A refrigerator is a household appliance that keeps food fresh by maintaining a low, stable temperature. It removes heat from the compartments using a refrigeration system (compressor, evaporator, condenser) and regulates operation through sensors and a thermostat or electronic control module.
A freezer is designed for long-term storage at much lower temperatures, typically around −18 °C (0 °F) or below. Freezers come as upright cabinets or chest models, built-in or freestanding. Many units use No Frost technology to reduce ice buildup and simplify maintenance.
Typical faults and what to do:
-
Not cooling / weak cooling: check the power supply and temperature settings - make sure vents inside are not blocked by food - clean condenser coils and ensure space for ventilation around the unit.
-
Freezer cold but fridge warm: check that air vents between compartments are open, if the evaporator fan is not running or there is heavy frost behind the rear panel, the defrost system (heater, sensor, timer/control) may need service.
-
Excessive frost or ice: verify the door closes tightly - inspect and clean the door gasket, replace it if torn or deformed; limit door-open time, if No Frost still ices up, a defrost fault is likely.
-
Water leaking inside or onto the floor: clean the drain hole and drain channel - check the drip tray and that the appliance is level; ensure the door gasket seals properly to prevent condensation.
-
Loud noise or vibration: level the appliance and keep it from touching walls/furniture - check for loose shelves or items; persistent grinding or buzzing can indicate a fan or compressor issue.
-
Runs constantly / high electricity use: clean condenser coils - check gasket sealing; avoid overloading and hot food inside, if it still runs nonstop with poor cooling, sealed-system or sensor/control problems are possible.
Safety note: unplug the appliance before cleaning or inspecting parts. Work on the sealed refrigeration circuit (refrigerant leak, compressor replacement) should be done by a qualified technician.
