Kenmore Refrigerator Not Cooling? Causes, Fixes and Costs
Keep food safe while you troubleshoot: the FDA says a refrigerator should stay at 40°F or below and a freezer at 0°F. Move milk, meat and leftovers to a cooler with ice if the fridge has been warm for a while (see food safety).
First: find out who made your Kenmore
Kenmore is a Sears brand, and its refrigerators were built by other manufacturers. The first three digits of the model number (on a label inside the fresh-food section) tell you which one, and that tells you whose instructions to follow for settings, demo mode and diagnostics.
- 106.xxxxx: Sears PartsDirect says “The ‘106’ prefix in the model number is the manufacturer code that identifies Whirlpool as the producer.” Whirlpool’s own troubleshooting steps apply.
- 253.xxxxx: Sears PartsDirect describes these as “typically associated with Frigidaire/Electrolux-style designs, not Whirlpool.”
- Any other prefix (Kenmore Elite and Pro included): look up the full model number on Sears PartsDirect, which lists the parts and manuals for that exact model, or check your owner’s manual.
The checks below work on every Kenmore refrigerator, whoever built it.
Kenmore refrigerator not cooling: match what you see
| What you notice | Most likely cause | Next step |
|---|---|---|
| Fridge warm, freezer still cold | Blocked vents, frost on the evaporator or a failed evaporator fan | Check vents, then frost and fans |
| Both fridge and freezer warm, lights on | Dirty or boxed-in condenser coils, condenser fan, or compressor | Coils and clearance, then compressor |
| New fridge or after a power cut: lights and display work but no cooling | Demo (showroom) mode or a control that needs a reset | Demo mode, reset |
| Fridge “not cold enough” after a temperature change | Hasn’t had time to settle | Wait 24 hours (settings) |
| Thick frost on the freezer’s back wall | Defrost system fault | Technician |
| Door doesn’t seal; condensation around the frame | Worn or dirty door gasket | Paper test |
| Clicking every few minutes, compressor never stays on | Start relay or compressor problem | Technician |
1. Check the settings, then wait 24 hours
Someone may have turned the control down, or a child may have pressed a button. Whirlpool, which built many Kenmores, recommends keeping a refrigerator “between 33°F and 40°F, with the ideal temperature right around 37°F.” The FDA adds that “few refrigerator controls show actual temperatures,” so put an appliance thermometer in a glass of water on the middle shelf to see the real number.
After any change, be patient. A Kenmore use and care guide says: “Always allow 24 hours for your refrigerator to reach a new temperature setting.” Changing the setting again every few hours makes things worse, not better.
2. Make sure it isn’t in demo (showroom) mode
Store display models are often left in demo mode, which keeps the lights and display working but switches the cooling off. Whirlpool’s help page describes the symptom: “The refrigerator and freezer will not cool, even after changing the temperature settings.” The button combination to exit demo mode differs by model, so look for “Demo” or “Showroom” in your owner’s manual (for a 106 model, Whirlpool’s demo-mode page for your refrigerator style).
3. Clear the air vents (fridge warm, freezer cold)
In a typical frost-free refrigerator, Whirlpool explains, “cold air is generated in the freezer and pushed into the fresh food section through vents.” If a bag of frozen vegetables or a pizza box covers the vent in the freezer, or food is pushed against the vent in the fridge, cold air can’t get through. Move food away from the vents in both sections and leave space for air to circulate. If the vents are clear and the fridge is still warm while the freezer is cold, see refrigerator not cooling but freezer works.
4. Test the door seals
A gasket that doesn’t seal lets warm, humid air in all day. Whirlpool’s test: “closing a piece of paper in the freezer door, then tug at the paper.” Do the same on the fridge door at several points around the frame. If the paper slides out easily, clean the gasket with warm soapy water and check the door isn’t blocked by a shelf or drawer. A torn or flattened gasket needs replacing.
5. Give the coils room to breathe
The condenser coils release the heat removed from inside the fridge. If they’re coated in dust or the fridge is boxed in, it can’t shed heat and cools poorly.
- Clearance: Whirlpool recommends “½ inch clearances on the sides and 1 inch in the back.” A fridge pushed tight into a cabinet run can struggle.
- Room temperature: For its top-freezer models, Whirlpool lists an operating room range of 55°F to 110°F. A fridge in a cold garage or a very hot one may not cool properly.
- Cleaning: Whirlpool notes that “there is typically no need for routine condenser cleaning in a normal home operating environment,” but recommends cleaning “every 2 to 3 months” in dusty homes or homes with pets. Unplug the refrigerator first (the Kenmore guide says “Unplug refrigerator before doing anything with electrical system”), then vacuum the coils behind the bottom grille or at the back, depending on the model. Some models’ coils can only be reached by a technician.
⚠️ Caution: unplug before you open anything
Unplug the refrigerator before you remove a grille or panel, clean the coils or touch any part, and keep food in a cooler meanwhile. Never test fans, relays or wiring with the power on, and never bypass a safety device. Anything involving refrigerant, the compressor or a sealed-system leak needs an EPA-certified technician. If you aren’t comfortable doing this, call a qualified appliance technician.
6. Reset the refrigerator
A control glitch after a power cut or surge can stop cooling. Sears Home Services suggests unplugging the refrigerator (or switching off its breaker) for 2 minutes and then restoring power. Set the controls to the recommended setting and allow the full 24 hours before judging the result. There is no homeowner “compressor reset” button on a Kenmore; if a power cycle doesn’t bring the compressor back, it needs a technician.
7. Frost on the freezer wall or a silent fan
Frost-free refrigerators run a defrost heater a few times a day to melt frost off the evaporator coil behind the freezer’s back panel. If the heater, its thermostat or the control fails, frost builds up until it blocks the airflow to the fridge. A thick, even layer of frost on the freezer’s back wall is the clue. The evaporator fan, which pushes cold air through the vents, can fail the same way: if you can’t hear it with the freezer door closed and the compressor running, it may have stopped.
Whirlpool’s guidance is that work on the evaporator fan, condenser fan, compressor or start relay “should be left to a professional.”
8. Compressor and sealed system
If both sections are warm, the coils are clean and the condenser fan runs, but the compressor (the black tank at the back, bottom) is silent, clicks on and off every few minutes, or runs constantly without cooling, the problem is the start relay, the compressor or a refrigerant leak. Refrigerant work requires EPA Section 608 certification, so this is always a technician job. Get a quote before deciding: on an older fridge, a compressor repair can cost close to a new refrigerator (see costs).
Food safety while it’s warm
- FoodSafety.gov: a refrigerator “will keep food safe for up to 4 hours during a power outage if you don’t open the door,” and a freezer for “up to 48 hours in a full freezer and 24 hours in a half-full freezer.”
- The FDA says to discard perishable food such as meat, milk and leftovers that has been above 40°F for two hours or more.
- Frozen food that “still contains ice crystals or is 40°F or below” is safe to refreeze or cook (FDA).

When to call a technician
Call for service if the fridge still isn’t at 40°F or below 24 hours after the checks above, if frost keeps coming back on the freezer wall, if the evaporator fan is silent, or if the compressor clicks, hums without starting or never shuts off. Have the full model number (with its three-digit prefix), your thermometer readings and what you’ve tried. Print the checklist.
Frequently asked questions
Why is my Kenmore refrigerator not cooling but the freezer is cold?
Cold air reaches the fridge through vents from the freezer. Blocked vents, frost on the evaporator coil from a defrost fault, or a failed evaporator fan stop that air. Clear the vents first; frost on the freezer’s back wall or a silent fan needs a technician.
How do I reset my Kenmore refrigerator?
Unplug it or switch off its breaker for 2 minutes, then restore power, set the recommended temperature and allow 24 hours for it to settle.
How do I reset the compressor on a Kenmore refrigerator?
There’s no homeowner compressor reset. A power cycle resets the controls; if the compressor still doesn’t run, a technician needs to check the start relay, compressor and refrigerant.
Why is my Kenmore Elite refrigerator not cooling?
The same causes apply: settings, demo mode, blocked vents, door seals, coils, then the defrost system, fans or compressor. Check the model number prefix to find which manufacturer’s manual and steps apply to your Elite.
What temperature should a Kenmore refrigerator be?
40°F or below for the fridge (FDA), with around 37°F ideal (Whirlpool), and 0°F for the freezer.
How long does it take a refrigerator to get cold again?
Allow 24 hours after a reset or setting change before deciding whether it’s working.
