Fridge troubleshooting guide – fast fixes for common cooling issues

Is your fridge warming up while the light stays on? You’re not alone. Most fridge hiccups are simple, cheap, and fixable without calling a technician. Below you’ll find the most common culprits and step‑by‑step actions you can take right now.

Common fridge problems and quick fixes

1. Door seal isn’t tight. A worn or dirty gasket lets warm air in. Check the seal by closing the door on a dollar bill; if it slides out easily, the gasket needs cleaning or replacement. Wipe it with warm soapy water, dry it, and test again.

2. Temperature setting is wrong. The dial may have been nudged during cleaning. Set the thermostat to the middle setting (usually 3 or 4) and give the fridge 24 hours to stabilise before adjusting further.

3. Condenser coils are dusty. Coils sit behind or underneath the fridge; dust blocks heat exchange, causing the compressor to overwork. Pull the fridge out, unplug it, and vacuum or brush the coils for a few minutes. Plug it back in and watch the temperature drop.

4. Frost buildup in the freezer. Too much frost makes the freezer work harder, pulling heat from the fridge compartment. Defrost manually by turning the fridge off, removing food, and letting ice melt. Clean and dry, then restart.

5. Overfilled fridge. Storing too much food restricts airflow. Rearrange items so that air can circulate freely, especially around the back where vents are located.

6. Faulty evaporator fan. If you hear a humming noise but no cooling, the fan may have stopped. Listen for the fan inside the freezer; a silent fan usually needs a replacement. This job often requires a screwdriver and a new fan motor.

7. Defective thermostat or temperature sensor. When the fridge stays warm even after cleaning and setting the dial, the sensor may be broken. Testing usually needs a multimeter, so if you’re comfortable with basic tools, replace the sensor; otherwise, move to the next step.

When to call a professional

If you’ve tried the above steps and the fridge is still warm, it’s time to get a pro. Common issues that need a qualified technician include a bad compressor, refrigerant leak, or electronic control board failure. These problems require special tools, refrigerant handling certification, and warranty considerations.

Call a local repair service, like Bognor Regis Appliance Repair Experts, and mention the symptoms you’ve observed. The more detail you give, the quicker they can diagnose and fix the problem.

Remember, regular maintenance—cleaning coils, checking seals, and defrosting when needed—keeps your fridge running efficiently and avoids costly repairs. A few minutes of DIY care each month can save you time, money, and the hassle of a broken fridge.
