Why is my refrigerator not cooling?
A refrigerator that's warm in the fridge section but still cold in the freezer is almost always an evaporator fan or defrost system failure ($150 – $300 repaired) — not a compressor problem. If both compartments are warming, that points to a more serious sealed-system issue ($400 – $900+), where the 50% rule matters most.
Most refrigerator no-cool complaints are caused by something blocking airflow from the freezer into the fridge section — either a frozen evaporator coil that can't defrost itself, or a fan motor that's stopped running. Both are fixable repairs that cost far less than a new fridge.
Most likely causes
| Cause | How to tell | The fix | Typical cost |
|---|---|---|---|
| Evaporator fan motor failed | Fridge is warm but freezer is still cold; you don't hear the fan running when you open the freezer; the fridge section may have some cooling near the top | Replace the evaporator fan motor — a straightforward repair behind the freezer back panel | $150 – $300 |
| Defrost system failure (frozen evap coils) | Fridge gradually warms over days; ice or frost buildup visible on freezer back wall; a manual defrost temporarily fixes it | Replace the defrost heater, thermostat, or control board — whichever component in the defrost circuit failed | $150 – $350 |
| Dirty condenser coils | Both compartments run warmer than set temp; compressor runs constantly; fridge is older and coils have never been cleaned | Vacuum the condenser coils — DIY with a coil brush, or included in a service visit | $0 – $100 |
| Door gasket failing or door left ajar | Fridge struggles to reach set temp; condensation or frost around the door; gasket visibly cracked or not sealing | Replace the door gasket or check door alignment — gasket replacement is a DIY repair | $50 – $150 |
| Compressor or sealed-system failure | Both fridge and freezer warming over time; compressor runs but gets unusually hot; clicking noise from the back | Sealed-system repair or compressor replacement — requires EPA-certified refrigerant handling | $400 – $900+ |
Try this first (before you pay anyone)
- Check the temperature settings — it sounds obvious, but a nudged dial (especially on dial-type models) is a common culprit after someone reaches into the back of the fridge.
- Listen for the evaporator fan when you open the freezer door and press the door switch. If the fan isn't running, that's your answer.
- Look at the back wall of your freezer compartment. A thick layer of frost or ice over the vents means the defrost system has failed and the coils are frozen solid — airflow to the fridge section is blocked.
- Pull the fridge out and vacuum the condenser coils at the back or underneath (depending on the model). Heavy dust buildup forces the compressor to work harder and raises temperatures throughout.
Call a pro when…
- The evaporator fan isn't running or defrost components need replacing — accessing these requires removing freezer panels and the work is easiest for a tech
- Both compartments are warming and the compressor is hot or clicking — sealed-system work requires EPA certification
- You have medication or a large supply of food at risk — a failing fridge is an emergency; call same-day
- The fridge is icing up faster than normal after a recent repair — a misdiagnosis may have left the root defrost cause untreated
Repair or replace?
Refrigerators typically last 12–15 years. An evaporator fan or defrost repair on a fridge under 10 years old is almost always worth it — you're spending $150–$350 on an appliance worth $800–$2,000 new. If the problem is a compressor or sealed-system failure, apply the 50% rule: if the repair quote exceeds half the price of a comparable replacement and the fridge is past 8–10 years old, replacement is usually the smarter call. An honest tech will give you both numbers.

Why is my fridge warm but my freezer still cold?
Cold air in your refrigerator comes from the freezer — it's pushed through a vent by the evaporator fan. If that fan fails or the evaporator coils ice over from a defrost failure, the freezer stays cold (the cold is already there) but the fridge section stops getting fresh cold air. This is one of the most common refrigerator repairs and it's far less expensive than a compressor.
How much does refrigerator repair cost?
Most refrigerator repairs fall in the $150–$600 range. An evaporator fan or defrost issue typically runs $150–$350 including parts and labor. A compressor or sealed-system failure can reach $400–$900+. The diagnostic visit ($75–$150) is usually credited toward the repair.
Should I repair or replace my refrigerator?
If the repair is under half the cost of a comparable new fridge AND the appliance is under 10 years old, repair it. If the repair is a compressor or sealed-system job on an older fridge, get a quote first — at $400–$900+, replacement often makes more financial sense, especially when the fridge has already hit its second decade.
How long does refrigerator repair take?
Most repairs — evaporator fan, defrost heater, thermostat — are completed in a single visit of 1–2 hours once the part is in hand. If the tech has to order a part, expect 2–5 business days. Compressor work is more complex and may require multiple visits.
