Belling Temperature Fluctuation / Control Instability

Freezer interior temperature fluctuates widely, causing partial thawing and refreezing of food.

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 thermostat or sensor, Defrost cycle too frequent or too long, Door opened frequently, Poorly placed sensor not sensing average temperature

Safety: Unplug before internal sensor checks.

Steps:

1. Monitor with thermometer: Place a freezer thermometer inside and log temperature over 24 hours.
2. Usage habits: Reduce door openings and avoid placing hot food directly inside.
3. Sensor placement: Ensure sensors are correctly clipped and not directly in the airflow of the fan or against the evaporator.
4. Replace faulty components: If fluctuations are extreme, test and replace the thermostat, NTC sensors, or main PCB as indicated by diagnostics.
