Diagnostic sequence – Stage 7
The 20 minute error LED (20M) is on, indicating that the control board has sensed an over-torque condition
(above 2.5 AMPS on the gearmotor). The 20M LED remains on for 20 minutes after an over-torque condition has
occurred. The icemaker remains off as long as the 20M LED is on. When the 20M LED goes off, the control board
will try to go through a normal start-up sequence. The WTR LED remains on as long as the water sensor in the
float reservoir senses water.

Normal operation – Stage 6
When the dwell time of 20 minutes has expired, the B-T LED goes off. The icemaker goes through the normal
start-up sequence when the bin level control signals the control board for ice. The WTR LED will remain on as
long as the water sensor in the float reservoir senses water.
