Symptoms
• Refrigerator compartment not cooling properly or running too cold
• Freezer section working normally while fridge section is affected
• E02 error code displayed on the digital control panel
• Food spoiling faster than normal or freezing unexpectedly
• Compressor running continuously or cycling irregularly
• Interior light functioning normally despite temperature issues
Possible Causes
• Faulty temperature sensor in the refrigerator compartment
• Loose or corroded wire connections to the temperature sensor
• Damaged sensor wiring harness from age or vibration
• Control board malfunction preventing sensor signal recognition
• Sensor positioned incorrectly after recent service or cleaning
• Power supply fluctuations on the 120V household circuit affecting sensor readings
• Sensor failure due to humidity or condensation exposure
Safety Checks You Can Do
• Verify the refrigerator is plugged into a dedicated 120V outlet and not sharing a circuit with high-draw appliances
• Check your home's circuit breaker panel to ensure the breaker for the refrigerator is in the ON position and has not tripped
• Unplug the refrigerator for 60 seconds to perform a hard reset, then plug it back in to clear temporary errors
• Ensure the refrigerator is level on the floor using a spirit level; adjust the front leveling legs if needed per USA installation standards
• Inspect the refrigerator door seals and gaskets on all compartments to confirm they are clean, flexible, and sealing airtight
• Verify temperature settings are within the recommended USA range of 35-38°F for the refrigerator compartment and 0°F for the freezer
• Check the condenser coils at the back or bottom of the unit for excessive dust buildup and gently vacuum if needed
• Leave the refrigerator unplugged and wait 10 minutes, then plug in again to allow the control board to recalibrate
• Monitor the error code to see if it reappears after the reset; persistent errors indicate a sensor or control board issue requiring professional service
Safety First
