Problems you may notice
• Refrigerator displaying E1 error code on the digital control panel
• Inconsistent or incorrect temperature readings shown on the display
• Compressor running continuously or not running at all
• Freezer compartment becoming too cold or not cold enough
• Fresh food section warming up unexpectedly
• Inability to adjust temperature settings through the control panel
• Interior light functioning normally despite temperature issues
• Audible beeping or alarm sounds accompanying the error display
Possible Causes
• Faulty temperature sensor in the refrigerator or freezer compartment
• Loose or disconnected wiring between the sensor and control board
• Malfunctioning thermistor component in the temperature sensing circuit
• Control board failure or software glitch
• Moisture or condensation damage affecting sensor connections
• Failed connection at the sensor plug due to corrosion or damage
• Power surge or electrical fluctuation damaging sensor components
• Defective wiring harness connecting temperature monitoring systems
• Blocked or damaged temperature sensor bulb preventing accurate readings
Precautionary measures
• Verify the refrigerator is plugged into a functioning outlet and the outlet has power by testing with another appliance
• Check that both the refrigerator and freezer doors are fully closed and sealing properly without gaps
• Ensure the appliance is level by using a bubble level on the front edge; adjust leveling feet if necessary
• Confirm temperature settings are configured correctly for your desired cooling levels
• Allow the refrigerator to stabilize for 4-6 hours after initial installation or following a power outage
• Inspect all visible vents and air circulation areas inside the refrigerator and freezer for ice buildup or obstructions and gently clear if blocked
• Verify the back of the refrigerator has adequate clearance (at least 2-3 inches) from walls for proper airflow
• Perform a power reset by unplugging the refrigerator from the wall outlet or switching off the dedicated circuit breaker for 60 seconds, then restore power
• Wait 15-20 minutes after power restoration for the control system to reinitialize
• Check the control panel display to see if the E1 error has cleared
• If the error code persists after these checks, contact a professional appliance repair technician or appliance repair support service to diagnose and repair the temperature sensor system
