Follett 25CI400A - Diagnostic Sequences and Error Codes (7-10)

25CI400A/W • 25HI400A • 50CI400A/W • 50HI400A 27
Diagnostic sequence – Stage 7
The 20 minute error LED (20M) is on, indicating that the control board has sensed an over-torque condition (above
3A on the gearmotor). The 20M LED remains on for 20 minutes after an over-torque condition has occurred. The
ice machine 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  oat reservoir
senses water.

Diagnostic sequence – Stage 8
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 ice machine has experienced an over-torque
condition. If the ice machine runs without problems for 60 minutes and no additional torque errors occur, the 60M LED
goes off and the ice machine continues normal operation.
