• Refrigerator not cooling properly or not cooling at all
• Freezer compartment warmer than normal (above 0°F)
• Fresh food section temperature rising above 40°F
• Food spoiling faster than usual
• F8 error code displayed on digital control panel
• Compressor running continuously without cycling off
• Unusual noises from compressor area
• Condensation buildup inside refrigerator

• Faulty compressor unable to maintain proper refrigerant pressure on 120V circuit
• Defective temperature sensor (NTC thermistor) providing incorrect readings
• Refrigerant leak in sealed cooling system
• Clogged capillary tube restricting refrigerant flow
• Failed start relay or capacitor on compressor motor
• Faulty electronic control board with inadequate 120V power regulation
• Broken or stuck damper control affecting air circulation
• Failed evaporator fan motor preventing cold air distribution
• Defective defrost timer or heater element causing ice blockage

• Check that the refrigerator is properly plugged into a grounded 120V outlet and verify the outlet has power using another device
• Inspect the circuit breaker controlling the refrigerator outlet—reset if tripped and monitor for repeat tripping
• Ensure the refrigerator is not pushed too close to walls; maintain at least 2-3 inches clearance on sides and back for proper ventilation
• Verify both refrigerator and freezer doors are closing completely and sealing tightly; check door seals for cracks or gaps
• Clean the condenser coils located at the bottom rear of the unit using a soft brush (unplug first if accessible without tools)
• Confirm temperature settings are correctly adjusted (typically 37-40°F for fresh food, 0°F for freezer)
• Remove any items blocking vents inside the refrigerator or freezer compartments
• Perform a hard reset by switching the circuit breaker off for 60 seconds, then switch back on and wait 5 minutes for system to restart
• Check that the defrost drain at the bottom is not clogged with ice or debris
• If error persists after these checks, contact a certified Miele service technician as internal repairs require specialized training and refrigerant handling certification
