Quick answer
A fridge that is not cooling usually has a temperature knob set too low, a door that does not seal, a dusty back coil with no space for air, or a problem with the compressor, fan, thermostat or gas. Check the setting, door gasket and space around the fridge first. If the light works but the compressor stays silent or the fridge stays warm for several hours, call a technician.
Signs you may notice
- Fridge light is on but food is not cold
- Freezer is cold but the lower fridge section is warm
- Milk and vegetables spoil faster than usual
- Compressor at the back is silent, or runs all the time
- Outer sides of the fridge feel unusually hot
Common causes (most likely first)
- 1
Wrong temperature setting
You can checkThe knob or display may have been turned to a low cooling level by mistake. After a change, give it a few hours to settle.
- 2
Door not closing or worn gasket
You can checkIf the rubber seal around the door is loose, torn or dirty, warm air keeps entering. Overfilled shelves can also stop the door from shutting fully.
- 3
No space for heat to escape
You can checkA fridge releases heat from its back and sides. Pushed tight against a wall, or placed near a stove or in direct sun, it struggles to cool.
- 4
Blocked air vents or too much ice (frost-free)
Needs technicianIn frost-free fridges, cold air flows from the freezer to the fridge through vents. If vents are blocked by food or ice, the lower section warms up.
- 5
Faulty thermostat, sensor or fan
Needs technicianThe thermostat or sensor tells the compressor when to run. The fan moves cold air around in frost-free models. If either fails, cooling stops or becomes uneven.
- 6
Compressor or relay problem
Needs technicianThe compressor is the heart of the cooling system. A failing relay or overload protector can stop it from starting, often after voltage fluctuations.
- 7
Gas leak
Needs technicianIf refrigerant leaks from a pipe, the compressor runs but nothing cools. The leak must be located and repaired before gas is recharged.
Safe checks you can do yourself
- 1Check the temperature knob or display and set it to a middle or recommended level. Wait 4–6 hours before judging.
- 2Close the door on a thin paper strip; if the paper slides out easily, the seal may be weak. Wipe the gasket clean with a damp cloth.
- 3Pull the fridge a few inches away from the wall so there is air space at the back and sides.
- 4Do not overpack shelves, and keep food away from the vents at the back of the fridge section.
- 5If a stabilizer is used, check it is switched on and giving output. Unplug for 5 minutes and plug back in once.
Always switch off and unplug the appliance before checking. Never open panels, touch wiring or try to refill gas yourself.
When to call a technician
- Fridge is still warm 6–8 hours after correcting settings and placement
- Compressor makes a click every few minutes but does not run
- Freezer is cold but the fridge section stays warm (frost-free models)
- Compressor runs non-stop yet nothing cools
- You notice a burning smell or the socket gets hot
FAQ
Frequently asked questions
Why is my fridge light on but not cooling?
The light only shows that power is reaching the fridge. The cooling parts — thermostat, relay, compressor, fan or gas — may still have a fault, so a technician should check it if basic checks do not help.
How long does a fridge take to cool after switching on?
Most fridges take a few hours to reach normal temperature, and the freezer may take longer. Avoid loading a lot of warm food during this time.
Why is my freezer cold but the fridge warm?
In frost-free fridges this often means the air vent between the freezer and fridge is blocked by ice, or the fan or defrost system has a fault.
Is it worth repairing an old fridge that is not cooling?
It depends on the fault. Problems like a relay, thermostat or gasket are usually worth fixing, while a compressor change on a very old fridge may not be. A technician can explain the options after checking.
