Possible Causes
How to Fix / Troubleshooting
Step 1: Verify settings
- Set refrigerator to recommended temperature (around 37°F / 3°C).
- Avoid using the coldest setting unless necessary.
Step 2: Check damper operation
- Locate the air damper and listen for movement when adjusting temperature.
- If always open, replace the damper assembly.
Step 3: Test thermistor
- Access the fresh food thermistor and measure resistance; compare to the tech sheet.
- Replace if readings are out of range or if sensor is shorted.
Step 4: Control board evaluation
- If damper and thermistor are good, the main control may be failing to cycle the compressor and should be replaced.
When to call a technician: For control board diagnosis or if the compressor never shuts off, professional service is recommended.
