Why is my Frigidaire refrigerator not cooling?
On Frigidaire refrigerators, a warm fridge while the freezer stays cold is most often a defrost system failure with iced-over evaporator coils ($200 – $400 repaired) or a failed evaporator fan ($150 – $300). If both compartments are warming, the compressor start relay is the first thing to check ($100 – $200) — it's a $20 part and a common Frigidaire failure that masquerades as a full compressor failure.
Frigidaire's compressor start relay sits on the side of the compressor at the back of the unit and is notorious for failing before the compressor itself does. Shaking the relay — if you hear a rattle, it's dead. Replacing it costs under $20 in parts and can restore cooling the same day, making it the smart diagnostic step before approving a $500+ compressor quote.
Most likely causes
Defrost system failure (evaporator iced over)
$200 – $400How to tellFreezer is cold but fresh food section is 50–60°F or warmer; frost is visible behind the freezer back panel; the fan runs but airflow into the fridge is choked by ice buildup
The fixManual defrost test: unplug the unit for 24–48 hours with doors open. If cooling returns, the defrost heater, defrost thermostat, or defrost control timer needs replacement.
Evaporator fan motor failed
$150 – $300How to tellFreezer is at temp but fresh food section is warm; no fan sound from inside the freezer; manually pressing the door switch — the fan doesn't run
The fixReplace the evaporator fan motor behind the freezer back panel
Compressor start relay failed
$100 – $200 installedHow to tellBoth compartments warming over 24–48 hours; clicking sound every few minutes from the back of the unit (compressor trying to start and failing); compressor may be warm to the touch but not running
The fixPull the start relay off the compressor terminals, shake it — if it rattles, it's failed. Replace the relay ($15–$25 part) before any compressor work is approved.
Dirty condenser coils
$0 DIY / $75 – $150 as part of a service callHow to tellGradual cooling loss over months; unit runs constantly; coils at the bottom behind the base grille caked with dust, lint, and pet hair
The fixClean condenser coils — DIY with a vacuum and coil brush, or included in a service call. A severely dirty coil can cause 15–20°F temperature rise in the fridge section.
Compressor or sealed-system failure
$400 – $900+How to tellBoth compartments warm; relay was replaced but no improvement; compressor won't start or runs without cooling; refrigerant leak suspected (hissing or oily residue near coils)
The fixSealed-system repair or compressor replacement — requires EPA 608 certification. Apply the 50% rule before approving.
Try this first (before you pay anyone)
- Go to the back of the refrigerator, find the compressor (large black rounded unit at the bottom), and locate the small relay plugged into the side of it. Pull it off and shake it next to your ear. If it rattles, the relay is dead — order a replacement for $15–$25 and snap it on. This alone restores cooling on many Frigidaire no-cool calls.
- Open the freezer and hold down the door switch while the door is open. The evaporator fan should run. If you hear nothing, the fan motor is the problem — and it's a cheaper repair than anything involving the compressor.
- Vacuum or brush the condenser coils at the bottom behind the front base grille. Frigidaire bottom-freezer and French door models accumulate lint fast near the floor. Two minutes with a vacuum can restore noticeably better cooling.
- Unplug the refrigerator for 24–48 hours with the doors propped open to manually defrost. If it cools normally for several days after restart, the defrost system (heater, thermostat, or timer) is failing — not the compressor.
Unlock the hiring checklist
Use this before you call an appliance repair, so you know what to ask and what to avoid.
Call a pro when…
- The start relay doesn't rattle but both compartments are warm — the compressor itself may be failing and needs amp-draw testing to confirm
- The manual defrost trick worked but cooling failed again within a few days — the defrost heater or thermostat needs replacement to prevent recurrence
- You hear hissing from the back of the unit or see an oily residue near the coils — that's a refrigerant leak, which requires EPA 608-certified equipment to find and repair
- The fresh food section is warm but the freezer is fine — evaporator fan and defrost access require removing the freezer back panel
Repair or replace?
Frigidaire refrigerators run about 12–15 years. A start relay replacement at $100–$200 or a defrost system repair at $200–$400 on a Frigidaire under 10 years old is almost always worth doing. Past 12 years, apply the 50% rule: if the repair quote exceeds half the price of a comparable new unit ($900–$1,800 for a similar Frigidaire), put the money toward replacement. A compressor failure on a refrigerator over 10 years old is the classic case where the 50% rule tips toward replacement — especially if the unit has had prior defrost repairs.

Related questions
How do I check the start relay on a Frigidaire refrigerator?
Pull the refrigerator away from the wall. At the back, find the compressor — the large black rounded component at the bottom. On the side of the compressor is a small plastic relay plugged into the terminals. Pull it off (it clips on) and shake it next to your ear. If it rattles, the relay is dead. A new relay is $15–$25 on Amazon and plugs right on — it's the first thing to try before calling a tech for a no-cool Frigidaire.
Why is my Frigidaire fridge warm but the freezer is cold?
Warm fridge with a cold freezer on Frigidaire almost always means one of three things: the evaporator fan isn't moving cold air from the freezer into the fresh food section, the evaporator coils are iced over from a defrost system failure, or the damper between the two sections is stuck. None of these is a compressor problem.
How much does it cost to fix a Frigidaire refrigerator that won't cool?
A start relay replacement runs $100–$200 installed. A defrost system repair (heater + thermostat) runs $200–$400. An evaporator fan replacement runs $150–$300. A compressor repair runs $400–$900+. Diagnostic visits run $75–$150 and are typically credited toward repair. Cleaning condenser coils is free to do yourself.
Should I repair or replace my Frigidaire refrigerator?
For defrost, fan, or relay repairs under $400 on a unit under 10 years old, repair. For compressor work on a unit past 10 years, run the 50% rule: if the repair quote exceeds half the replacement cost of a comparable new unit, buy new. An honest tech will tell you which side of that line you're on.
