05 Montana AC problem

[TCI]

Hi all, our friend has a 05 Montana 5ver with the dometic thermostat control. The furnace part works fine, but the AC nothing happens, the fan won't even turn on. Any ideas? As always, thanks!!

First of all reset the ac circuit breaker on the electrical panel.

If the ac still doesn't run, the only thing I can think of at the moment is get the thermostat manual out and check that all the switches are set correctly. If he does not have a manual for the thermostat you can go on line and download one.

If everything is set correctly then it is either wired wrong or the thermostat is bad.
