How To Install A UNIVERSAL Blower Motor And Save Hundreds Of Dollars 

Yea. I was about to say. Most times a hum like that is a bad cap. Easy way to tell if its a bad cap usually is spin the blower wheel with your hand and hit the switch to make it hum like u did before if it takes off running it’s usually a bad cap.

You did the right thing..... I've never replaced a blower motor without a new capacitor.

Hi HVAC guy, What does a company charge for this? Thanks

Thank you :) I do my best

Or burn your house down trying 👍🏻👍🏻

@@scott5654 He showed every step needed. Why the hell does every HVAC service tech think that people are incapable of following wiring diagrams, simple instructions, and sound advice? Thumbs up, thumbs up, hashtag I'm an expert.

Personally, these days, I wouldn't trust a certified hvac technician to put air in a bicycle tire. Maybe just my area and there are some that actually do a good job (or what they show themselves doing on RU-vid) but the cons outweigh the pros. Actually goes with every certified businesses these days. If it ain't theirs, fuck it. Don't know if it's lazy, job security or not giving a shit but.... No. I guess in bigger cities where there's code to have this done they might do a better job but here with no codes they are crap

Peace and blessings, Lala! You are the one in a million! Good fortune will smile upon you!

Thanks for throwing this out there, it is good information for me.

In my case I was able to find new bearings... brass sleeves in a body of plastic material

A good mechanic never fears competition.

Yessir The capacitor and blower always seems to go "stinko" when it's a -20*F blizzard outside at 3:00 a.m.

Brilliant! Thanks so much!

This was a rental property and they kind of do the minimum. I could let the blower wheel slide though. It was super nasty.

@@diyhvacguy *couldn't

@@diyhvacguy Shouldn't matter if they are on time with their rent etc.

Yea, you could have taken that circuit board outside and gave it a good hosing with the garden hose! Service is dead

@@diyhvacguy ...rental property. Yup, same as up here in Alberta. The ' owners ' just dont actually GIVE A DAMM. Eavestrough falling off, for 3 or more years; sheds full of mattresses/boxsprings/frames. Washer/dryers/stoves, etc in yard, under trees. NO ONE CARES, anymore = GREEDY FOR PROFIT. No surprise, to me at all, that the furnace is a dirty disgrace....

exactly why I prefer the less sophisticated furnaces. Of course if it’s under warranty it’s free :)

Well, 15 minutes is a gross exaggeration. I mean, I’ve only changed four or 5000 of those blower motors, and I am not as good as you having only done the one that you own. It takes more than 15 minutes just remove the blower assembly and reinstall it.

What did you end up doing? ECM motor died in my oil furnace and I'd love to be able to swap it.

Converted it to a standard fan with a capacitor.

@@hkgonra Did you do the conversion yourself?

I did not, I called in a much more experienced HVAC guy. He was actually an electrical engineer in Ukraine but came here and got into HVAC. Nice guy to have on speed dial. LOL @@theelmokiller

@@Kevin-mp5of Generally that is untrue however, there are millions of imported products that are just as good as USA or better but most of the time they aren't going to include electric motors or other mechanical devices. I have seen lots of hand tools from imports that are dandy and other things. Not to mention "made in USA" has been pimped out to include imported parts and imported assembly can bear the name if it meets a certain percentage of parts and assembly here in the USA so just because it says USA doesn't mean it really is a USA quality product. Brand loyalty is a thing of the past and it appear the brands are responsible for that some.

I had a Heil Furnace/AC that once it was about 10 years old I could hear from the attic a barely audible bearing whine when the fan was on. I had pretty good hearing despite loud stereo music and concerts in my youth. I found that the USA made motor actually had oiling ports, so then and every few years after that when I heard it again, I would pull the motor/fan out and oil it with a few drops of Zoom brand oil from an HVAC supplies shop. I understand now they are made sealed and you can't lubricate them. I would also visually inspect the heat exchanger for rust and cracks and clean out an dust and lint inside the unit. The only thing I couldn't get to, to clean, was the A style evaporator coil which I was just sure was coated with crud. Even though I knew my furnace was probably good for another 20 years, the system wasn't cooling well and I let them talk me into a new Lennox a couple of years ago, saying my condenser fan was bad-drawing too many amps(all it needed was a new cap I now know) and my compressor was testing weak -drawing too many amps-maybe true, maybe not. They also claimed the parts were obsolete now. I actually believed all that, because the condenser unit was the second one for that system-first one, the compressor conked out. Also the system was 25 yrs old, and R22 is sky high expensive. They left me overnight with a temp "replacement motor". When they took it all out the next day, the evaporator was very clean. I don't know why it wasn't cooling well but I have the feeling I got "took." Now this new Lennox sweats a lot and collects water in the pan, and now I see that HFC 410A is now being banned anyway! Great. I'll say one thing, after I have educated myself with all of these YT videos, the next time they better be pretty damn good to fool me, if that's what they are doing.

@@freespirit1975 Always be aware of confident artists and those who only know the classroom facts. The experienced tech who is there to represent you first is the one to hire.

@@freespirit1975 You did good in that case. Family shops tend to be better however, not less money.

@@Garth2011 "there are millions of imported products that are just as good as USA or better" No, there are not. The only times they are better than American made are when there is no similar product made in america. Slave labour and 12 year old chinese kids do not take any pride in their work and the chinese QC is mostly nonexistent.

Thanks so much! 🙏🏻

Yes they can be used in the burner side no problem. Obviously you don’t want anything that close to the flame but in that area where all the factory wiring is, is totally fine 👍🏼

I agree 100% with that

I've always used standard pleated filters. The blue fiberglass filters that you can read a newspaper through are no more than BUG CATCHERS. LOL

double stack the mesh style and never use the pleated filters.

You can get better airflow by using the thinner cheaper filters The strain on the motor from trying to pull air through a denser filter isn’t something that happens with squirrel cage blowers (or any centrifugal fan) since they’ll just keep spinning existing air around inside the blower housing.

Thanks so much!

Yes, clogged filter, blocked vents or returns, clogged blower wheel, maybe a capacitor. Does it have any codes?

🤣

I’ll for sure do that next time I run into one.

I’ll do some research on this. I believe they are coming out with a wired soft start for residential ac so I’m curious to see how that works! Stay tuned! Cheers

Depends on resistance to airflow. Too little and the heater will overheat . . . and so on

I’ll do some brainstorming on this! Cheers

If you live in a cold northern climate, stick with the gas furnace. You'll be glad you did.

You should have a technician come out and do a combustion analysis and see if there is an issue with the gas/air ratio. Sounds like it’s sending a lot of unburnt fumes out the vent.

They’re called products of combustion, they’re not supposed to be pleasant.

The last thing you want is to be fixing it in the middle of summer, so my advice would be to replace. If you need some help locating the right equipment and finding a good price, email me at diyhvacguy@gmail.com Cheers

@@diyhvacguy even if it still operates good?

@@marrowsteven Run it until it dies! The new equipment is built like JUNK!!!! As long as you have back-up resistance heat for winter, you'll be able to limp through the cold until spring when you can decide to replace or repair. My heart is old, still works fine, but I never thought of replacing it!

There very well could be.

Yes absolutely.

My apologies, I meant to say the capacitor was GOOD 😂 I have a habit of mixing my words while on camera. Sorry for any confusion.

@@diyhvacguy No worries.

If you’d like technical support check us out on Patreon.com/diyhvacguy Due to demand, I can’t answer tech questions on here without more info. Cheers

@@diyhvacguy , It’s not due to demand, you gave up the answer when you asked him to pay for your answer.

And this is exactly why you shouldn’t do things yourself.

It may not work. Furnace starts the fan on heating and t-stat starts the fan on cooling. There may be a way to do it but I don’t give DIY advice.

@@caru3257 Thanks, was just curious. I have a two speed furnace, no cooling. Generally runs at low speed for 10 minutes, unless really cold out and needs to run for longer heat cycle.

No, these little ones with the two brown wires don’t matter which wire goes to which terminal. The ones with a dedicated c terminal do matter though.

Yes

This one was neglect for sure. You saw how dirty it was. They never changed the filters and overheated it I’m sure. Always keep your filters changed in a regular basis! Cheers

@@diyhvacguy is using too high of a filter level a stressor?

Oh yeah, this what happens when people think they can watch a video like this and then they automatically became an HVAC technician. There is a shortage of techs because the job is touch and the working conditions suck most of the time. Hopefully no one gets electrocuted or gets their hand sliced open doing this work!

It sounds like a failing blower motor. If you turn the power off you can spin the fan manually and if it has some resistance the motor is on its way out.

The gas isn’t really needed since you are only messing with the fan but it’s always a safe practice. I typically just turn the switch off but I’m sure everyone will say to turn the breaker off just to be on the safe side 👍🏽

@@diyhvacguy thnk u🤙

So the heat and air work but it’s just always blowing air regardless? If you want to email me at diyhvacguy@gmail.com I can try to help you out

There is a BLOWER RELAY on the circuit board. That blower relay has a very tiny electrical arc on the CONTACTS of the relay. Over time.... these small minute little arcs can cause the blower relay on the circuit board to STAY CLOSED. . With the heat and air in the OFF POSITION......AND THE FAN IN " AUTO " . That is most likely the culprit. If you give the blower relay on the circuit board at this time. And the blower stops. Then that's about a 95 % chance that is your problem. Blower relay is usually black and about the size of 2 regular DICE put together.

I have the same issue on a new universal motor i put in on a Rheem motor won't shut off at all unless braker is off this is a 12 year old unit no board on furnace did anyone resolved this issue?

@@geudirosario-nu5qi is it an electric furnace ??

It was a rental that was beat up and it was very late when I did this replacement. I was ready to go home! HHa

@@diyhvacguy Ha Ha, I can relate! Was just curious.

@@diyhvacguy That's really not a customer inspiring reply... Regardless who the customer is, you are still getting paid to do a respectable job.

This video was filmed in a super gross apartment, and at 9:00pm I might add. I was not inclined to spend any more time then needed. I simply couldn’t put that blower wheel back in the way it was though.

@@diyhvacguy Yep, been there, done that; working overtime will do that and TYVM.

It’s in the video description, right under the video, there is a more button with 3 dots. Alternatively, here is a link :) : www.amazon.com/shop/thediyhvacguy?ref=ac_inf_tb_vh

It's not his. What does he care.

It’s a run down rental. They only have me do the minimum but I couldn’t let that blower wheel slide. Cheers

Not sure on this. I picked this one up at the local Johnstone supply, so they made sure it would work for this furnace.

Well I’m an hvac contractor but sometimes if you go in and act like you don’t know any better they will sell you a part :) I’ve seen it happen first hand a few times while I was in there picking up a part

I checked the capacitor and it wasn’t out of spec. The motor was definitely bad.

@@diyhvacguy you stated in the video that the capacitor was bad

@@craigkohler2641 correct, that happened at 0:36 . Dave, did you misspeak in the video?

Tell me!

@@chezchezchezchez There are a pair of short wires that you can switch to make the blower run the other way. There is a big tag on the wires that explains it but you do need to check that the blower is going the right direction before you finish. The one he was working on needed to run ccw to blow air up into the cabinet.

@@ohiopat 🤣🤣CCW ???

@@scott5654 counter clockwise

@@aland680 It goes counterclockwise from both directions. If you’re looking at it from the right side and it’s going counterclockwise is that correct? Or if you look at it from the left side and it’s going counterclockwise, is that correct? This is no minor technicality. CCWLE is an important thing to understand, isn’t it?
