Fridge Not Cooling – Reasons and Our Solutions
A fridge not cooling is one of the most common calls we get at Best Fridge Repair Nairobi (Bestfridgerepair.co.ke). It’s a confusing fault because everything looks normal from the outside — the light comes on, the compressor hums, the door seals shut — yet the inside stays stubbornly warm. This kind of problem rarely appears out of nowhere. It usually builds up over weeks as one small component wears down, until the whole cooling cycle can no longer keep pace with what’s being asked of it.
Below is a breakdown of what typically causes this fault, what our technicians do to fix it, and what you can expect to pay for the repair or the parts involved.
What Usually Causes a Fridge Not Cooling
There are several reasons behind a fridge not cooling, and most of them trace back to one of a handful of components rather than the fridge as a whole failing at once.
- A struggling or worn compressor. The compressor drives the entire refrigeration cycle. If it’s weak, overheating, or has stopped starting altogether, cooling drops off noticeably.
- A refrigerant leak. Refrigerant doesn’t get “used up” under normal operation — if levels are low, gas is escaping somewhere along the sealed system.
- Dirty condenser coils. Coils covered in dust and grease can’t release heat efficiently, so the compressor works harder for a smaller cooling result.
- A faulty thermostat. If the thermostat isn’t reading the internal temperature correctly, it won’t tell the compressor to keep running when it should.
- A damaged door seal. A torn or loose gasket lets warm air creep in continuously, and the compressor never quite catches up.
- A failed evaporator or condenser fan. Without proper airflow, cold air can’t circulate evenly through the compartments.
- Overloading or poor airflow inside the unit. Packing shelves too tightly blocks vents and stops air from moving as it should.
How We Diagnose a Fridge Not Cooling
Because so many components can be responsible, we never guess or replace parts speculatively. A technician starts by checking the basics — power supply, thermostat setting, door seal condition — before moving on to testing the compressor’s start relay, checking refrigerant pressure, and inspecting the fans and coils. This structured approach means we usually identify the actual fault within the first visit, rather than replacing several parts one at a time to see what works.
Once the cause is confirmed, we explain it in plain terms and give an upfront quote before touching anything further. No work begins without your approval.

Keeping the Problem From Coming Back
A few simple habits go a long way toward preventing a repeat visit. Clean the condenser coils every few months, check the door seal for gaps by closing it on a sheet of paper and seeing if it slides out easily, avoid overpacking shelves, and give the fridge a few centimetres of clearance from the wall for airflow. None of this replaces a proper diagnosis when something has already gone wrong, but it does reduce how often a fault develops in the first place.
If your fridge is running warm, making unusual noises, or simply isn’t keeping food as cold as it used to, it’s worth having it looked at before the fault gets more expensive to fix. Small issues like a worn seal or a dirty coil are inexpensive to correct now and become costlier compressor problems later if left alone.
