If your Frigidaire fridge is experiencing issues, you're not alone. Our detailed diagnostic guide covers exactly how to tackle the problem. Rated as a Professional repair, this procedure typically requires 20–45 min. By following the steps outlined below, you can safely identify the root cause—whether it's a worn component or a faulty sensor—and get your appliance running smoothly again.
Difficulty: Professional • Est. Cost: $150–$400+ for compressor or relay — sealed system requires EPA certification • Time: 20–45 min
Safety Warning: Prioritize safety: always unplug your fridge from the wall outlet and shut off related water or gas valves before removing access panels.
1. Quick Checks Before Diagnosis
Verify the temperature control dial inside the fridge hasn't been accidentally turned to the lowest/off setting. Set it to position 4 or 5 (mid-range).
- Feel the condenser coils at the back or underneath the fridge — if they're cold or room temperature instead of warm/hot, the compressor is not running or the sealed system has lost refrigerant.
- Listen carefully near the bottom rear of the fridge. You should hear a low, steady hum from the compressor. A clicking sound every few minutes followed by silence means the compressor is trying to start but failing.
2. Testing the Compressor Start Relay
Unplug the refrigerator. Pull it away from the wall and remove the lower rear access panel.
- Locate the compressor — the black, football-shaped unit with copper tubes. On its side is a small plastic box: the start relay and overload protector.
- Unplug the start relay by pulling it straight off the compressor pins. Shake it gently — if you hear a rattling sound like a broken maraca, the relay is burned out and must be replaced.
- You can also test with a multimeter between the start and run pins: a good relay reads 3-12 ohms. OL means it's open and dead.
3. Checking the Condenser Fan Motor
The condenser fan is located next to the compressor behind the rear access panel. It must run whenever the compressor runs to cool the condenser coils.
- Try spinning the fan blade by hand. It should spin freely. If it's stiff, the motor bearings are seized.
- If the fan doesn't run when the compressor kicks on, test the motor windings: disconnect the wires and measure resistance across the motor terminals. A healthy fan motor reads 20-60 ohms.
- A dead condenser fan causes the compressor to overheat and trigger the overload protector, resulting in the clicking-then-silence pattern.
4. Compressor Winding Test
With the start relay removed, you can access the 3 compressor pins directly: Common (C), Start (S), and Run (R).
- Test resistance: C-to-S should read approximately 10-20 ohms. C-to-R should read approximately 5-10 ohms. S-to-R should equal the sum of the other two readings.
- If any reading shows OL (open) or 0 ohms (shorted), the compressor motor winding has failed. This is a sealed system repair requiring a licensed refrigeration technician.
- Also test from each pin to the compressor body (ground). Any continuity to ground means the motor is shorted to the case — the compressor must be replaced.
5. When to Call a Professional
If the start relay and condenser fan are both good but the compressor still won't run, the compressor itself has likely failed. Compressor replacement requires EPA-certified refrigerant recovery equipment.
- If the compressor runs but the fridge isn't cooling, the sealed system may have a refrigerant leak. Look for oily residue on copper tubes — this indicates a pinhole leak where refrigerant oil has seeped out.
- Sealed system repairs (compressor, refrigerant recharge, evaporator/condenser replacement) typically cost $400-$800 in labor and parts. For a basic top-freezer model, compare this against the cost of a new unit.
- Frigidaire offers a 5-year limited sealed system warranty on many models. Check your purchase date and model number at frigidaire.com before paying for compressor repair out of pocket.
