It was cold two nights ago and my compressor started acting up. It sometimes works normally for a cycle and then a ghost in the high pressure relief valve then evacuates the air I just put in. I warmed the bay and got it working normally , but after a few hours compressor would not come on. to stop the air evacuation from the release valve I separated the housing pieces and them put them together again and the valve close, but then the compressor tries to turn on for a moment and then nothing. The 12volt works fine and kicks in at 30lbs. I don't have any leaks as the air hold pressure for more than two hours and that includes using the door , toilets, etc. I just put in a new check valve and HPR valve 3 months ago. Any ideas for me when I take it all apart ???? Could the 1/2" check valve go bad ? I replaced a 1/4" one and all has been ok until some cold weather which was only at night.... I don't know where to start, except pulling it all apart. Any Help from Richard or Steve or Tom since you 3 write great explanations to stuff...
