GE Profile Temperature Instability

Temperature fluctuates widely, wines too warm at times and too cold at others

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 thermistor, Poor air circulation due to blocked vents, Control board calibration issue, Frequent door openings

Safety: Unplug the unit before accessing sensors or panels.

Check loading: Ensure bottles are not blocking interior air vents or packed too tightly.
Monitor with thermometer: Place a separate thermometer inside and log temperatures over 24 hours to confirm fluctuations.
Inspect and test thermistor: Check cabinet thermistor placement and resistance; replace if suspect.
Control board: If sensors and airflow are good but swings persist, the main control board may be misregulating and require replacement.
