Just found you guys a few days ago, of course, trying to solve a problem. When you turn on the AC the compressor comes on and runs until it freezes up, then shuts down. Problem is the fan will not kick on in any setting. I have tested the relays, the fan motor, and replaced the control panel/ relay board, and thermostat. I can't find any thing else to replace or check. Anybody have any ideas?
Thanks,
Bob

Bob, welcome to iRV2.com. We are glad to have you join us here. Sorry to hear the air cond. is inop. When you say you have tested these various components; what results did you find on power to the motor? If you found voltage to it under a load did the motor turn? If you will give us the model # of the air cond. and of the thermostat, we might be of more help. Also include the year, make and model of your coach as this may shed some light. THanks

RV Wizard,
I have a 26' Skyline Layton 5th wheel. The AC is a Brisk Air 13,500, the model No. is 57915.531. My motor test was to put 120 volts to the wires that correpond to the motor at the plug that connects all of the power to the relay board. As far as the capacitors go, I took them to an AC supply house with the thought of just replacing them, he ended up testing them and said they were both good. I'm out of ideas now.
Thanks,
Bob

Bob, I recommend you run a continuity test on the low volt wiring from the T'stat to the Air Cond. low volt wiring connection. I suspect an open circuit for the fan speed. If you have an extra (unused wire) in the run you could switch over to it if you find this to be the problem. Good luck.
