Fridge not cooling

likely causes and what to check

What it means

A warm fridge is an emergency for the food, but the causes are often cheap: dust, ice, or a part under $100. Start with the simple ones before assuming the worst.

Two checks here are free and settle most cases. Anything touching the refrigerant itself is a stop line — the page says so plainly.

Likely causes, ranked

Condenser coils dirtydust on the coils under or behind the box strangles heat rejection — the most common slow-warm cause
Frosted evaporator (defrost failed)when the auto-defrost fails, ice builds until air can no longer pass — the freezer stays cold, the fridge warms
Evaporator or condenser fan stoppedone dead fan stops the cold from moving, and the symptom depends on which one
Door gasket leakinga torn gasket runs the compressor flat out and still loses the race, usually with visible frost at the seal
Compressor or its relaya warm compressor that never runs, or one that clicks and stops, points here — a relay is cheap, a compressor is not

Ranked for this refrigerator in general. Answer three questions inside a case and the list gets shorter.

Verdict, in general terms

A relay is $15–$40, a fan $40–$90, a defrost heater or sensor $20–$60 as parts — all worth fitting to a working fridge. A compressor replacement runs $650–$1,200 installed, which on a fridge over about 10 years old tips to replace. Sealed-system work is a stop line either way.

The checks, in order

4 checks

Check 1 — Clean the condenser coils
20 minutes · vacuum, a coil brush if you have one
This eliminates: dirty condenser coils.
The step-by-step opens inside a case.
Check 2 — Listen for both fans
5 minutes · no tools
This eliminates: stopped evaporator or condenser fan.
The step-by-step opens inside a case.
Check 3 — Check the freezer for frost buildup
10 minutes · no tools
This eliminates: failed defrost, frosted evaporator.
The step-by-step opens inside a case.
Check 4 — Watch and listen to the compressor
15 minutes · no tools
This eliminates: dead relay versus dead compressor.
The step-by-step opens inside a case.

Stop line

The refrigerant circuit — compressor internals, evaporator and condenser coils, the sealed tubing — is a licensed-technician job in most places, and no page improves on that. What you have already learned still shapes the visit.

What to tell the technician: "The fridge went warm. The coils are clean, both fans run, the freezer is frost-free, and the compressor relay clicks but the compressor never starts." — say what your checks actually showed.
What to ask: Ask them to test the compressor and its relay, and to quote a compressor replacement and a full replacement side by side before starting.
What a fair price looks like: A relay or sensor diagnosis typically lands at $90–$180 with the part. A compressor job runs $650–$1,200 installed. A comparable new fridge is $1,200–$2,500.
