Refrigerator problems

When a fridge stops cooling or getting cold, the usual causes are:

• the evaporator fan motor, which moves cold air from the freezer coils into the fridge;
• the defrost system, which can let ice block the coils;
• a failed temperature sensor or control board telling the fridge it's already cold.

If the compressor runs but nothing gets cold, it can be the sealed cooling system.

A loud buzz is often the compressor struggling to start (a failed start relay). Grinding or squealing usually comes from the evaporator fan motor inside the freezer, sometimes catching ice, or the condenser fan motor near the compressor.

After putting in a new filter, press and hold the Filter Reset button for about 3 seconds until the light turns off. On many models, it's the Alarm button marked "Hold 3 sec for Filter Reset". On models with a touchscreen, reset it in the fridge settings. If the water still tastes bad or flows slowly, the usual causes are a filter that isn't fully seated, a failed water inlet valve, or a kinked water line.

On the floor, the usual causes are a failed water inlet valve, a cracked or loose water line, or a leaking ice maker. Inside the fridge, it's usually a frozen or clogged defrost drain.

Water under the crisper drawers usually comes from the defrost drain: when it freezes or clogs, melt water overflows into the fridge. A defrost heater or defrost control that has failed causes the same.

Heavy frost on the back wall usually means the automatic defrost isn't working: a failed defrost heater, a defrost control or timer, or the defrost sensor. A worn door seal letting in humid air adds to it.

When the setting is normal and food still freezes, the usual causes are an air damper stuck open, a temperature sensor reading wrong, or the control board.

Cold air reaches the fridge from the freezer, so the problem is usually on that path: an evaporator fan motor that has stopped, coils iced over because the defrost system failed, or an air damper stuck closed.

The usual part failures are the evaporator fan motor, the defrost system, and the freezer's temperature sensor. A worn door seal letting warm air in is the other usual cause.

Beyond spoiled food, the usual sources are water standing in a clogged defrost drain or the drain pan under the fridge, or an old water filter or ice bin.

Most fridges beep when a door is open too long or the temperature is too high. If the doors are closed, the usual causes are a door out of alignment or a worn gasket, a failed door switch, or a temperature alarm from a cooling problem.

On many Samsung fridges, ice builds up on the evaporator coils and blocks the fan when the defrost system fails. Other usual causes are the evaporator fan motor, or the inverter compressor's control board.

The usual causes are a defrost system that has failed (heater, sensor or control), an evaporator or condenser fan motor that has stopped, or a failed start relay on the compressor.

The usual causes are an evaporator fan motor, ice on the coils from a failed defrost system, or the compressor or its inverter control board.

If you can hear it running, the compressor may be trying to start but not managing to: often a failed start relay. A condenser fan motor that has stopped, or a problem in the sealed cooling system, gives the same symptom.

A fridge that never stops is usually working too hard: condenser coils clogged with dust, a condenser fan motor that has stopped, a worn door seal, or a sealed system low on refrigerant.

If the gasket is only twisted, warming it and pressing it back into shape can help. If it's torn, flattened or won't hold, the gasket needs replacing. A door that sags from worn hinges won't seal even with a new gasket.

Most refrigerator codes point to a fan, the defrost system, a temperature sensor, the ice maker, or the compressor. The same code means different things on different brands. See our refrigerator error codes page, or tell Switch the brand and the code.

Usually yes when the problem is a fan, sensor, defrost part, valve or control board. A failed compressor or a refrigerant leak on an older fridge is when replacing often makes more sense. Your diagnostic report shows which it is.

Start with what it does:

• Not cold: fans, defrost or sensor.
• Leaking: water valve, water line or defrost drain.
• Noisy: fans or start relay.
• Freezing food: air damper or sensor.
• Beeping: door alignment or a temperature alarm.
