CAUTION:
Check the contacts between the power interconnect module, the control board, and the power supply
board (Rev A and B units ONLY). Clean the contacts if dirty. If contacts are bent or broken, replace the
module. Proper inspection and cleaning of the power interconnect module contacts can eliminate a false
diagnosis of a failed control board or power supply board.
Check the contacts and connections of the control board. If good contact is not made at all connections
and ground points, false diagnosis will occur.
