Possible Causes

Bin thermistor out of range, blocked or dirty ice level sensor, sensor knocked out of position, failed control board input

How to Fix / Troubleshooting

Steps:

  • Turn off the ice maker and remove excess ice from the bin.
  • Locate the ice level sensor or bin thermistor in the bin area. Clean any ice, frost, or debris from around it.
  • Ensure the sensor is firmly mounted and oriented correctly toward the ice pile.
  • Inspect the wiring harness for damage or loose connections.
  • If the bin sensor is physically damaged or tests out of specification, replace it with a Marvel bin thermistor/ice level sensor.
  • Restore power and monitor operation to ensure the unit now stops making ice when the bin is full.
