- I did what I could to try and get these people going. I had no idea what was really going on, and i was so exhausted that I began second-guessing myself. Tried to remember the basics and keep going forward, I think I got the right diagnosis.

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)
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!
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. 😊
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 😂
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
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.
Yeah, lesson learned
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.
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 !
Ya gosh darn right!!!
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
Man I hate the way I left the wire but we will go back out and tidy it up
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…
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.
Great job getting that unit up and working! Enjoy your weekend!
You too!! Thanks for watching!!
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.
Well the weird thing about it was the hot leg in that wiring from the switch to the furnace had no more continuity. I found a few staples it was crushed by but I couldn't find a conceise break. It was so confusing that's why I ran a new wire. Just mad I only had 8gauge with me 🙃
Great job
I would have check from hot to neutral if ok,then it's inside the air handler
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.👍
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.
Yeah, I think I said that at the end of the video. But that was the first time I came across that. It was so weird
Great work man.
Have a great weekend brother 🤟💯🌎
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
Just finished the video, good job lol. Remember with transformers and 120v, common and neutral are literally grounded. What that does is on the 24v side it no wires are grounded, each wire will have around 12v, once you ground one of them that one becomes the common and the other one becomes hot 24v. Same with 120 applications. Stay hydrated brother
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.
Do do do do do
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.
Correct
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.
Man that sounded like a poop show
Did you do a leak search to rule out possible leak ?
@@rafaelandreano no leak search.
I always use common never use the cabinet for ground
I used to use a small wire tie and jam it in the switch and its frame.
Stop testing to ground test to the other side of the neutral. We got a test for return voltage lost common.
Why don’t you just chill out and give the man a break he is doing exactly what we have all done in the field he’s still learning and he’s doing a pretty damn good job at it to he’s also got the balls to post his mistakes which I am most impressed and respected by but where’s your videos…??
Everyone has ran into this type of situation that he has most just don’t have the balls to post it on social media..
You do a good job always. however you need to learn a bit more about how electricity works. Other than that, good job.
30 years and counting for me. You are making the same mistakes we have all made. Learn from it and move on.
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.
DON"T check to ground!!!
Check to neutral.
Did you put the original transformer back in?
I didn't at the time but I didn't throw it away, it's still up there
It happens to us all brother...
Thanks for the understanding 🙏🏽
That would’ve got me too. Just always check all legs to a ground screw
Well that's the thing, to ground on the frame, where the ground screw was connected I would get 120, but from the hot leg for transformer to neutral on board I was getting 102. Idk why it was doing that but it was just 🤯
@@AB_HVAC
There is an issue with the grounding system or a potential fault in the electrical circuit. There could be voltage drop or resistance in the circuit between the transformer and the board. It could be a loose connection somewhere or some damaged wiring rubbing on something. My guess would be something loose and the vibration from the unit over time finished the job. It can create high resistance.
Let us know when you go back if you find it. I'm curious.
I had almost the same issue except the voltage side was blowing not incoming power issue. Low voltage fuse was not blown
Man, it's the fun part about the job tho
I work on a circuit that kept breaking down under load
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?"
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.
I have never had that weird of a grounding issue before. Normally if I do, it's like a grounding issue causing the flame rod to not read correctly during heat mode
Backstabbed switch
Seems like a bad switch. Falling intermittently.
So now you are returning voltage through ground instead of neutral….LOL
So now I'm giving people AC
