My name is Billy.
This caused by a relay on the circuit board labeled K7.
The problem is this relay is not field repairable. Occasionally you can tap the relay and it will release...but it will always stick again.
You have 3 options..
put up with it
have board rebuilt
buy a new board
I apologize but that is pretty much it.
