Monogram Overcooling / Thermostat or Sensor Miscontrol

Freezer is too cold; items near vents are freezing solid or showing freezer burn quickly.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Faulty temperature sensor, stuck relay on main control board, incorrect control calibration, user settings too low

Safety: Disconnect power before accessing sensors or control boards.

Adjust settings: Raise the temperature setting by a few degrees and monitor for 24 hours.
Check sensor: Test the freezer thermistor as described in E2. Replace the freezer temperature sensor if readings are out of range.
Inspect control board: If the sensor is good but the compressor runs excessively, the main control board may be stuck calling for cooling and may need replacement.
