Compressor trips thermal switch and wont start
I have a cheap 15A direct drive HF compressor that won't start and trips the thermal switch but not the breaker. It will start from empty every time but wont start when the cut-in kicks on.
The compressor is on a dedicated 20A circuit I ran for this and I have checked the check valve which seems to be good. The unloader valve releases air when the compressor stops. Oil been recently changed. The confusing part is after getting it to cycle normally once, I can get it to start normally for up to about 30-45 minutes afterwards but if it sits for an hour or so, or more, it will go back to tripping the thermal switch.
It's in my garage on the opposite side of my breaker panel in the house (so I can't move it closer unless I want a compressor in my bedroom). I did test it on another circuit by bringing it into my kitchen which is about 15ft closer to the panel than the garage, and it kicked on fine. I'm in Louisiana so while it's chilly here, I wouldn't think it's cold enough to keep it from starting, especially since it starts up in the kitchen.
