Why Your Refrigerator Stops Cooling (and How to Fix It)

When a refrigerator stops cooling, the most common causes are a gas (refrigerant) leak, a failing compressor, a faulty thermostat or a blocked defrost system. Each has different symptoms, so an accurate on-site diagnosis matters.

Start with the easy checks: confirm the unit has power, the door seals fully, and the vents inside aren't blocked by food. If the freezer works but the fridge section is warm, the problem is often airflow or the defrost system rather than the compressor.

A leaking refrigerant circuit or a burnt-out compressor needs a qualified technician — refrigerant handling and compressor replacement are not DIY jobs. We locate the leak, repair it, refill with the correct gas and verify stable cooling before we leave.

Our technicians service domestic and commercial refrigerators and freezers of all major brands, using genuine parts. If a repair isn't worthwhile, we'll tell you honestly rather than sell you an unnecessary fix.

The best protection against a mid-week breakdown is preventive care — an Annual Maintenance Contract keeps seals, gas levels and cooling performance in check all year round.
