How to Tell If Your Fridge Is Not Cooling Properly
A fridge that's not cooling properly can silently spoil your food before you notice. Knowing the warning signs early can save you from food waste, illness and potentially a costly repair or replacement. Here's what to watch for.
Signs Your Fridge Is Not Cooling Properly
1. Food Is Spoiling Faster Than Normal
If your milk, fresh produce or leftovers are going off noticeably faster than usual, it's a sign your fridge temperature has risen. This is often the first sign people notice.
2. The Fridge Feels Warm Inside
Open the fridge and feel the air. It should feel consistently cool. If it feels less cold than usual or even slightly warm in areas, the cooling system is struggling.
3. Condensation Inside the Fridge
Excessive moisture or water droplets inside the fridge can indicate a door seal issue (warm air getting in) or a problem with the defrost cycle.
4. The Fridge Is Running Constantly
Fridges cycle on and off automatically. If the compressor is running constantly (you can hear the hum never stopping), the fridge may be struggling to reach its set temperature.
5. Ice Cream Is Soft in the Freezer
Ice cream that's soft or slushy in the freezer is a clear sign the freezer section isn't cold enough. This may also affect the fridge compartment.
6. Frost Buildup in the Freezer
Excessive frost buildup in the freezer can restrict airflow to the fridge section. If your freezer has thick frost on the walls, it needs defrosting.
Quick Checks to Do First
- Check the temperature settings: Has the temperature dial been accidentally turned down? Set the fridge to 3–4°C and freezer to -18°C.
- Check the door seals: Run your hand around the door seal — if you feel cold air escaping, the seal may be damaged. Test by closing the door on a piece of paper — if the paper slides out easily, the seal isn't gripping.
- Check air vents inside the fridge: Are vents blocked by overfilled shelves? Proper airflow inside the fridge is important.
- Check the condenser coils: Dusty condenser coils (usually at the back or bottom of the fridge) reduce cooling efficiency. Vacuum them gently if accessible.
- Check clearances: Is the fridge getting enough ventilation? Top, sides and back all need clearance as per the manufacturer spec.
Common Causes of a Fridge Not Cooling
- Faulty door seal (most common fixable cause)
- Dirty condenser coils
- Faulty evaporator fan motor (circulates cold air inside the fridge)
- Faulty defrost heater (causes frost buildup that blocks airflow)
- Low refrigerant (requires a licensed technician)
- Failing compressor (most expensive repair; may warrant replacement if older)
When to Call a Technician
If basic checks don't resolve the issue, call a licensed appliance technician. They can diagnose refrigerant, compressor and electrical faults that require specialist tools.
When to Replace
If your fridge is more than 10 years old and needs a major repair, replacement is often more economical. Modern fridges are significantly more energy efficient than older models.
