Shop air compressor won't turn on.
The air tank is empty. Electric service to the compressor is verified good. The auto/off switch is in the auto position.
I've noticed the auto/off switch seeming to be feel funny - no definite click when switched from one position to the other.
I'm thinking the switch has finally died completely.
Numbers on the controller switch show:
Catalog number 69LM2 Series C
Furnas Electric Company
Where can I find a replacement switch?
If what you are referring to as the auto/off switch is what I would refer to as the pressure switch (see pressure switch from site map) then it sounds like that might be a problem.
With the tank empty, and the auto switch set to auto, can you multi-meter the lines from the pressure switch to the motor to determine if power is actually getting through the switch to get the compressor motor running?
