2001 GA15 FF stays running in unloaded state
by German AutoSport
I have a 2001 GA15 FF Atlas Copco, compressor, Stays running in unloaded state
Hello, this compressor has worked flawlessly for years, according to the panel and the hours on the service items, it's fine.
It now will start up build pressure "loaded state" to 129 psi, then unload and stay running forever and won't shut down, I can use the air, and it will change from unloaded to loaded, build pressure but won't actually cycle down.
I opened her up and found a huge build up of dust and debris on the oil cooler, fans, etc, there's no alarm tripping but continues to cycle forever.
I cleaned a bunch and still same issue, on the bottom of compressor motor the high mark is just in there while in unloaded state, loaded it drops back into green, any thoughts?
