Possible Causes

Stuck-closed mechanical thermostat (on older Maytag models), Failed refrigerator thermistor reading too warm, Faulty main control board not cycling compressor off

How to Fix / Troubleshooting

Safety: Unplug the refrigerator before accessing controls or sensors.

  • Check temperature settings: Ensure the control is not set to the coldest setting. Set to mid-range and monitor.
  • Verify airflow: Avoid blocking vents with food; poor airflow can cause localized freezing.
  • Test thermostat (if mechanical): On models with a dial thermostat, turn the dial from coldest to warmest and listen for a click. No click may indicate a stuck thermostat.

If the unit continues to run nonstop and temperatures remain too low, the thermostat or thermistor should be tested and replaced as needed. Persistent issues may point to a faulty main control board.
