Refrigerator Not Cooling? A Symptom-by-Symptom Cost Guide (2026)

The most useful diagnostic for a fridge that is not cooling is to open both compartments and feel them separately. Whether the freezer is still cold or has warmed up too tells the technician - and you - roughly where the fault is and what it will cost, before anyone opens a panel.

A partial-cooling fridge (freezer fine, fridge warm) is usually a cheaper airflow fault. A whole-fridge failure (both warm) is the one that can involve gas or the compressor.

Freezer cold but fridge section warm

This is the reassuring case. The system is still making cold, but it is not reaching the fridge compartment - an airflow problem. The usual causes are a failed evaporator fan, a clogged defrost system icing up the vent, or a door left ajar. On frost-free models a defrost timer or heater fault is common.

These are mid-range repairs, roughly 800 to 2,500, and importantly they do not involve the expensive gas-and-compressor circuit. If a technician jumps straight to gas on a fridge whose freezer is clearly still working, ask why.

Whole fridge warm - the gas-versus-compressor question

When both compartments are warm and the compressor is silent or humming without cooling, you are into the sealed system: either the refrigerant has leaked out, or the compressor has failed. Telling them apart needs a technician, and it matters enormously because a gas recharge with leak repair is a fraction of a compressor replacement.

A good diagnosis checks for a leak and tests the compressor before quoting. Because the compressor is the costliest part (and often under a long warranty), never accept a compressor verdict without the gas and electrical checks shown to you first - and always check the warranty card.

Compressor running constantly

A fridge whose compressor never switches off is struggling to reach temperature - usually low gas, or, very commonly and cheaply, condenser coils at the back caked in dust so heat cannot escape. Cleaning the coils is a near-free fix that solves a surprising number of over-working-fridge and high-bill complaints.

Rule out the coils and door seal before assuming anything internal.

Water pooling and door seals

Water inside the fridge or on the floor is usually a blocked defrost drain - a cheap clear-out - not a cooling fault, though a heavily iced system can cause both. A warm fridge combined with a door that no longer snaps shut points to a perished gasket letting warm air in; a gasket replacement restores the seal and the cooling.

What to do next

Feel both compartments, note which are warm, and match the symptom to the table before booking - it steers the technician to the right check and keeps the quote honest.
