Diverter Motor Assembly Diagnostics
Diverter Motor Not Running
1. Operate the diverter motor is service mode.
2. Check for 120 VAC between pins 3 and 4 of the
diverter motor.
a. If 120 VAC is present and the diverter motor is
+5 VDC Out
not rotating, replace the diverter motor as-
Motor (N)
sembly.
b. If 120 VAC is not present check wiring between
the diverter motor and IMC board. If wiring is
ok, replace IMC board.
Diverter Motor Runs Continuously
1. Disconnect the diverter motor harness and
check for 5 VDC between the orange and brown
wires.
a. If 5 VDC is not present, check wiring to IMC
board. If wiring is OK, replace the IMC board.
b. If 5 VDC is present, reconnect harness and go
to step 2.
