Symptoms
• Refrigerator or freezer compartment not cooling properly or not reaching the correct temperature
• Error code E22 displayed on the digital control panel
• One or both compartments running warmer than normal settings
• Compressor running continuously or cycling irregularly
• Inability to adjust temperature settings on the display panel
• Audible beeping or alarm sounds from the unit
Possible Causes
• Faulty temperature sensor (thermistor) in the refrigerator or freezer compartment
• Loose or disconnected wire harness between the temperature sensor and control board
• Control board malfunction or loss of signal from the sensor circuit
• Damaged sensor probe or cracked sensor housing
• Electrical connection issue due to power fluctuations on the home circuit
• Failed evaporator fan motor preventing proper airflow and temperature regulation
• Defrost cycle malfunction affecting temperature accuracy readings
Safety Checks You Can Do
• Unplug the refrigerator for 60 seconds to perform a hard reset, then plug it back in to clear temporary sensor errors
• Check that the refrigerator is plugged into a dedicated 120V outlet and verify the outlet is functioning with another appliance
• Verify your home circuit breaker for the refrigerator circuit has not tripped; reset it if necessary
• Confirm the refrigerator is level on the floor using a spirit level, as improper leveling can affect sensor accuracy
• Inspect the door seals and gaskets on both the refrigerator and freezer compartments to ensure they are airtight and free of debris or damage
• Check that the refrigerator and freezer temperature settings are within the recommended USA range of 35-38°F for the fridge compartment and 0°F for the freezer compartment
• Remove any ice buildup or frost around the evaporator area visible through air vents inside the compartments
• Verify that air vents between the freezer and refrigerator compartments are not blocked by food items
• Inspect the condenser coils at the back or bottom of the unit for excessive dust buildup and gently vacuum if needed
• Ensure there is adequate clearance (at least 2 inches) on all sides of the refrigerator for proper airflow and ventilation
Safety First
Always disconnect the appliance from power before performing any checks. If you are unsure about any step, please contact a qualified technician.
