A fridge that's not cooling properly can mean anything from a minor, five-minute fix to a part that needs replacing. Before assuming the worst, it helps to understand what's actually likely to be going wrong.
Start with the basics
- Temperature setting: It sounds obvious, but a dial accidentally nudged to a warmer setting is a very common cause.
- Overloading: Packing the fridge too tightly blocks air circulation between shelves, so some areas stay warm even though the compressor is working fine.
- Door seal: A worn or loose door gasket lets cold air escape constantly. Close the door on a piece of paper - if you can pull it out easily, the seal needs replacing.
More likely technical causes
If the basics check out and cooling is still weak or absent, the issue is usually one of these:
- Low refrigerant (gas) levels due to a slow leak - cooling gradually gets worse over weeks
- A faulty condenser fan or compressor - often comes with unusual humming or complete silence where there should be a running motor
- Blocked or frosted-over evaporator coils - common in older single-door and double-door models
- A failing thermostat that isn't signalling the compressor to run correctly
When to call a technician immediately
If food has already started spoiling, there's a burning smell, or the compressor is running constantly without ever cooling down, stop trying to diagnose it yourself and get a technician in - continuing to run a fridge with a failing compressor can turn a repair into a full replacement.
