You open the refrigerator door, reach for something cold — and feel warm air. The shelves are at room temperature, the drinks aren’t chilled, and that familiar hum suddenly sounds suspicious. If your Kenmore fridge is warm, you’re not imagining things, and you’re definitely not alone.
A Kenmore refrigerator not cooling is one of the most common calls we take across metro Atlanta. It’s not always a catastrophic failure — sometimes the fix is straightforward. Sometimes it points to a deeper mechanical issue that won’t resolve on its own. Either way, a fridge warm enough to spoil food needs attention today, not next week.
The causes range widely. On one end: dirty condenser coils, a blocked vent, a bumped control — things you can check yourself. On the other end: a failing compressor or a refrigerant leak — work that needs professional diagnosis and the right equipment.
Kenmore is a Sears brand, and its refrigerators differ a lot from model to model, so settings and coil access depend on yours. Where Kenmore spells something out, we quote its use and care guides — yours comes first.
This guide walks you through the most likely culprits, explains what’s actually happening inside the appliance, and helps you decide whether this is a DIY situation or time to call a technician. We serve Atlanta and the surrounding Georgia areas with same- or next-day service on most days — because when the fridge stops working, waiting isn’t really an option.
Why Is Your Kenmore Refrigerator Not Cold? Common Causes Explained
When a Kenmore refrigerator stops cooling properly, the root cause usually falls into one of a few well-known categories. In our experience, these three come up most often.
Dirty Condenser Coils
The condenser coils release heat from the refrigerant into the room. Think of them as the exhaust system of your refrigerator — if they’re clogged, heat can’t escape, and the whole cooling cycle suffers.
On some Kenmore models the coils sit behind the base grille at the bottom; on others they’re on the back of the cabinet. Over time, dust, pet hair, and debris build up on them. When that layer gets thick enough, the refrigerator has to work harder to hold temperature — and eventually, it can’t keep up. Kenmore’s troubleshooting tables put it plainly: dirty coils prevent air transfer and make the motor work harder.
This is more common in homes with pets. One Kenmore top-mount guide says coils may need cleaning as often as every other month; a side-by-side guide says every 3 months.
Where the fridge sits matters too. Kenmore rates many of its refrigerators for a room between 55°F and 110°F (13–43°C) and warns that outside that range cooling can suffer. A garage fridge in a Georgia July can drift out of that range without anything being broken.
Condenser Fan Motor Failure
The condenser fan pulls air across the coils to carry heat away. If the Kenmore condenser fan motor is not working, the compressor runs hot and the refrigerator loses its ability to cool — even though the unit appears to be running normally.
A telltale sign: the fridge is humming, the interior light works, but the temperature keeps climbing, and the soft whoosh of air at the base is gone. Don’t test the blade with your fingers on a running fridge — with the power off, a technician checks whether it turns freely and whether the motor gets voltage. This is a part replacement job — not a repair.
Faulty Start Relay
On many compressors, a small start relay sits on the side of the compressor and gives it the electrical kick it needs to start each cooling cycle. When it fails, the compressor either won’t start at all or tries to start and immediately shuts off.
The classic test — pull the relay and shake it; a rattle means it’s burned out — is a technician’s check, not a homeowner’s. The relay plugs onto live compressor terminals behind the lower rear cover, and one Kenmore Elite guide tells owners not to remove the panel covering the condenser area at all.
Know which clicks matter. Kenmore says the defrost control and the thermostat click when they cycle — that’s normal. What isn’t: a click, a short hum, then silence, repeating every few minutes — and a refrigerator that’s getting warmer by the hour.
Defrost System Failures and Ice Buildup in Kenmore Fridges
Here’s a scenario that surprises a lot of people: the freezer looks fine, maybe even has frost on the walls — but the refrigerator section is warm. That’s often a defrost system problem, not a compressor problem.
How the Defrost Cycle Works
Frost-free Kenmore refrigerators “regularly run an automatic defrost cycle” to keep ice off the evaporator coils. The system has three main components:
- Defrost timer or control board — starts the cycle
- Defrost heater — melts accumulated frost off the evaporator
- Defrost thermostat (bi-metal) — cuts off the heater once a safe temperature is reached
Cooling pauses during a normal defrost — Kenmore’s guides say to wait about 30 minutes for it to end. If any one of these parts fails, frost accumulates unchecked — and that’s where the real trouble starts.
Evaporator Coils Iced Over — What It Means
The evaporator coils sit behind a panel in the freezer compartment. Their job is to absorb heat from inside the refrigerator. When the defrost system fails, ice builds up on these coils until they’re completely encased — and airflow stops.
The fan behind them is still running, but it’s essentially blowing air into a wall of ice. Cold air can’t reach the fresh food section, so the fridge feels warm even though the freezer appears to be working.
Signs: heavy frost or a solid sheet of ice on the back wall inside the freezer, a faint humming sound, and a refrigerator section that’s noticeably warmer than it should be.
A thermistor problem can contribute too. The thermistor is a temperature sensor that reports to the control board; if it reads wrong, the board may start defrost at the wrong time — or not at all.
When to Call a Professional
A manual defrost — fridge unplugged and emptied, doors open, towels down, until all the ice has melted — will temporarily bring cooling back. But it doesn’t fix anything. Within days or weeks, the ice returns, because the failed part is still there.
Diagnosing a defrost failure properly takes a multimeter and the wiring diagram for your exact model. Testing the heater, thermostat, and thermistor individually takes time and the right approach. Guessing and replacing parts one by one gets expensive fast — we’d rather you buy one part, not three.

The LG Linear Compressor Lawsuits: What Kenmore Owners Need to Know
This section matters if your Kenmore was built with an LG linear compressor and has stopped cooling. Not every Kenmore has one — your model number tells you what you own.
Why Some Kenmore Fridges Use LG Compressors
Kenmore is a Sears brand — its guides are published by Sears — and not every Kenmore is built the same way. Some Kenmore refrigerators were made with LG’s linear compressor, which LG literature describes as using less energy and making less noise than other compressors.
On paper, it was a compelling design. In practice, enough owners reported early failures that the issue ended up in federal court.
What the Lawsuits Claim
In January 2024, NBC Los Angeles reported on a federal lawsuit filed for owners of LG and some Kenmore refrigerators with linear compressors. The suit asks to proceed as a class action, claims the compressor’s real lifespan is “nowhere near 10 years, let alone 20,” and seeks refunds for owners who bought one after 2018. LG told NBC it does not comment on pending litigation and is fighting the suit.
LG earlier settled a different class action covering select models bought between January 1, 2014 and December 31, 2017; the settlement states LG “specifically denies any alleged defect.”
What a worn-out compressor does is simple: it stops pumping refrigerant properly, and the refrigerator can’t cool — no matter what else is working. A refrigerant leak from the sealed system ends the same way.
Signs Your Compressor Is Failing
The symptoms don’t always appear all at once. Watch for:
- The refrigerator cools inconsistently — fine one day, warm the next
- The compressor starts, runs for a few seconds, then shuts off
- Clicking or buzzing from the lower back of the unit that repeats without the compressor staying on
- The back of the refrigerator feels unusually hot to the touch
- The freezer holds some cold, but the fresh food section is noticeably warmer
If you’re seeing two or more of these together, the compressor is the likely culprit.
Refrigerant Leak Repair Requires EPA Section 608 Certification
Refrigerant work isn’t something to do casually. Under Section 608 of the Clean Air Act, refrigerant handling is regulated at the federal level, and technicians who service equipment that could release refrigerant must hold EPA Section 608 certification. Any repair that opens the sealed system belongs with an EPA 608 certified technician who has the recovery equipment to do it safely.
Step-by-Step: What to Check Before Calling for Repair
Kenmore’s own advice is to try its troubleshooting steps first “to avoid the cost of an unnecessary service call” — and in our experience, a surprising number of not-cooling calls do have a simple explanation.
Before any check: unplug the refrigerator before you touch the base grille or the coils, and don’t take off covers over the compressor area. Pulling a loaded fridge from the wall is a two-person job.
Work through these in order:
- Check the power and the controls. Plugged in? Breaker tripped? Control set to OFF? Settings vary by model: one Kenmore side-by-side guide aims for 38–40°F (3–4°C) in the fresh food section and 0–2°F (about −18°C) in the freezer; one Kenmore Elite guide offers 33–46°F and −6°F to 8°F, with 24 hours between changes. A newly plugged-in fridge can take up to 24 hours to cool completely. On that Elite, a store Demo Mode disables all cooling and shows OFF on the panel — check your guide if the display looks unusual.
- Look for blocked vents inside the cabinet. Cold air moves from the freezer to the fresh food section through vents in the wall between them. If a bag of frozen vegetables is pressed against a vent, Kenmore warns the fridge can run too warm or build up moisture.
- Inspect the door gasket. Run your hand along the seal with the door closed. If you feel air escaping, or the gasket is cracked or pulling away from the frame, warm air is getting in constantly — and the refrigerator can’t compensate. Sticking gaskets: clean them, then add a thin coat of appliance polish or kitchen wax, Kenmore says.
- Check the condenser coils. With the fridge unplugged, remove the base grille or roll the unit out, and vacuum the coils if they’re coated in dust or pet hair; leave about 1 inch (2.5 cm) behind the cabinet when you push it back. On models like that Elite, vacuum only the condenser cover and vents.
- Listen to the compressor. A steady low hum — even a pulsating or high-pitched one — is normal, and at around 70°F Kenmore expects the compressor to run 40 to 80 percent of the time. Silence while the fridge warms, or a click-hum-click that never settles into a steady run, suggests a compressor issue.
- Check the freezer’s back wall. A thin layer of frost is normal. A thick sheet of ice — or a completely frozen-over surface — points to a defrost system failure.
If you’ve gone through all six steps and the refrigerator is still not cold, the problem is internal and needs proper diagnostic equipment to find.

Conclusion
A Kenmore refrigerator that won’t hold temperature is rarely a mystery — it’s almost always one of a handful of known failure points. Dirty condenser coils, a failed fan motor, a defective start relay, a broken defrost part, or a compressor at the end of its service life. Each has its own signature, and each needs a different approach.
The key is not to wait. A cooling problem that starts small can escalate quickly — spoiled food, a compressor running under stress, or a refrigerant leak that makes the repair more complex. Early diagnosis almost always means a simpler, less costly fix.
If the basic checks didn’t point to an obvious cause, or you’ve found the likely issue but aren’t comfortable tackling it yourself, that’s the right moment to call a professional. Our team works across Atlanta and the surrounding Georgia areas, and we know how to get to the root of this problem efficiently.
FAQ
1. How long does a typical Kenmore cooling repair take?
Many repairs are finished in a single visit. A faulty start relay, a failed condenser fan motor, or dirty coils can often be handled on the first visit. Defrost system repairs may need a follow-up if the exact part for your model has to be ordered.
2. Can cleaning condenser coils prevent my fridge from losing cooling?
Yes, and it’s one of the most underrated maintenance tasks. Clogged coils force the compressor to work harder and run hotter — Kenmore lists dirty coils as a cause of both long running and warm food. Follow your guide’s schedule (every other month to every 3 months in the guides above), and unplug first.
3. Is it worth repairing an older Kenmore refrigerator, or should I replace it?
It depends on the failure and the condition of the unit. A defrost or fan motor repair on a fridge that’s otherwise in good shape is usually worth doing. A compressor on a unit near the end of its life is a harder call — the repair can approach the value of the appliance. Check your warranty first: one Kenmore side-by-side guide covers the sealed system for five years and compressor parts for ten.
4. What should I do with my food if the refrigerator stops cooling suddenly?
Keep the doors closed — the FDA says an unopened refrigerator keeps food cold for about 4 hours — and move perishables to a cooler with ice. The FDA advises discarding refrigerated perishable food that has been above 40°F for 4 hours or more; frozen food that still has ice crystals or is at 40°F or below can be refrozen or cooked. When in doubt, throw it out.
5. How often should the defrost system be inspected on a Kenmore fridge?
There’s no fixed schedule — defrost parts run automatically. But if frost builds on the freezer’s back wall more than usual, or the refrigerator section starts running warmer, those are early signs worth checking before a full failure.
6. How soon can someone come out to fix my Kenmore refrigerator in Atlanta?
Usually same- or next-day across the Atlanta metro. When you call, give us the model number from the label and what you’re seeing, so we bring the right parts.
