If your fridge runs but is not cold, check the temperature setting, make sure the door seals and vents are not blocked, and clean the condenser coils. If it is still warm, the evaporator fan, defrost system, relay or compressor may be at fault, which needs a technician.
When the fridge stops cooling properly, food spoils quickly and you cannot always tell the cause from the outside. Here are the eight most common reasons, in the order a technician would usually check them.
1. Temperature setting or mode
It sounds obvious, but a knob knocked to a warm setting, an “eco” or “holiday” mode, or a digital panel left in the wrong mode is a frequent cause. Set it to the recommended middle setting and wait several hours before judging.
2. Overpacked fridge or blocked vents
Cold air needs to circulate. Large containers pushed against the back wall, or food blocking the air vents, can leave parts of the fridge warm. Rearrange, keep gaps around vents and avoid stacking items directly over them.
3. Door not sealing properly
A cracked, dirty or stretched door gasket lets warm air in. Close the door on a sheet of paper. If the paper slides out easily, the seal is weak. Clean the gasket with warm water, and replace it if it is damaged. Also make sure the fridge is level and the door is not being held open by a bottle or tray.
4. Dirty condenser coils
The condenser coils release heat. Dust and pet hair make the fridge work harder, and it may run constantly without cooling well. With the fridge unplugged, clean the coils at the back or underneath with a soft brush or vacuum. Leave space around the fridge as recommended in your manual.
5. Evaporator fan not working
In frost-free refrigerators, a fan inside moves cold air from the freezer to the fridge. If it fails or ices up, the freezer may stay cold while the fridge section warms. A loud rattle, no fan noise, or a thick frost wall at the back are warning signs.
6. Defrost system problems
Frost-free fridges use a heater, timer and sensor to melt frost periodically. When this system fails, ice builds up around the evaporator and blocks airflow. Heavy ice at the back of the freezer is the classic sign. Defrosting the fridge fully may help temporarily, but the fault returns until it is repaired.
7. Thermostat, sensor or start relay
A failing thermostat or temperature sensor can give the wrong signals, and a faulty start relay or overload protector can stop the compressor from starting. You may hear a repeated click and then silence.
8. Compressor or refrigerant leak
If the compressor runs hot but the fridge is warm, or does not run at all, the sealed system may have a leak, a blockage or a failed compressor. These are the more serious faults and need proper diagnosis before any decision about repair or replacement.
Protect your food in the meantime
- Keep the door closed as much as possible.
- Move essentials to a cooler with ice.
- Discard perishable food that has been warm for more than about four hours, in line with general food-safety guidance.
When should you call a technician?
- You cleaned the coils and checked the seal and settings and it is still warm
- The compressor clicks or never starts, or runs constantly
- There is ice build-up at the back or water pooling inside or under the fridge
- You hear a loud rattle, buzz or grinding
Repair or replace?
If your fridge is under about 10 to 12 years old and the fault is a fan, sensor, relay or gasket, repair is normally good value. If it needs a compressor or sealed-system repair and the fridge is old, compare the cost with a new one. Our repair or replace guide can help.
