Re: a/c problem

Will the fan run? Do you only have 22v at the ac? Have you checked the breaker? You also have to have 12 v at the wall unit. or your house batteries charged? Any of the 12 v lights work?

Do you have voltage at the thermostat?

Re: a/c problem

I think I found the problem.The thermostat has a low power bulb,the bulb has an open circuit in it,burned out.I think it is the ground for the circuit .I will know here in a little bit.
