Question and Answers

Q:

I have a compressor model 919167340. It blows breakers. There is nothing else on the breaker. What part do I need?

A:

Three things can cause the air compressor to trip a circuit breaker. If the compressor is running on an extension cord, move it and plug it directly in to a wall receptacle. An extension cord that lets the voltage drop can cause the compressor to trip the circuit breaker.

If the compressor only trips the circuit breaker after it has built pressure, the check valve might not be sealing off. This can cause it to trip a circuit breaker.

A bad capacitor or start switch on the motor can cause it to trip a circuit breaker.

A weak circuit breaker can cause the compressor to trip the circuit breaker.

Someone needs to check the voltage to the motor and the amp draw of the motor to determine where the problem is.

Q:

My Craftsman 919167340 compressor trips a breaker when I turn it on. Is it electrical or internal?

A:

Have you tried running the compressor in several different wall plugs? Do you know it isn't running on a circuit breaker that is already carrying a full capacity load? Does the breaker trip as soon as you turn the compressor on? Does the compressor only trip the circuit breaker when it is restarting?

Many times the fault is not in the compressor. Eliminate all other possibilities before replacing parts on the compressor.

If you will send another email and give us the answers to these questions, we will be glad to help.

Q:

air compessor

A:

Thank you for your question on the replacement pressure regulator and the compressor will not shut off.

Does the air compressor reach its 150 PSI target shutoff pressure?

You will have two gauges on the air compressor. One is for the tank pressure and one is for the regulated pressure.

The adjustable regulator just regulates the air pressure for the outlet into the hose.

If it does not reach 150 PSI then I would think you may either have an air leak or the compressor pump has become inefficient and will need repair.

Please let me know what you observe as it runs, and we can continue to troubleshoot with that information.
