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 3A 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.
