I am currently having a problem with my Kobalt air compressor. This is the high volume compressor with the vertical 60 gallon tank and runs on 240V. It has worked very well for about three years. I noticed recently that the motor runs fine but the maximum pressure I can get out of the compressor is 40psi. I also noticed that when I checked the filter at the top of the pump (which normally has a lot of vaccum) now has a small amount of air coming out of it. Any help is appreciated. Thanks.
