Possible Causes
Faulty refrigerator thermistor reading too warm, Stuck air damper letting too much cold air in, Defective main control board, Incorrect temperature setting
How to Fix / Troubleshooting
Safety first: Unplug the refrigerator before accessing sensors or dampers.
Steps:
- Check settings: Verify that the refrigerator temperature is not set to the coldest setting. Adjust to a mid-range setting and allow 24 hours.
- Inspect air damper: Locate the air damper between the freezer and refrigerator (often at the top rear of the fresh food section). Ensure it is not stuck fully open due to ice or mechanical failure.
- Test thermistor: Follow the E1 thermistor testing procedure. Replace if readings are inaccurate.
- Replace damper if needed: If the damper door is broken or stuck, replace the air damper assembly with a Magic Chef-compatible part.
