CRAFTSMAN air compressor model# 919.167340 keeps tripping the circuit breaker in the house.

by Manage My Life Last activity date:

the CRAFTSMAN air compressor model # 919.167340 keeps tripping the circuit breaker in the house. I put the air compressor on a 20AMP line so this very problem would not happen. the engine sounds fine when it's running. It will run for 5 seconds ( I timed it ) and then instead of tripping the motor breaker, it trips the house circuit breaker.

Mark, Thank you for the advice. I agree with you about the switch capacitor. The problem is that at the Sears Direct Parts web sight, they state that the part is no longer available. I tried every number regarding the part but was again told that it was not available. Any suggestions on how to get the part? You are probably off this Monday for Labor Day, hope to hear back from you on Tuesday. Thanks again, Bernie

You air compressor should be run on its own 15 amp electrical circuit. I have provided you with the requirements for the air compressor out of the manual. By what you have stated you have followed all of the requirements. I just have to make sure you are aware of them. Make sure the air compressor has a 120 volts supplied to it when it is trying to start.

If the compressor runs for 5 seconds and then trips the breaker, I would suspect a failure in the starting system. The starting system consists of the start capacitor, the run capacitor, and the start switch. these parts are located on the back end of the motor. When the compressor starts, it can draw double the rated amps. If the start switch does not kick out the start windings, it will continue to pull double the rated amount and trip the housebreaker. If you have an amp clamp and know how to use it, you could check the amp draw of the air compressor. If the amperage does not drop below the amp rating on the compressor, I recommend replacing the capacitor first. This is the only part of the motor that is available. If you have a capacitor checker, you can check the capacitor. The rating will be printed on the side of the capacitor.

I hope this is helpful. If you need further assistance, please provide more details below.

When an appliance doesn't work properly or gives out it can be very disappointing because you don't really know what is wrong with it or you might even have to buy a whole different appliance. A suggestion I have for you while you are waiting on your response from an expert is visiting the website to set services. I have attached the link below if you are interested in viewing while waiting on your response from an expert. Hope this helps, good luck
