Q:

Compressor Noise 919162120 Craftsman Air compressor

A:

Thanks for the inquiry and for being a valued member.

I am sorry to hear of the issue you're having with the compressor. I know how frustrating that is.

This compressor is a permanently lubricated unit, and no maintenance or oil is required. I would recommend checking for air leaks. You may also want to check the belt, as it could be slipping. There is also a valve plate under the head that has reed valves that may be warped and not allowing it to build pressure. 

I was able to locate a manual for a very similar model. I have linked it below for convenience.

Hello Jim,

I'm sorry to hear that your air compressor is not making it to it's preset pressure and I would like to assist you. I need a little more information, does the compressor act like the pressure switch is shutting it down, or does the motor stall? I suggest unplugging the compressor and verifying all of the wiring, if the compressor seems to just cut out electrically. It is more likely a bad connection than a failed pressure switch. If there are not any wire connectors that are found to be faulty, you may want to verify if there is constant voltage to the motor. Follow safety precautions when working with line voltage! Use a multimeter to measure the voltage from the contacts on the pressure switch to the motor. If the voltage drops out when the pump shuts down, it is a switch issue. If the voltage stays constant, it is a motor issue.

Please let me know what you find. I look forward to assisting you further.
