Anyone do hvac? Got some questions.
I used to but nothing technical. Mostly building and installing duct work and condensation lines and stuff like that.Anyone do hvac? Got some questions.
Ac quit a couple weeks ago. Replaced the capacitor. Nothing. Today i replaced the fan motor. When i flipped on the unit from inside it made this crazy humming noise. Im thinking thermostat is fucked? Also the blades now seem to be really tight and dont spin freely. The motor is but a few hours old.I used to but nothing technical.

Ya they are tight now. I hooked everything up exactly how it was when i took it apart. No frayed wires.Blades are tight now? They should turn freely, did you check the motor again? Are there any frayed or burnt wires in the outside unit?
Does the outside unit come on at all? The fan turn? Is the motor burned up? All the wiring on inside unit good?Ya they are tight now. I hooked everything up exactly how it was when i took it apart. No frayed wires.
I really hope i didnt burn out the motor. 120$ i didnt really have.Replacing run caps, motors and thermo stats was about as far as I got on the technical part of the job. If you needed duct work installed or a return air cabinet built I was your man.
Humming usually means the motor is trying to turn but can't, I've seen them burn up immediately if there's a short somewhere.
Yeah, I had that happen at work. Turned out there was a wire that had the insulation get stripped off and it was making contact somewhere on the unit (HVAC did the work not me) and it was over loading the motor.I really hope i didnt burn out the motor. 120$ i didnt really have.
I know the heat works fine if that means anything.Yeah, I had that happen at work. Turned out there was a wire that had the insulation get stripped off and it was making contact somewhere on the unit (HVAC did the work not me) and it was over loading the motor.
Nah. You can run heat on most units without the outside unit at all. If we had a AC unit break in the winter time at my old complex we used to switch them over to some setting that by-passed it. I can't remember what it was now because these units at my current complex are completely different.I know the heat works fine if that means anything.
Check the contactor sure sounds like it's the contactor. They do go out pretty oftenThis is all the outside unit. Capacitor replaced a couple weeks ago and a literally brand new motor today. Hums loud as hell snd does not spin. I dont know enough about it to fuck with the in house portion of the system.
Yeah i have no clue what that is. Can you explain please?Check the contactor sure sounds like it's the contactor. They do go out pretty often
Pm me if you don't know what a contactor relay switch is.
It's the only thing in the compressor box that will chatter like that.
This is a contactor:Yeah i have no clue what that is. Can you explain please?
