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.

The second error (2ND) LED comes on if an over-torque condition occurs while the 60M LED is still lighted.
The 2ND LED indicates that two consecutive over-torque situations have occurred. The ice machine will be
