Thank you for your question. I am sorry you are having a problem with the air compressor. The valve on the side of the pressure switch is a relief valve. When the pressure switch turns the motor off it activates a lever that pushes on the relief to bleed off the pressure on the pump and lines. It should leak out for a few seconds. If it is leaking longer than that, the problem is the check valve in the tank. The check valve is a one-way valve that allows air to enter the tank but not come out. If the check valve is dirty, the air will leak back out of the tank through the relief valve. I have posted an image below that shows how to clean the check valve. If cleaning the check valve does not cure the problem, you need to replace the check valve. Please be sure to unplug and drain the air out before attempting any repair. I hope this is helpful. Please let me know if you need further assistance.   Thank you for using Manage my life. Mark T.

Hi.. I'm having a similar problem.. the nob that I turn to turn the pressure up or down is leaking.. if I unscrew the nob all the way all the air in the tank will slowly leak out.. The image posted above is extremely tiny and I can't blow it up to read it.. Any ideas on how to fix this.. the compressor is less than a year old.. Thanks you

Hi, I also am having a simular problem. At first the check valve was leaking in the switch and I thought I needed to replace the whole switch. So I ordered a new one for Sears Parts Direct.Com. Got the new part and after installation I notice now the compressor runs all the time and won't build up pressure. What else do I need to do??

A:

The drain valve will unscrew from the tank and come out. Be sure to let all the pressure out of the tank before removing the drain valve. If there is pressure inside the tank the drain valve might come out like a missile.

With the drain valve removed you can probably clean it out. You can order a new drain valve at Parts Direct The part number is A17038 and the price is $3.58.

A:

You might have an air leak on the compressor causing the oil. Let the compressor pump up and turn off then use a mixture of dishwashing detergent and water to test for air leaks on and around the compressor.

If the valve plate or a reed valve inside the compressor is damaged, it will cause the compressor to pump oil. If you don't find any air leaks, you probably need to remove the head and inspect the reed valves and valve plate for damage.

The valve plate can leak high pressure air back into the compressor body and cause oil to come out of the intake.

If you remove the head, replace the head gasket.
