Champion compressor runs in reverse when tank is full?

by Jonathan
(Parson Kansas)

The compressor runs great but when the tank gets full and shuts off it kicks the pump and motor backward and runs for 10 or 15 seconds. Making a awful noise.


Help.

Depending on the model, you probably have a bad check valve, and/or the exhaust valve(s) on the pump are shot, and/or the unloader is stuck.
