Normal operation – Stage 6
When the dwell time of 20 minutes has expired, the B-T LED goes off. The icemaker will go 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.

Diagnostic sequence – Stage 7
The 20 minute error LED (20M) is on indicating that the control board has sensed an over-torque condition
(above 3 AMPS on the gearmotor) and shut the icemaker down. The 20M LED will remain on for 20 minutes after
an over-torque condition has occurred. The icemaker will remain 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.
