Address soon - your appliance may not work properly

Also displayed as: C39 referenced in self-diagnosis text

What This Means

Failed ice maker kit; Bad wiring to ice maker motor; Main PCB signal failure at IC01 pin 90 (test switch) or pin 21 (motor load); Water valve failure — no water supply to tray

What actually causes this:

The ice maker mechanism in the fridge compartment has stopped working — the motor, heater, or sensor within the unit has failed.

First Thing to Check

Check that the ice maker arm is in the down position (not raised to 'off') and that ice maker mode is turned on in the display panel.

  4. 4

    Check MICOM IC01 pin 22 (blade ice scoop); should change 0V → 4.9V → 4.9V → 0V through cycle

  5. 5

    Verify water fills tray within 6 minutes of cycle completion

  6. 6
