Stop in for a cup of coffee

Last night about 2:00 a.m. laying in bed with her. I hear this humming sound. Lol. No wasn't her. Lol. This has happened before. The compressor runs whenever it needs to and apparently the belt jumped off of it again. So the electric motor just keeps running. The compressor is in a shed, insulated ,4x4 outside of the garage wall in the back. It is also just below my bedroom. Just got back from changing the belt. I admit I built the shed a little too small. Since it's only 4x4 ,the compressor takes up quite a bit of room. I can just get my skinny *** around one side to get to the belt in the rear. Three belts in 23 years. I don't guess that's too bad. :lol:
I want to set up a contactor switch connected to one of my lights. Lights off compressor off. Only way now is breaker or air valve. Pain in the butt.
