Why Is My Fridge Not Cooling? 7 Common Causes Explained

A fridge that runs but isn't cooling is one of the most common appliance complaints we hear in Johannesburg. The good news: most causes are quick fixes.

Start with the condenser coils at the back or bottom of your fridge. A thick coat of dust forces the compressor to work harder and can cause the entire system to lose efficiency. Pull the fridge out, vacuum the coils and give the system a few hours to recover.

Next, check the temperature settings and the door seals. A worn gasket lets warm air in and your compressor never gets a break. A simple paper test — close the door on a sheet of paper and try to pull it out — will tell you if the seal is doing its job.

If the basics are in order, you may be looking at a faulty thermostat, a failing evaporator fan, or low refrigerant. These need a qualified technician with a multimeter and gauges. Don't attempt to recharge gas yourself — refrigerant work is regulated and dangerous.
