If your freezer is still cold but your fridge compartment has stopped cooling, the problem is usually caused by restricted airflow, a faulty evaporator fan, a blocked defaporst system or a failed thermostat. In many cases, the compressor is still operating normally, making the issue repairable without replacing the entire refrigerator. Selective Fridges provides mobile fridge repairs throughout Perth, diagnosing the fault on-site and helping get your fridge back to the correct temperature as quickly as possible.
Nothing is more frustrating than opening your fridge to find warm milk, soft butter and food that is no longer safe to eat, only to discover the freezer is still keeping everything frozen.
This is actually one of the most common refrigerator problems our technicians see across Perth.
The good news is that because the freezer is still operating, there’s a strong chance the refrigeration system itself is working. The fault is often isolated to one component that prevents cold air from reaching the fridge compartment.
What This Fault Usually Means
Most modern frost-free refrigerators produce all of their cold air inside the freezer.
A fan then circulates that cold air into the refrigerator section through a series of vents and ducts.
If anything interrupts this airflow, the freezer may continue operating perfectly while the fresh food compartment gradually becomes warmer.
That is why a freezer can remain at the correct temperature while everything in the fridge starts spoiling.
The Most Common Causes
1. Faulty Evaporator Fan
The evaporator fan is responsible for moving cold air from the freezer into the fridge.
If this fan stops working, the freezer often remains cold while very little cold air reaches the refrigerator section.
Typical signs include:
- Warm fridge
- Cold freezer
- Little or no airflow from internal vents
- Unusual humming or clicking sounds
2. Blocked Air Vents
Boxes, containers or excessive ice build-up can block the vents that carry cold air into the refrigerator compartment.
Even partially blocked vents can dramatically reduce cooling performance.
This is one of the simplest issues to diagnose and sometimes the easiest to resolve.
3. Defrost System Failure
Modern frost-free refrigerators automatically melt away frost several times each day.
If the defrost heater, timer or sensor fails, thick ice can accumulate around the evaporator coils.
Eventually, the ice blocks airflow entirely, leaving the freezer cold while the fridge becomes warm.
4. Thermistor or Temperature Sensor Problems
The refrigerator relies on sensors to determine when cooling is required.
A faulty sensor may send incorrect information to the control board, preventing the refrigerator compartment from cooling properly.
5. Damaged Door Seals
If warm air constantly enters the refrigerator through worn door seals, cooling efficiency drops significantly.
While this alone doesn’t always cause the freezer-to-fridge temperature difference, it can make the problem much worse.
Can You Check Anything Yourself?
Before arranging a repair, there are a few simple checks you can safely carry out.
- Make sure nothing is blocking the internal air vents.
- Check that both doors close properly.
- Listen for the evaporator fan when the freezer door is closed.
- Look for excessive frost or ice build-up inside the freezer.
- Confirm the temperature settings haven’t been accidentally changed.
If these checks don’t identify the issue, it’s best to have the appliance professionally diagnosed before further damage occurs.
What Happens If You Ignore the Problem?
Continuing to use a refrigerator that isn’t cooling properly can lead to:
- Spoiled food
- Increased electricity consumption
- Greater strain on refrigeration components
- Damage to electronic parts
- More expensive repairs if left unresolved
Early diagnosis often prevents a relatively minor issue from becoming a major repair.
When Should You Call a Technician?
If your freezer remains cold for several hours while the fridge continues warming, professional diagnosis is recommended.
Mobile technicians have specialised equipment to test fans, sensors, electronic control boards, compressors and defrost systems without unnecessary guesswork.
Identifying the correct fault the first time usually results in faster repairs and lower overall costs.

Frequently Asked Questions
Can a fridge be repaired if the freezer still works?
Yes. In many cases the refrigeration system is still functioning correctly, and the problem is related to airflow, sensors or the defrost system.
Is it safe to keep using the fridge?
No. Food stored above safe temperatures can spoil quickly, even though the freezer remains cold.
How long does it take to diagnose the problem?
Most faults can be diagnosed during an on-site visit by an experienced technician.
Can blocked vents stop the fridge cooling?
Yes. Restricted airflow is one of the most common causes of this fault.
Should I unplug the refrigerator?
If excessive ice build-up is present, unplugging the appliance may help prevent further damage until it can be inspected. However, it’s still important to arrange a professional diagnosis.
