Many fridge problems have simple causes and solutions. This troubleshooting guide covers the most common fridge issues Australian households encounter and what to do about them.
Fridge Not Cold Enough
Check first:
- Temperature setting — set between 3–5°C for the fridge, -18°C for freezer
- Door seals — place a piece of paper in the door and close it. If it slides out easily, the seal is failing
- Coils behind or underneath — dust on condenser coils reduces cooling efficiency significantly. Vacuum them every 12 months
- Clearance — fridges need 50mm minimum clearance on sides, 100mm on top and back for air circulation
- Overfull fridge — packing the fridge too tight blocks air circulation
When to call a technician: If the compressor isn't starting (you can hear it cycle or feel vibration), or if the fridge is old and simply can't hold temperature in Sydney summer heat, it may be the compressor or refrigerant system. These require a licensed technician.
Fridge Making Noise
Normal sounds: Clicking (thermostat cycling), humming (compressor), gurgling (refrigerant moving), crackling (plastic components expanding and contracting with temperature changes).
Sounds to investigate:
- Loud buzzing: Often the evaporator fan hitting ice. Defrost the fridge manually.
- Rattling: Check items on top of the fridge. Also check the drip tray underneath isn't vibrating.
- Grinding or loud knocking: Compressor issues. Have a technician assess it.
Water Pooling Inside the Fridge
Likely cause: Blocked defrost drain. The drain tube that carries defrost water from the freezer to the drip tray gets blocked with ice or debris.
Fix: Locate the drain hole inside the fridge/freezer (usually at the back bottom). Use a turkey baster or a thin flexible brush to clear the blockage. Flush with warm water.
Frost Buildup in Freezer
Modern fridges are frost-free, so significant frost buildup indicates a problem:
- Door not sealing properly — check door seals (see above)
- Defrost heater or thermostat failure — requires a technician
Manual defrost fridges (older models) require periodic manual defrosting — this is normal.
Fridge Not Turning On
- Check the power outlet is working (plug in another appliance)
- Check the circuit breaker hasn't tripped
- Check the temperature controls aren't turned to "Off"
- Try unplugging for 5 minutes and replugging (soft reset)
Ice Maker Not Working
- Confirm the ice maker arm is in the down (on) position
- Check the water supply line is connected and the valve is open
- Water filter: a blocked or old filter reduces water flow. Replace every 6 months
- Ice maker harvest arm stuck in ice: defrost gently with a hairdryer
When Repair Doesn't Make Sense
For fridges over 10 years old with compressor or sealed system failure, repair often costs more than the fridge is worth. At Oceania Appliances, we have certified refurbished premium fridges from $299 with 3-month warranty — often the more economical choice than a major repair on an aging fridge.
