The compressor is the heart of any fridge or freezer — it's what actually moves refrigerant through the system and keeps things cold. When it starts to fail, it rarely happens without warning. Catching the early signs can be the difference between a same-day repair and a full replacement.
1. It's louder than it used to be. A healthy compressor hums quietly in the background. A knocking, clicking, or noticeably louder buzzing sound often means internal components are wearing out.
2. It's running constantly. Compressors cycle on and off to maintain temperature. If yours seems to run non-stop, it may be struggling to keep up — often the first sign of reduced efficiency.
3. The fridge feels warm to the touch. Some warmth near the back or sides is normal. Excessive heat, especially combined with a hot compressor housing, points to it working harder than it should.
4. Food isn't staying as cold. If your milk is turning sooner than usual or ice cream is softer than it should be, the compressor may not be maintaining pressure properly.
5. It won't start at all, or starts and stops immediately. This is usually the final stage — a failed start relay or a seized compressor.
If you're seeing two or more of these, it's worth getting it looked at before it fails on a Friday night with a fridge full of food. We diagnose and repair on-site across Durban and Queensburgh.
