Absolute Defy Fridge Not Cooling? The Faults We Fix Most
Same-day service On-site repair Call 072 686 0472
Defy fridges are in a huge number of South African kitchens, and we repair them every week. When a Defy stops cooling, the cause usually depends on the type: a simple static fridge with a thermostat, a frost-free fridge with a fan and defrost system, or a side-by-side with electronic controls. Here is what we find most, from our own Defy repairs across Gauteng.

The most common reasons a Defy fridge stops cooling are a gas leak or blockage in the sealed system (often the freezer stays cold while the fridge warms up), a faulty thermostat, a compressor that is running but not pumping, a failed fan on frost-free and side-by-side models, and control board faults on electronic models. Check the thermostat setting, that the door seals close properly and that there is space behind the fridge first. If it is still warm, it needs testing. Absolute Repairs repairs Defy fridges on site across Gauteng, including Pretoria: flat R350 call-out, waived if we do the repair.
First, a few quick checks
- The thermostat dial or setting. On many Defy fridges the thermostat is a simple dial inside the fridge. It is easy to knock it to a warmer setting when packing food.
- Door seals. Close the door on a piece of paper. If it slides out easily, the seal isn't sealing and warm air is getting in.
- Space and heat. The fridge needs to get rid of heat through the back or sides. Pushed tight against a wall, next to a stove or with things piled on top, it struggles, especially in summer.
- Listen. Is the compressor at the bottom back running? Is it much louder than usual, clicking on and off, or silent?

The faults we fix most on Defy fridges
1. Freezer cold, fridge warm: a gas leak or blockage
On many Defy fridge-freezers the gas cools the freezer first and then the fridge. When the system is low on gas or partly blocked, the freezer can stay cold while the fridge never gets cold. On a Defy fridge-freezer in Greenstone Hill with exactly this fault, our technician repaired the sealed system on site, brazing the pipework at the compressor, then recharged it with gas until both sections were cooling.
2. Loud and not cooling: the compressor
The compressor is the pump that circulates the gas. When it wears out, it can keep running without pumping, so nothing gets cold, and it is often louder than usual. A Defy side-by-side in Halfway House was loud and not cooling: the compressor was running but not pumping. We replaced it, brazed in the new one and recharged the system, and it was cold and quiet again.
3. Thermostat faults
On static Defy fridges, the thermostat tells the compressor when to run. If it fails, the fridge can stop cooling, or the opposite: run non-stop and freeze everything. Thermostats are an affordable repair.
4. Fans on frost-free and side-by-side models
Frost-free Defys use a fan to move cold air around. A failed or damaged fan means poor cooling, and often a new noise first. On a Defy side-by-side in Mooikloof, Pretoria East, an unusual noise turned out to be a broken fan blade. We replaced it the same day.
5. Control boards on electronic models
Many Defy side-by-sides use electronic controls, and some use Samsung-made boards. A board fault can make the fridge click, run erratically or go dead while the light still works. On a Defy side-by-side in Johannesburg South, we traced the fault to the main control board and replaced it.
A board isn't always the answer, though. The compressor, fans and sensors need testing first, so you don't pay for a board you don't need.
Repair or replace?
Most Defy fridge faults are well worth repairing: thermostats, fans, relays, boards and leak repairs usually cost far less than a new fridge. A compressor replacement on an old, tired fridge is the main case where buying new can make more sense, and we'll tell you honestly. See repair or replace for more.

Recent job: Defy fridge with a faulty relay and overload
Defy side-by-side not cooling: compressor not running, relay and overload replaced
The customer in Sandton called because the freezer side of their Defy side-by-side had stopped getting cold, but they thought the fridge side was still fine. When we checked, neither side was actually cold: the fan was still blowing air into the fridge, which felt cool on the hand, but the compressor wasn't running at all. We traced that to a faulty start relay and overload, the small parts on the side of the compressor that help it start and protect it from overheating. We replaced them, fitted a new filter drier, and gave the fridge a service while the system was open. The display was back to −18 °C in the freezer and 4 °C in the fridge. Tip: air blowing out of the vents doesn't mean a fridge is cooling. If food is going soft, check whether the compressor at the bottom back is running. If it is silent, or clicks every few minutes without starting, the start relay is a common cause.
Frequently asked questions
Why is my Defy fridge not cooling but the freezer is cold?
On many Defy fridge-freezers the gas cools the freezer first, so a gas leak or partial blockage can leave the freezer cold while the fridge warms up. On frost-free models, a failed fan or iced-up air path can do the same. It needs testing to find which.
Why is my Defy fridge making a loud noise and not cooling?
A compressor that is running but no longer pumping is often louder than usual and gives no cooling. A damaged fan blade can also make a new noise. Switch the fridge off and get it checked before the compressor overheats.
Can a Defy fridge thermostat be replaced?
Yes. On static Defy fridges the thermostat is a common and affordable repair, whether the fridge has stopped cooling or is freezing everything.
