Diagnostic Sequence - Stage 7; Diagnostic Sequence - Stage 8 - Follett Symphony 25HI400A Installation & Service Manual

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). 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.

If the restart is successful the 20M LED goes off, the 60 minute timer LED (60M) comes on. The 60M LED remains on
for 60 minutes from restart. A lighted 60M LED indicates 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 goes off and
the icemaker continues normal operation.
