Customer Question
I have a Payne...

I have a Payne Model PA10JA030-C, and it's currently not working. I've tried replacing the fuses and still nothing happens. I'm thinking it could be the a/c run capacitor but I'm not sure which one I need to purchase.

Contractor's Assistant: I'll do all I can to help. How long have you been dealing with this?

We haven't had our a/c for the past week.

Contractor's Assistant: Do you plan on doing the work yourself?

Yes

Contractor's Assistant: Anything else we should know to help you best?

No I think that's all I have. Other than the thermostat doesn't turn on but I'm assuming it's all linked together? My thermostat doesn't have an external battery supply for the lcd just fyi.

Contractor's Assistant: Just to clarify, do you think this is a larger HVAC problem, or something specific to the thermostat?

I know that the a/c probably could use a new run capacitor as we've never touched it in years since moving in. Any other time the thermostat never turned on, I'd replace the fuses and it would fix it.

Hello, Do you have 230 volts AC to the outside unit disconnect switch? If not check the breaker marked AC on your house breaker panel it may be tripped. If you have 230 volts there and you can hear the compressor humm heavily for a few seconds when you set the thermostat for cooling... then it could very likely have a bad run capacitor.

If you do not hear that heavy humm for 2 or 3 seconds, and the unit has been sitting idle for longer than an hour when you set it to cooling, then the capacitor is not the problem.

Tell me if the inside blower motor runs when you set the thermostats FAN switch to FAN ON... if not then its most likely a problem with the controls, anywhere from a bad thermostat to a bad printed circuit boar.

.

We can go from there without a time limit, In depth with as much detail as needed , after you rate this answer:

Select the 'finish and rate your expert link' near the top of your page and click on it. Over half of my customers forget to rate my work. That is something like yourself getting a 60% pay cut. Its not sustainable.
