My 6 gallon Mastercraft oil less compressor will not start?

Mastercraft – Troy
Mastercraft air compressor
Obviously it was starting before, Troy. So, the tank pressure has dropped to below the normal cut in pressure setting, and nothing happens?
Start by using the PRV or tank drain to empty the compressor. Power it back up. Any change?
Next, use a voltage meter to check and see if you’ve actually got power going to the ON/OFF switch if there is one, and with the switch ON power is flowing to the pressure switch.
With the compressor powered on, and the tank empty, voltage should be crossing the switch and be on the motor side of the switch. Is it?
If power is not crossing the switch then it’s quite likely the switch has failed.
If power is past the switch then it’s likely a motor issue which we can explore further when you give us an update via a comment hear with what you found per the above, K?
