Quick answer: A Frigidaire refrigerator that runs but doesn't cool is usually a defrost system failure (frost blocking airflow), failed evaporator fan, or condenser coil dust buildup. Most common quick win: clean condenser coils (free, 15 min). Most common parts fix: defrost timer 215846602 — $48, 30 min job.

Most likely culprit: Frost buildup blocking airflow (50%) OR dirty condenser coils (30%).
Time to fix: 15 min - 1 hour.
Difficulty: Easy to Medium.
If your Frigidaire refrigerator is warm, food spoils faster, or freezer barely freezes, three causes account for 90%: dirty condenser coils (30%), defrost system failure (50%), or evaporator fan motor failed (20%).
Cause 1 — Dirty condenser coils (30%)
Coils on bottom or back of fridge accumulate dust over years, blocking heat dissipation. Compressor runs constantly, never reaches temp.
Fix: Pull fridge out, vacuum coils with brush attachment. Free, 15 min. Do every 6 months.
Cause 2 — Defrost system failed (50%)
Frost on evaporator coils blocks airflow from freezer to fridge compartment. Fridge stays warm even though freezer cold.
How to confirm: Remove freezer back panel. Visible thick ice = defrost issue.
Fix: Manual defrost first (unplug 8-12 hours, doors open). Then replace defrost timer (OEM 215846602) and/or thermostat. Typical price $45-$60. Difficulty: Medium — 30-45 min.
Cause 3 — Evaporator fan motor failed (20%)
The fan circulates cold air from evaporator to fridge compartment. Failed = warm fridge, freezer slightly cold.
How to confirm: Open freezer door — should hear fan running. Silent = fan dead.
Fix: Replace evap fan motor ($30-$60). Difficulty: Medium — 45 min.

Frequently asked questions
Q: How often should I clean condenser coils?
A: Every 6 months. Pets in home → every 3 months (fur clogs faster).
Q: My freezer works but fridge is warm. Same issue?
A: Yes — defrost OR evaporator fan failure. See Causes 2-3.
Q: How long should I wait after manual defrost before deciding it didn't fix?
A: 24 hours. If frost returns within 1 week → real defrost component issue.
Q: Is fixing this worth it vs new fridge?
A: Yes if fridge < 10 years old. New fridge $1000-$3000 vs $50 part DIY.
Q: My fridge is humming louder than usual. Related?
A: Yes — overworked compressor due to dirty coils or restricted airflow. Address Cause 1 first.
