEFULLY, the dual capacitor I have on order will solve my issue. Just in case... to utilize a separate 5 MFD and the 70 for just the compressor, I would be truly grateful for your wiring directions, should you find the time to reply. Might you have a recommended replacement and source for the existing GE Commercial Motors by Regal Beloit 5KCP39LF 825 RPM motor? With sincere thanks and deepest appreciation.

@WordofAdviceTV 6 лет назад

Oh boy, 120 degrees sounds mighty hot! Well if it comes with the fan blade, then that does improve the odds! It would be worth a try I suppose. But I agree with you! Hopefully the capacitor will fix it for you! That would be best. The wiring for a separate 5 MFD capacitor is pretty easy. If the new motor has 2 brown capacitor wires, then those 2 wires would simply both go to the new capacitor instead of the dual capacitor. If there is only one wire from the fan that hooks up to the dual capacitor, then you would put that wire on one side of the separate 5 uF capacitor and then for the other side you would put in a jumper wire going to the common on the dual cap. I hope that makes sense.. Unfortunately I am having troubles trying to look up the motor that you mentioned.. 5KCP39LF is that the part number on the motor itself? I think being that it is a commercial motor it will be harder to find the OEM since they mostly only sell to contractors. The most important part is that the RPM, HP, and voltage line up. The length of the shaft sometimes too. If the screw holes don't line up, you can always drill new ones.
