[AT] Air compressor failure

[Spencer Yost]

I have the exact opposite problem (but probably same root cause)  with my water well pressure switch.  Every once in a blue moon it will fail to cut the pump on when the pressure drops below it’s rated psi. All I have to do is cut the power, run a little emery cloth over the points, and then all is well for another long while.  

PS:  Cut the power first!

I'm going to check a few things that you folks have asked about and see if any are contributing such as low compressor oil, plugged intake filter or a leaking outlet line and see what happens. Thanks for the suggestions.
