"My fridge has run out of gas" is one of the most common explanations people hear, and often one of the least accurate. A refrigerator's cooling system is sealed, and a true leak is relatively uncommon. Several simpler faults produce very similar symptoms, which is why a proper diagnosis matters before anyone talks about refilling anything.
What a real refrigerant problem looks like
When a sealed system loses refrigerant or becomes blocked, you may see:
- Poor cooling in both the fridge and the freezer
- A compressor that runs but the evaporator does not get properly cold
- Frost forming only on part of the evaporator
- A compressor that runs for long periods with little effect
- An oily residue at a joint or tube, in some cases
Even then, these signs are not proof. They need to be measured and confirmed by a technician.
Look-alike faults
A failed evaporator fan
The freezer may still be cold, but air is not circulated into the fridge. The fridge section is warm.
A defrost fault
Ice blocks the airway and chokes cooling. The fridge may cool again after a manual defrost, then fail again.
A dirty condenser
The system cannot shed heat, so cooling is poor and the compressor runs long.
A worn door seal
Warm air enters, causing weak cooling and frost.
A faulty temperature sensor or control board
The fridge may switch cooling off too early or not run when it should.
A failing start relay or compressor
The fridge may click, hum or not start at all.
Safe checks you can make
- Check that the plug, socket and settings are right.
- Look at the door seals.
- Check that the fridge has ventilation, and that the back is not extremely hot.
- Check for ice on the back wall of the freezer.
- Note if the compressor runs, clicks or stays silent.
None of these needs panels removed.
How a technician confirms it
A technician checks the simple causes first, observes how the fridge behaves, tests the fans, defrost parts and electrical components, and examines the sealed system. Only if the evidence points to a refrigerant-side fault do they discuss that repair. Sealed-system work is specialist work, and in some cases the age of the fridge makes repair less sensible. We explain options honestly. See refrigerator repair.
Why it matters
Being told "it needs gas" when the real fault is a fan or a seal means paying for the wrong repair, and the fault returns. A clear diagnosis protects you. For more typical faults, see common fridge faults in hot, humid climates. If your fridge has stopped cooling completely, read when a fridge fault is an emergency.

Frequently asked questions
Do fridges need regular gas refills?
No. The system is sealed and should not need topping up. Needing it suggests a leak.
Can I tell a leak from a dirty condenser at home?
Not reliably. A dirty condenser is easy to spot and clean; otherwise a technician can measure.
Is a refrigerant leak dangerous?
Small leaks in a ventilated kitchen are usually low risk, but some refrigerants are flammable, so avoid sparks and call a technician.
Is it worth repairing a leaking old fridge?
It depends on the age, cost and condition. We will give you an honest comparison.
