This could be a failed pressure switch or a problem with the pressure relief tube. Check on the switch to see if you can tell where the air is coming from. If it's coming from the little tube that ties into the pressure switch then it's the relief tube (pt AC-0028). If that's not where it's coming from then it could be that the pressure switch itself has failed. If that's the case you can order replacement number Z-AC-0375-1 from HERE .

Thank you for using Manage My Life!

Q:

What would cause my Craftsman air compressor model 919165070 to start only when the tank is completely empty?

A:

Most likely, the start capacitor has failed. We do not offer the capacitor as a replace able part. Your motor has two capacitors one is start and the other is run. You can remove the covers and visual inspect the capacitors it should be clean. If you see oil, it will need to be replaced. You should be able to find the capacitor locally from a HVAC supply company. If you are unable to fine the capacitor the motor needs to be replaced.

There is a slight possibility the pressure release on the pressure switch is defective and bleeding off the pressure when it shuts off. When the air compressor shuts off you should here an air leak for a short time after the pressure is released from the pump. I have provided you with an image of the pressure switch and an arrow pointing to the pressure release.

I have replaced the check valve as mentioned above, then replaced the start capacitor, and lastly the pressure switch-all with no change in the results. With any pressure whatsoever, the motor will just hum for a couple of seconds until the circuit breaker pops. This compressor has not been used that much for the motor to be bad. Is there anything else that could be defective? Is there a way to check the motor? The items replaced above have already cost one-third of a new compressor. Thanks for any help you provide.
