Q:

compressoor 921166430---- hits10 pounds -then cuts out have to restart keeps trippin ---put new piston still doing same thing ? why

A:

LiveFree, I am sorry you are having a problem with your air compressor. We have found a defective check valve or a defective start device in the motor could cause this problem. To check the start device you can open the drain on the bottom of the tank. Then turn the motor on. If the motor quits after a short time I suspect the problem is in the start device. On most motors, this part is not replaceable. To cure the problem the motor would need to be replaced. This information is based on the unit is being used per the owner's manual. IE not on a long extension cord or inadequate power to the unit. If you need further assistance please reply below with more details and a model number. Thank you for using Manage my life. Mark.
