Q:

Repair Air Compressor

A:

Thank you for the question.

I am sorry you are having a problem with the air compressor. The pressure switch has a pressure release valve that bleeds pressure from the pump so it starts easier. If air continues to leak out of the pressure relief, when it is turned off the problem is the check valve in the tank. The check valve is a one-way valve that allows air into the tank but not out. If the check valve is defective, air will continue to leak out of the pressure relief valve. You can try to clean the check valve before replacing it. I have posted the instructions for cleaning the valve in the image below. Click on the image to enlarge it. If cleaning the check valve does not cure the problem, you will need to replace it. The valve can be ordered from our parts website: Sears Parts Direct .

I hope this is helpful. Please let me know if you need further assistance.

If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website: Sears Home Services .

Thank you for using Manage my life.

Check the seals. Your details seem to indicate that air is leaking past the seals for that valve.

A:

You could have a failed check valve or internal problems with the air pump. I assume that the pump isn't filling the tank with any air since the air is leaking out of the DAC140 valve. I recommend that you have a service technician examine the compressor.

Q:

I have a Craftsman air compressor model 919155611. It leaks air from the flow valve. What is the part number for the flow valve? Does anything connect to the valve?

A:

You can not put a plug anywhere there is not one already. You might cause the tank to explode by doing that.

The flow valve should have the discharge tube that goes to the tank attached to it.

You can use part number DAC-140 on your compressor if the flow valve is bad.
