I have a Husky 30 gallon lay down compressor. Model number WL651004.

The compressor upon initial start up runs and shuts off at around 125psi.

After that while you are using it. It will no longer cycle back on.

You have to unplug it and wait approx 5-10 minutes. When you plug it back in it will run up to operating pressure and then shut off again. Only to not cycle when the pressure gets below 80psi.

I have thought that the pressure switch makes sense to be the culprit. Because it would seem that it may be getting stuck in the open position. However I decided to post the question on here for you before I purchased a new pressure switch. Especially after reading your article pertaining to how the pressure switch is not always the issue.

Chris, as a comment here, could you please tell me what happens when the pressure in the compressor tank drops to below the normal cut in pressure? Does the compressor try to start and it cannot, or does the pressure just drop down past the normal cut in pressure setting, and nothing at all happens… no clicks, no whirring, no noise?

Before you comment, check this out for me, and the let me know what happens, please. When your compressor tank air fills to normal cut out watch the UNLOADER VALVE toggle on the side of the pressure switch to see if it operates. There should be a little blast of air out of the unloader valve when that happens. Is this occurring?

As another check, with a full tank of pressure, pull the plug, open a line with a valve or blow gun, or even the compressor tank drain, and slowly drop the pressure. Watch the tank gauge to see when your tank pressure is approaching normal cut in setting, and then pay particular attention to the pressure switch. What do you see/hear when the pressure falls past the normal cut in pressure setting. There should be a response of sorts and if nothing happens, then it might be the pressure switch that is the problem.

Bill, Thank you for your reply. As far as the first question goes. When the pressure drops back down to the setpoint, nothing happens. No click that I can hear, no interactivity from the motor, etc.. I will pull the cover off of the compressor this evening or tomorrow and check the valves on the pressure switch as you noted. I will check for movement or any activity of sorts from the switch. Also when the compressor turns on and runs up to pressure. It shuts off with the slight burst of air you mentioned as it reaches its normal pressure. I will check these things and get back with you.

Thanks again
