No A/C Service Call That I Will Not Forget | HVAC 

Those who have been there probably knew immediately it was a dropped neutral. Always check line to ground and line to neutral every time. If they don’t match the neutral is open.

No, You were perfectly correct in saying. "Thank you Jesus" at the end of the video! I have worked field service for 46 years and when I gave thanks for finally getting the answers I need, I got more help in the future. FYI, this also works in all my life's troubles. (I am now 69 years old).

Stupid and accomplished at the same time 😂 glad to know that I’m not the only one out here! Great work man!

I always check for VAC across the incoming wires. Also you violated code and safety by using the ground for a neutral return. If a problem develops in the ground and it opens - the entire indoor unit can become energized to 120VAC due to the back feed from the hot wire. Since you had a hot and neutral wire problem, it is entirely possible to have a ground problem arise. (I know that you did it to get them by)

You ain't stupid bro you're a professional

A good self-assessment of your work isn't a bad thing. Every call is a learning experience. Good job AB!! Enjoy the weekend. 😊

I know the feeling, brother. I've been doing this for 5 years and still have calls like this. Working long hours and in the heat, you can't always think straight.

Hey buddy I used to live in Conyers GA. right off of 20, and worked for a company called Reliance heating and air, I've been in those attics in the middle of July and that shit ain't no joke!!!!! the heat coming of the sun is unlike anything I have ever felt before you can feel your skin cooking!!! anyway I moved back north to southeastern MI GOD BLESS YOU BROTHER

I feel you champ. It's happens In this hvac field. On Wednesday everything went wrong and was second guessing myself. Making rookie mistakes 😂

Sounds like u lost the neutral. I always check the hot and neutral for 120, instead of only hot to ground, because that only tells 1/2 of the story.

Hi bro, Great job!. I think it was a loose neutral wire in the circuit. Check in the switch box and all neutral wire connections.

I like your video I would slow down and explain exactly what you did I have learned a lot watching Keep up the good work

You still need to fix the lost neutral wire. Jumper Line neutral to cabinet ground should not substitute for a missing neutral. Any unused current is returning thru the cabinet to find earth ground. Dangerous situation for next service person.

I always check on furnace boards from hot to actual neutral. I’ve had skewered readings from reading to ground before and it’s got me all messed up

I would have check from hot to neutral if ok,then it's inside the air handler

Been there done that! I know the feeling when you finally get it working. Good job keeping with it until the end. Mama aint raise no quitter !

When ur in an attic like that it's very hard. Take breaks. Lol.lol. I luv ur attitude.

I would have done the same as you did and I did learn something new thanks

Watched a few of your videos, fun watches. Old tech here., Remember from school and keep to this day. LINE, CONTROL, LOAD, RETURN. Have a good weekend.

That has happened to every tech…if you get to the point of exhaustion then EVERYTHING seems to go backwards…

Great job getting that unit up and working! Enjoy your weekend!

Hope you go back and remove the code violation (neutral to frame ground) which it is unsafe for other techs and residents if the ground ever opens. I'm an industrial electrician of 40 some year's and this won't be your first and last head ache. Been there several times through out my career. You can never stop learning because electricity is like an open story book with no ending. Keep up the good work and keep those videos coming.👍

To me happen almost same thing,with carrier furnace , couple models have a safety it working with ac and heat crazy rigth, have power on all the unit except on comun and red almost make me crazy. Call a experience technician and he told me cheq for rollout and presure switch and guess what a freaky roll switch wasent work that wy dont have 24 volt on my slot for thermostat 😅😅😅😅 they conected in secuency for the whole unit and go back to 24v on the board.

Yeah always check from the hot leg to neural. I like a meter that has a LOZ setting for ghost voltage also when checking A/C Voltage.

Like to see you trying to learn. Your Neutral wire is lost or broken to the furnace. Need electrical work. Should always check voltages from common to power or power to power. Never line one to ground. Transformer was not bad.

I had almost the same issue except the voltage side was blowing not incoming power issue. Low voltage fuse was not blown

DON"T check to ground!!! Check to neutral. Did you put the original transformer back in?

Great work man.

Don't rely on chassis for 120/240 measurements. Also, sometimes the 24 vac common is not connected to chassis.

I had to watch this a couple times. So your nuetral on your board wasnt grounded properly and was recieving less voltage overall, so you connected it to a grounding screw and got the correct voltage.

Have a great weekend brother 🤟💯🌎

I always use common never use the cabinet for ground

So I got a call on a 100% OA unit today. Water leak on ceiling tile, 2nd time, I’m #2 on this call. Get to site, do a visual on roof. Notice refrig flashing in sight glass both compressors running. Hear belt squeaking, open panel and belt spinning faster than pulley😂😂. Head back down, pop ceiling tile, notice there’s a return in ceiling. 24 x 24 Eggcrate return is plugged. 4000 cfm with about 85% fully plugged. So, not 100% OA unit after all. Bottom of OA unit has heavy sweat, which is dripping on ceiling tile. So I get up on a ladder, turn flashlight off and notice sunlight coming in all 4 sides of curb. Fix, clean RA grille, spray foamed gaps to seal curb, change belt, add refrigerant, fill sight glass. Unit no longer sweating on bottom side. 5 hours. Just my day. It is hot. I’m in AL. So my prognosis, lack of return air, loose belt, under charged refrig level, no load on coil, coil got very cold, outside air through curb infiltration, dewpoint issue on bottom side of curb metal plates from all of the fore mentioned and wa-la, rain on the ceiling tile. Nice vid A.

I work on a circuit that kept breaking down under load

It happens to us all brother...

Do do do do do

Those switches sometimes get hot and crack causing the power to not go through them. Sometimes if you jiggle the switch it will turn on intermittently. Then you can just replace it. I haven’t finished watching so I’ll see what your conclusion is.

You do a good job always. however you need to learn a bit more about how electricity works. Other than that, good job.

That would’ve got me too. Just always check all legs to a ground screw

I never tape the door switch. I just cut out the door switch and wire nut the leads. I knew you were checking the ground wrong but you figured it out. As long as you learned that's all that counts.

30 years and counting for me. You are making the same mistakes we have all made. Learn from it and move on.

Austin, in this stage of your career, you are doing great. Keep learning all you can. Sometimes when something appears to have two or more unrelated problems, and the unit has worked recently, you gotta ask yourself "what is the likelyhood of these two things failing at the same time?"

Seems like a bad switch. Falling intermittently.

Backstabbed switch

So now you are returning voltage through ground instead of neutral….LOL

Stop testing to ground test to the other side of the neutral. We got a test for return voltage lost common.
