ADDITIONAL ERROR CODE TROUBLESHOOTING INFORMATION
When entering the main controller error fault recall mode after a fault 1or 2 has been detected, the service person will see a second set
of error codes. These secondary codes shown below give information on a specific failure that is internal on the control board circuit.
SERVICE TIP: Therefore it is important to re-check all troubleshooting actions of any system that supports an internal circuit failure
before replacing the main controller board.
