Kenmore Refrigerator Not Freezing in Memorial, TX
π Call (346) 512-3688π§ Performed by Serhii T.
The Problem
- β’Freezer compartment not getting cold, food thawing inside
- β’Refrigerator section sitting at room temperature while compressor runs constantly
- β’Loud humming noise from the back wall of the freezer
π Diagnosis
When I arrived at the home in Memorial, the customer described the same pattern I see often with Kenmore top-freezer and bottom-freezer units: the compressor was running non-stop, but neither the freezer nor the fresh food compartment was holding temperature. The freezer was sitting at 28Β°F instead of the target 0Β°F, and the refrigerator section read 52Β°F instead of 37Β°F. That spread told me immediately the sealed system itself was likely intact, and the problem was in airflow or the defrost circuit. I pulled the freezer back panel to expose the evaporator coil assembly. What I found was a solid block of frost covering the entire coil, which is a textbook sign that the defrost system had been failing for weeks. The evaporator fan motor was also seized. I confirmed this by spinning the fan blade by hand, it would not rotate freely. I tested the defrost heater with a multimeter and got an open circuit reading, 0.0 Ξ© where I expected roughly 25 to 30 Ξ©. The defrost thermostat tested within spec. The root cause was a combination of a failed defrost heater that allowed frost to accumulate unchecked, followed by the fan motor seizing under the load of trying to push air through a coil completely encased in ice.
π§ The Repair
- βStep 1: Disconnected the Kenmore unit from power and removed all contents from the freezer compartment to allow full access to the rear evaporator panel.
- βStep 2: Removed the freezer back panel by taking out the retaining screws along the perimeter and carefully releasing the wire harness clips attached to the panel.
- βStep 3: Documented the frost buildup covering the evaporator coil with a photo before proceeding, showing the severity of the blockage.
- βStep 4: Used a heat gun on the lowest setting to manually defrost the evaporator coil, clearing all ice from the coil fins and the fan housing area. Collected melt water with towels.
- βStep 5: Disconnected the defrost heater wiring connector and removed the heater element from the clips mounted along the bottom of the evaporator coil. Installed the replacement defrost heater rated for this Kenmore evaporator assembly.
- βStep 6: Removed the seized evaporator fan motor by releasing the mounting bracket screws and disconnecting the motor plug. Installed a direct-fit replacement motor and confirmed the fan blade spun freely by hand before reconnecting.
- βStep 7: Reassembled the rear evaporator panel, reconnected all wire harness clips, and restored power to the unit. Manually triggered a defrost cycle using the Kenmore service mode to verify the new heater element drew correct amperage.
- βStep 8: Checked temperatures after a 2-hour runtime. Freezer measured 1Β°F and fresh food compartment measured 36Β°F, both within the target operating range. Confirmed fan motor was circulating air properly with no unusual noise.
β Result
After the 2-hour runtime check, the freezer reached 1Β°F and the refrigerator section stabilized at 36Β°F. The compressor was cycling normally instead of running continuously. The customer confirmed no unusual noise from the freezer. Total repair time on site was approximately 2 hours including the manual defrost. A 90-day labor warranty was provided on both replaced components.
π‘ Technician Notes
Kenmore units built on LG platforms, which covers a large percentage of models sold under the Kenmore name, share a common weakness in their defrost heater design. The heater element sits in a position where water pooling during defrost cycles corrodes the element contacts over time. In Houston's humidity, this process moves faster than in dryer climates. If your Kenmore freezer starts running warmer than usual but the compressor sounds like it's working hard, do not wait. Within a few weeks, a minor frost buildup becomes a solid block that stresses the fan motor to the point of failure, turning a single-part repair into a two-part job. Check your freezer temperature with a simple thermometer monthly. If it reads above 10Β°F consistently, call for service before the coil freezes over completely.
Frequently Asked Questions
Why is my Kenmore freezer not freezing even though the compressor is running?
A running compressor with no freezing is almost always an airflow or defrost problem, not a sealed system failure. In Kenmore units, the most common cause is a frost-blocked evaporator coil caused by a failed defrost heater. The compressor works but the cold air cannot circulate because the coil is buried in ice and the fan motor seizes.
How much does it cost to fix a Kenmore refrigerator that stopped freezing in Houston?
For the combination of a defrost heater and evaporator fan motor replacement, the repair in the Houston area typically runs between 180 and 320 dollars depending on the specific Kenmore model and part availability. Catching the issue early, before the fan motor seizes, reduces the cost to roughly 120 to 180 dollars for the heater alone.
What happens if I ignore my Kenmore freezer not freezing and keep using it?
Ignoring the problem causes the frost buildup to grow thicker each day, putting increasing strain on the evaporator fan motor until it burns out. Food safety becomes a concern quickly once the freezer climbs above 20Β°F. Extended compressor run time also raises the risk of compressor overheating, which converts a 200-dollar repair into a 600-dollar or more sealed system job.
Is it worth repairing a Kenmore refrigerator that is not freezing, or should I replace it?
If the sealed system is intact and the failure is in the defrost circuit or fan motor, repair is worth it in most cases. Kenmore units built on Whirlpool platforms are reliable once the defrost system is restored. Replacement only makes financial sense if the compressor or sealed system has failed on a unit older than 12 years.
How do I manually defrost a Kenmore refrigerator to get it working temporarily while I wait for a technician?
Unplug the unit, remove all food, and leave both doors open for 24 to 48 hours with towels on the floor to catch melt water. This clears the frost from the coil and restores temporary cooling once you plug it back in. The defrost heater is still failed, so the coil will refreeze within one to three weeks. Manual defrosting buys time but is not a fix.
