Symptoms
• Refrigerator compartment not cooling to the desired temperature
• Freezer section cooling normally while fridge section remains warm
• Error code E23 displaying on the digital control panel
• Audible clicking or humming sounds from the back of the unit
• Ice buildup or frost in unusual locations within the fridge
• Compressor running continuously without cycling off
• Food spoiling faster than normal
Possible Causes
• Faulty refrigerator compartment temperature sensor (thermistor) unable to send accurate readings
• Evaporator fan motor malfunction preventing airflow to fresh food section
• Frozen or obstructed evaporator coils blocking cold air distribution
• Loose or disconnected wiring harness between control board and temperature sensor
• Failed defrost timer causing ice accumulation on evaporator
• Control board malfunction preventing proper signal interpretation from sensor
• Airflow damper stuck in closed position reducing airflow to fridge section
Safety Checks You Can Do
• Perform a hard reset by unplugging the refrigerator from the 120V outlet for 60 seconds, then plug it back in and observe if the error clears
• Verify the refrigerator is on a dedicated 120V/60Hz circuit breaker and not sharing power with other appliances
• Check that the home circuit breaker for the refrigerator has not tripped; reset if necessary
• Ensure all refrigerator and freezer compartment doors close completely and the door seals are airtight with no visible gaps or cracks
• Verify the refrigerator is level on the floor using a level tool, as improper leveling can affect cooling performance
• Inspect the condenser coils at the back or bottom of the unit for excessive dust buildup and gently vacuum if needed
• Check the internal temperature settings and adjust to the recommended USA range of 35-38°F for the refrigerator compartment and 0°F for the freezer
• Confirm the vents inside the refrigerator compartment are not blocked by food items or containers
• Allow 24 hours for the unit to stabilize after a hard reset before determining if service is needed
