Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hello and welcome to Just Answer. My name is ***** ***** I will be happy to assist you with your electrical question.
1) Take a look at the nameplate rating located on the compressor motor. What is the FLA (Full Load Current) rating of the motor. How many amps? What is the voltage and horsepower rating of the motor?
2) Did the compressor previously work OK prior to tripping the breaker or is this a new problem?
3) How many amps is the breaker? What size are the branch circuit conductors?
4) Does the breaker trip upon the motor start up or a few minutes after the compressor is running at full speed?
No problem, I will opt out of the question then. Possibly another expert here can assist you.
Since it has been working correctly, I would suspect either warn out motor windings or a defective pressure switch. A defective pressure switch would be the 1st component I would check for.
No need to reply back to me. You will be notified when another expert picks up the question.
Why din't you have both capacitors checked? One is start capacitor , other is the run capacitor. Likely the start capacitor is bad!
Replace the start capacitor!
I can call if you like , but a start capacitor would be cheaper!
The capacitors are not identified in he Sears manuals, but electrical supply that sells capacitors can tell which is start, and which is run, they have different ratings.
Thank you, ***** ***** to close.
