Diagnostic stages

High gearmotor amps – Stage 1
The HI AMPS error and TIME DELAY LEDs are on indicating that the control board has sensed an over-torque
condition at the P4 terminal (more than 3 amps from the gearmotor) or no current draw (0A) and shut the ice
machine down (strike one). The HI AMPS and TIME DELAY LEDs will remain on for 60 minutes after an over-
torque condition has occurred. The ice machine will remain off as long as these two LEDs are on. After the
60 minute time delay, these LED lights turn off, and the control board will try to go through a normal start-up
sequence.
