Possible Causes

Failed Adler main PCB relay outputs, Burnt trace on control board, Corrupted control firmware, Power surge damage

How to Fix / Troubleshooting

Safety first: Unplug the ice maker before opening the control compartment.

  • Verify power input: Confirm correct voltage at the Adler ice maker's power terminal block using a multimeter.
  • Inspect control board: Remove the control cover and visually inspect the Adler main PCB for burnt components, bulging capacitors, or discoloration.
  • Check fuses: Some Adler boards include onboard fuses; test and replace if blown, but investigate underlying causes.
  • Test outputs: In service mode (if available), command individual loads (pump, fan, compressor) and check for output voltage from the board. Lack of output with proper input indicates a failed board.
  • Replace control board: Transfer all connectors one at a time to a new Adler main control board, matching positions carefully.
  • Initialize and test: Restore power, perform any required Adler initialization or calibration, and run a full cycle to ensure E11 is cleared.
