Possible Causes
Incorrect temperature setting, Faulty temperature sensor, Stuck compressor relay on PCB, Airflow imbalance due to blocked vents
How to Fix / Troubleshooting
Safety: No immediate electrical work is required; unplug only if removing covers.
Steps:
- 1. Verify settings: Check that the temperature is not set too low. Adjust to a higher (warmer) setting and monitor.
- 2. Check vents: Ensure internal vents are not blocked by food, which can cause localized overcooling.
- 3. Sensor check: If overcooling persists, test the relevant NTC sensor (fridge or freezer) and replace if readings are out of range.
- 4. PCB suspicion: If the compressor runs excessively despite correct sensor readings, the main PCB may be faulty and should be replaced by a technician.
Tip: Use a separate fridge thermometer to confirm actual temperatures before assuming a fault.
