Fridge not cold enough — what to check tonight
Thermostat settings, condenser coils, door gaskets. Includes food-safety guidance for perishables.
Safety first — do not use the appliance
If you smell gas, call the National Gas Emergency Service on 0800 111 999. For immediate danger call 999.
This professional guide has been compiled by the Kettlebridge engineering team to help you diagnose and, where safe, resolve common appliance issues. We provide these steps based on thousands of successful repairs across the UK.
Follow the troubleshooting steps below in order. Remember: safety is paramount. If you encounter any step that involves live electricity, gas connections, or complex disassembly that you are not comfortable with, stop immediately and contact a professional.
Step-by-step checks
- Confirm the temperature setting. Fridge: 3–5°C. Freezer: -18°C. Check with a fridge thermometer.
- Give the coils some space. Fridges pushed flush to a wall can overheat. Leave 5cm clearance at the back.
- Vacuum the condenser coils. Dust on the back or beneath causes overheating and poor cooling.
- Check the door seals. Same paper test as above.
Safety notes
- If perishables have been above 8°C for 4+ hours, discard high-risk foods (dairy, meat, cooked rice).
When to book a repair
If settings and airflow are correct but the fridge won't hold temperature, the compressor or thermostat needs professional diagnosis.
