Dometic A/C compressor coming by itself.
Our A/C units runs great, but I heard the front unit compressor coming on without the fan. The thermostat was not even calling for cooling at that time. I turned off the breaker to stop it.
I went up and looked for a contactor or relay that was maybe defective, but didn't find it.
I now learned that a relay is built into a "relay control board." Do you know where I could buy one? It is a model 600315:321.
If at first you don't succeed, skydiving is not for you.
