I'm new to this site so please bear with me. An average of once per day I receive an inconsistent chirping coming from the ceiling approximately 2 ft in front of the refrigerator. When this noise begins, the appliances shut down; the fridge and TV antenna. The breakers don't trip yet when I manually shut off the appliances breaker the sound stops. This sound can last 5-10 minutes and then suddenly it stops and the fridge and TV antenna start working again. The strange thing about all this is that this chirping begins like clockwork approx. 1 hour after the sun rises and the coach begins to heat up. I'm lost!
