Re: Roof Air Conditioner Reply #20 – October 13, 2010, 04:30:41 pm George,Check that BOTH legs of your 50amp service are supplying power. If you are hooked to 30amp, or if the "second" leg of your 50amp service fails, the rear air conditioner will not run.Check circuit breakers as well. Quote Selected
Re: Roof Air Conditioner Reply #21 – October 13, 2010, 04:43:09 pm JD We are on 50 amps and the ECM shows power on both legs. I also opened and closed the circuit breaker. No luck. Is there anything top side I should check out?Thanks, George Quote Selected
Re: Roof Air Conditioner Reply #22 – October 14, 2010, 08:01:48 am George, Depending on the type of thermostat they can be cranky and that would be the first place to start to troubleshoot. You will need to provide the model or type of thermostat that you have for that A/C to determine how to get around it to fire off the unit. Wiggling and giggling the switch on the thermostat may get it to run.Maybe post a picture of the thermostat, and someone might have specific info on it.Good luck, Quote Selected

Re: Roof Air Conditioner Reply #25 – October 14, 2010, 10:59:06 am George,Try wiggling the "on/off" switch. The thermostats seem to have a history of poorly mounted "on/off" switches. I resoldered mine and beefed up the mount. Turning on and off numerous times over the years loosened the solders. We went for a long time just wiggling it, until the DW said that I was "allowed' to fix it! Quote Selected

Re: Roof Air Conditioner Reply #27 – October 14, 2010, 06:44:18 pm Thank you, Barry. This is a bit above my pay grade of expertise. I'll get it looked at when we are in Nac. Quote Selected
Re: Roof Air Conditioner Reply #28 – October 15, 2010, 08:03:21 am Mike B, Mine acts the same way and I think I will takle that this weekend. For my propane heaters I installed a seperate rocker switch to bypass the on/off switch that is integrated with the thermostat. Those integrated switches are troublesome and when I get the 5 button one apart I may just bring out some wires and add an external switch.Barry, Thanks for the thermostat guide.George, Good luck Quote Selected
