While searching for air leaks I found that my 120V compressor is hot to the touch. I understand it may get warm if running frequently, but it runs about once every half hour and I have found the leaks and in the process of fixing them. The top of the manifold is just over 120 and the housing near the coils is over 200 consistently.

I do hear a humming prior to the pump coming on for a few seconds and an occasional humming and the compressor not coming on. I did order a new capacitor thinking maybe it may be the cause. For $12 its worth a shot.

Any one have any ideas or experience with this? These pumps are not cheap.
