Do you have any advise on how to replace a relay switch on a motorhome basement ac?
The ac continues to hum when I've turned it off and has been humming now for 3 or 4 days in a row. I am in TX so I'm dependent on ac. It cools when I have it turned on. When the compressor does shut off it tends to come back on in about 3 seconds but keeps me cool all day. If I run it over night, (seldom now), it continues to cool below setting.
