It quietly works around the clock to keep your food fresh, drinks cold, and ice cream scoop able. But like all machines, it can develop issues over time.
Because it runs continuously — and because Australian summers can be extremely hot — problems tend to show up quickly and dramatically causing common fridge problems.
This guide explores the most common fridge problems in Australian homes, how you can troubleshoot simple issues yourself, and clear signs you should call a professional technician.
Why Prompt Attention Matters in Common Fridge Problems
When a fridge starts acting up, it’s not just inconvenient — it can lead to spoiled food, increased energy bills, moisture problems, and even safety hazards. In Australia, where temperatures can soar in summer and humidity can affect performance, maintaining
g your fridge is especially important. Some issues are simple to fix at home, but others require a licensed technician, especially when refrigerant or electrical systems are involved.
1. Fridge Not Cooling (or Freezer Warm) that are common fridge problems
Symptoms
-
Food in the fridge or freezer is warm.
-
Ice cream is softened.
-
The compressor runs continuously.
Common Causes
-
Dirty condenser coils
-
Blocked vents or airflow
-
Faulty thermostat
-
Damaged door seal
-
Low refrigerant (leak)
DIY Checks & Fixes
-
Check the thermostat: Ensure the temperature settings haven’t been accidentally turned up.
-
Clean the condenser coils: These are usually at the back or underneath the fridge. Dust buildup prevents proper heat exchange.
-
Clear vents inside the fridge: Food items blocking internal vents restrict air circulation.
When to Call a Professional
If cleaning and simple checks don’t restore cooling — especially if the compressor is unusually hot or noisy — call an authorized fridge technician. Refrigerant systems require licensed professionals in Australia due to safety and environmental regulations.
2. Fridge Freezing Food in the Fridge Compartment
Symptoms
-
Soft vegetables or drinks freeze in the fridge section.
-
Unexpected frost appears.
Common Causes
-
Faulty thermostat or temperature sensor
-
Airflow imbalance
DIY Checks & Fixes
-
Check and reset the temperature to the manufacturer’s recommended setting.
-
Move items away from air vents to improve airflow.
When to Call a Professional
If the problem persists after DIY checks, or the temperature control seems malfunctioning, contact a fridge technician.
3. Excessive Frost or Ice Build-Up
Symptoms
-
Thick ice on freezer walls.
-
The fridge cycles on and off frequently.
Common Causes
-
Defrost system failure (heater, thermostat or timer)
-
Door left open often
-
Worn door seal
DIY Checks & Fixes
-
Clean door seals and check for gaps.
-
Manually defrost by turning off the fridge and letting the ice melt.
-
Ensure doors are fully closing each time.
When to Call a Professional
If frost returns rapidly after manual defrost or if you suspect internal defrost system components are failing.
4. Water Pooling or Leaking
Symptoms
-
Water puddles around the fridge.
-
Moisture in drawers.
-
Water under the fridge.
Common Causes
-
Blocked drain tube or hole
-
Defrost water overflowing from tray
-
Issues with ice maker or water dispenser (in models with water/ice)
DIY Checks & Fixes
-
Locate and clear the drain hole — warm water can help flush blockages.
-
Check the water filter and replace if needed (for models with dispensers).
When to Call a Professional
If the leak source isn’t obvious, persists, or involves internal plumbing and valve systems.
5. Strange Noises (Buzzing, Clicking, Loud Humming) in common fridge problems
Symptoms
-
New or louder-than-usual noises.
-
Buzzing, rattling, or thumping sounds.
Common Causes
-
Obstructed fan blades
-
Loose items touching internal parts
-
Failing compressor or faulty start relay
DIY Checks & Fixes
-
Move the fridge slightly away from the wall to improve airflow.
-
Remove items touching fans or internal panels.
When to Call a Professional
Persistent or unusual noises — especially metallic knocks or sounds that accompany performance issues — need a technician’s inspection. Compressors and electrical parts aren’t DIY fixes.
6. Fridge Runs Constantly (High Energy Use)
Symptoms
-
The fridge never seems to switch off.
-
Higher energy bills.
Common Causes
-
Dirty coils
-
Poor door seal
-
Overstuffed interior
-
Faulty thermostat or compressor
DIY Checks & Fixes
-
Clean condenser coils.
-
Check and clean door gaskets.
-
Avoid placing the fridge near heat sources.
When to Call a Professional
If it continues to run excessively despite maintenance, have an appliance tech test key components.
7. Bad Smells or Mold
Symptoms
-
Persistent odours even after cleaning.
-
Visible mould in drawers, corners, or seals.
Common Causes
-
Spilled or forgotten food
-
Blocked drain or drainage tray
-
High humidity buildup
DIY Checks & Fixes
-
Empty the fridge and thoroughly clean the interior with warm, soapy water or baking soda solution.
-
Wash drawers and shelves.
-
Pull out and clean the drain pan under the fridge.
When to Call a Professional
If mould returns quickly or if smells seem to come from hidden internal plumbing or mechanical areas.
8. Door Not Sealing Properly
Symptoms
-
Condensation around the door.
-
Warm edges despite internal cooling.
-
Frequent cycling on/off.
Common Causes
-
Worn door gasket
-
Misaligned hinge
-
Warped door
DIY Checks & Fixes
-
Clean the gasket and check for gaps using a piece of paper — it should resist pulling out when the door is closed.
-
Tighten hinge screws if misalignment is minor.
When to Call a Professional
If the gasket needs replacing or if significant misalignment is evident.
When to Call a Professional — Quick Checklist
-
Refrigerant concerns or suspected leaks.
-
Unusual electrical behaviour (fuses blowing, burning smells).
-
Persistent water leaks.
-
Compressor problems.
-
If the fridge is under warranty (contact the authorised service centre to avoid voiding it).
-
If you’re uncomfortable performing basic checks — especially around the back of the fridge where sharp fins and electrical components are common.
Local Notes for Australian Homeowners
-
In Australia, handling refrigerants legally requires a licensed technician — never attempt it yourself.
-
High summer temperatures in many regions mean fridges work harder and have less margin for error.
-
Tax savings and energy rebates often make updating to a new energy-efficient fridge worthwhile, especially if your unit is over 10 years old.
-
Keep model and serial numbers handy when booking a service — it speeds up diagnosis and warranty claims.
Simple Preventative Tips
-
Clean condenser coils twice a year.
-
Check door seals regularly.
-
Avoid overloading the fridge — allow airflow around food.
-
Position the fridge away from direct sunlight, ovens, or heaters.
-
Defrost occasionally before frost becomes problematic.
Conclusion
Common fridge issues — from cooling problems to strange noises — often have straightforward DIY fixes. However, certain problems involving refrigerants, compressors, or internal electrical systems require a licensed technician. Acting early helps prevent food spoilage, reduces energy bills, and extends your fridge’s lifespan.
FAQs
Q: Can I top up the refrigerant myself?
No — in Australia, refrigerant work must be carried out by licensed technicians due to safety and environmental laws.
Q: How often should I service my fridge?
A basic clean and check twice a year is good; professional servicing every 2–3 years keeps it efficient.
Q: My fridge is 12 years old — should I repair or replace it?
If the repair cost is close to half the price of a new, energy-efficient model — or if energy use is high — replacement is often a better long-term choice.
