5.2 WATER LEVEL CONTROL BOARD
The dual function water level controller is two controls on one
board. One controller maintains correct water level in the boiler,
and the other is low water safety cutoff.
The following trouble-shooting procedure will only determine if
the water level control board is working properly, it will not de-
termine why the board has failed.
This procedure exposes you to a shock hazard and must be
performed only by a qualified service agent.
5. TROUBLE-SHOOTING
1.
Check alignment of door. Realign if necessary.
2.
Check/replace door gasket.
3.
Check to be sure all pressure switch connections are
made.
