Frigidaire Refrigerator — Not Cooling / Warm Fridge

About the Issue

When a Frigidaire refrigerator stops cooling — whether the entire unit feels warm or temperatures slowly climb over several days — the cause is usually a failure in airflow, the sealed system, or temperature control. On Frigidaire Gallery and Professional series, adaptive defrost and multi-zone cooling make the system sensitive to airflow restrictions, fan issues, and thermistor drift.

A warm refrigerator can lead to food spoilage, excessive compressor run time, and damage to sensors or electronics if not diagnosed promptly. Our technician performs a full cooling-system evaluation during the $${PRICE} diagnostic (credited toward repair if approved).

Symptoms (What You May Notice)

• Fridge interior stays above 40–50°F even on coldest settings.
• Freezer may still be cold, or both sections may feel warm.
• Evaporator fan is noisy, slow, or silent.
• Back panel of the freezer shows heavy frost or ice sheet.
• Compressor runs continuously, or cycles rapidly.
• Warm spots, humidity, or condensation inside the fridge section.

Causes (Frigidaire-Specific Patterns)

• Defrost failure: iced-over evaporator blocks airflow to the refrigerator (bad heater, defrost thermostat, or adaptive board).
• Evaporator fan issue: seized motor, worn bearings, cracked shroud, or ice-blocked fan blade.
• Faulty thermistor: inaccurate temperature signals cause improper compressor/fan operation.
• Control board fault: no call for defrost, fan, or compressor output.
• Low refrigerant / sealed system issue: weak cooling, long run times, warm refrigerator even with cold freezer area.
• Blocked air channels: ice, debris, or food items obstruct cold-air flow between compartments.

Tests (How We Pinpoint the Fault)

We follow Frigidaire’s service diagnostics to isolate airflow, defrost, sensor, or sealed-system failure before replacing any part.

• Check actual temperatures and verify airflow volume from diffuser vents.
• Remove freezer panel and inspect frost pattern for defrost/sealed-system indications.
• Test evaporator fan voltage, speed, and shroud condition.
• Measure thermistor resistance vs. actual temps to detect drift.
• Verify control board outputs to compressor, fan, and defrost heater.
• Inspect for ice blockages in air ducts and return vents.

Repairs (What We Do to Fix It)

• Defrost the evaporator and repair faulty heater, bi-metal/thermostat, or adaptive defrost control.
• Replace weak/failed evaporator fan motors and damaged fan housings.
• Correct blocked airflow paths and clear return vents.
• Replace malfunctioning thermistors or control boards.
• Diagnose and repair sealed-system issues (low refrigerant, restriction, weak compressor).
• Verify proper temperature balance and restore stable cooling cycle.

After repairs, we run a full cooling performance test to confirm proper air movement, correct frost pattern, and stable temperatures (34–40°F fridge, 0–5°F freezer).

Prevention (Keep Temperatures Stable)

• Keep vents clear — avoid tall containers blocking airflow.
• Do not overload shelves; maintain space between items.
• Replace water & air filters on schedule to maintain circulation.
• Clean condenser coils every 6–12 months.
• Ensure doors close firmly and gaskets stay flexible.

If temperatures do not drop below 42°F within several hours after loading groceries, schedule a professional diagnostic.
