Diagnostic sequence – Stage 7
The 20 Minute Error LED (20M) is on indicating that the control board has sensed an over-torque condition
(above 3.5 AMPS on the gearmotor). 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.
Diagnostic sequence – Stage 8
When the 20M LED goes off, the 60 Minute Timer LED (60M) comes on. The 60M LED will remain on for 60
minutes from restart. A lighted 60M LED tells the technician that the icemaker has experienced an over-torque
condition. If the icemaker runs without problems for 60 minutes and no additional torque errors occur, the 60M
LED will go off.
