Kobalt air compressor won't build up pressure
I was away from home and when I returned home I heard compressor running in garage. I thought that it bled down pressure and started running to build it up however when I checked ball valve was shut and there was no air leaks that I could hear.
There was a burning smell and pump was pretty hot itself, oil is full. I took off air cleaner and it looks like/smelt burnt. Compressor itself works but doesn't build up pressure. What could be problem. Don't want to buy entire whole pump if I don't have to, would rather rebuild pump myself if I have to.
Compressor is Kobalt K7060HFV
