... or rather it does stop, but not when you expect.
Yes, I am talking about that Craptor Supply / Craptersol Rank air compressor again.
I put in a full day in the shop yesterday. I was done, playing on the computer and sipping on an ice tea when I heard the compressor kick on and then kick immediately back off again.
I said the heck with that s*it, turned off the contacter and headed in the house. This morning I found nothing obviously wrong, but it wouldn't start. The breaker was tripped in the bub panel. I played with various ideas on soft starting the compressor, but decided to check the next obvious likely problem first.
I cycled the compressor on and turned it off. There was no hiss. I grabbed a wrench, loosened the line... and there was the hiss. The unloader has failed. Cold the motor has enough juice to start the compressor, but after running all day in a hot shop with 113-117F outdoors (more in direct sunlight) beating down on a metal roof the resistance was just to high. I can run for a few days the way it is, but I am about to order a new contacter and unloader. I suppose I should make sure I have a spare check valve on hand too. Yes you can sometimes clean check valves, but it usually doesn't last long.
Any day I expect the bung to blow out the bottom of the tank, or the compressor to throw a rod through the block.
In my opinion based on my experience Ingersol Rand and Tractor Supply colluded to defraud customers with this abomination.
