Why Is My Kenmore Freezer Not Cold Enough?

Why Is My Kenmore Freezer Not Cold Enough?

Defrost system problems and dirty condenser coils fan failures, leaky door gaskets or control issues can lead to problems with your Kenmore freezer not getting cold enough. It’s possible that you don’t notice the issue immediately, but your refrigerator and freezer are likely to become too hot. It is essential to fix the problem immediately to avoid food loss.

How to prevent your Kenmore freezer freezing by preventing air leaks If your Kenmore freezer isn’t sufficiently warm to ensure that the frozen ice cream stays from becoming too firm or you notice a lot frost in the freezer the freezer, warm, humid air could be coming out of the refrigerator. Replace damaged gaskets and inspect the door gaskets. If the gaskets appear to be in good condition however the door is sliding over its hinges, or causing gaps between the door gaskets and cabinet, adjust the Kenmore refrigerator hinges to make sure that the gaskets are able to are able to seal the cabinet. If you see frost buildup just on the rear freezer wall, the automatic defrost system might be malfunctioning. If the defrost mechanism is functioning properly it melts the frost off the evaporator coils approximately every 8 hours to ensure that the air passages in the the evaporator clean and allow the refrigerator and freezer compartments to cool properly.

Frozen builds over the back of the freezer compartment wall and the evaporator if the automatic defrost mechanism fails. The buildup of frost blocks cooling air paths through the evaporator so the Kenmore freezer isn’t able to cool properly. How to fix other problems that prevent your freezer from getting cold enough If the evaporator fan isn’t running, check the freezer compartment to see if it is cooling. If it’s not working, replace the fan that is evaporating. Dirty condenser coils could cause cooling issues in the freezer. You should disconnect your Kenmore refrigerator to look for dirt and dust buildup. If they are dirty, clean the condenser tubes.

If your performing routine Kenmore refrigerator service Continue to clean the coils. If the freezer is not being cold enough, make sure that the condenser fan is running. The condenser won’t effectively cool refrigerant when the condenser fan does not operate. If the fan for the condenser isn’t turning on, replace it. These repairs can help resolve your refrigerator problems Replace the Kenmore refrigerator freezer sensor. The Kenmore refrigerator freezer sensor (also known as the defrost bimetal termination thermostat) trips when it detects that the temperature is enough to overheat. The defrost sensor will go off when it senses the heater has become too hot. If the defrost detector is triggered, it shuts off the power supply to the heater.

Over time, frozen ice can form on the evaporator’s fins and cause the freezer and fridge not cool down well. The volt/ohmmeter can be used to check the continuity of defrost sensors. If there isn’t any continuity around the temperature of 0°F, then it’s time to replace the defrost sensor. Clean the Kenmore condenser tubes of the refrigerator. The dusty Kenmore refrigerator coils could cause problems in the cooling system of your refrigerator as well as efficiency. Follow the instructions in the owner’s manual to cleaning condenser coils. Unplug the Kenmore refrigerator prior to accessing and cleaning the coils.

Most Kenmore refrigerators’ coils are located behind the bottom grill. Use a coil brush to cleanse the coils. Replace the Kenmore refrigerator’s condenser fans The fan is located inside the Kenmore refrigerator’s machine compartment, close to the compressor. The fan circulates air around the condenser coils to cool the refrigerant. The refrigerant is cooled before it moves through the expansion device before moving into the evaporator. Replace the condenser fan if it is damaged. Repair the Kenmore refrigerator defrost system: The Kenmore refrigerator’s automatic defrost feature regularly melts the frost in the evaporator to improve the exchange of heat. The compressor stops and the defrost heating elements are switched on.

During defrosting the frost melts from the evaporator fins. The condensate flows to an drip tray for the evaporator beneath the evaporator, and later is pumped through a drain tube and into the drain pan that is close to the compressor within the compartment of the machine. The condensate evaporates through the drain pan prior to the next defrost cycle. If the defrost procedure fails, identify and repair the problem. Replace the Kenmore refrigerator’s evaporator fan. The fan is connected to the evaporator. It circulates air through the cabinet to cool the appliance. It is possible to replace the evaporator fan if it’s damaged. Replace the Kenmore refrigerator’s temperature control board: The temperature control board-also called the electronic control board-is in the machine compartment close to the compressor behind a panel at the side of the Kenmore refrigerator. The temperature control board controls the compressor as well as other parts that make up the Kenmore refrigerator.

You can test it out by following the directions in the technical sheet. Change the temperature control board in case it does not work at all or isn’t controlling the components correctly. Change the Kenmore refrigerator thermostat temperature control thermostat. The thermostat is called the cold thermostat or cold thermostat and is located inside the housing for the control. The thermostat has an attached sensor tube it, which detects temperature within the Kenmore refrigerator cabinet. The temperature control thermostat controls the temperature inside the cabinet by turning it on and off the compressor based on the temperature sensed by the sensor tube. If it fails to sense temperature accurately or fails to cycle the compressor, the temperature control thermostat must be replaced. The Kenmore refrigerator thermostat needs to be changed. If the refrigerator isn’t cooling as it should the thermistor could be defective.

The thermistor transmits temperature data to the thermostat, so a broken thermistor will give bad information. Replace the Kenmore refrigerator’s defrost timingr. The defrost timingr is an electronic device that regulates the interval between defrost cycles. The motor that drives the defrost control elements and runs the control elements. The defrost motor stops when the control contacts of the device are in defrost mode. When the compressor is been shut down, the heater switches on for the specified time to melt the frost off of the evaporator fins. This facilitates a more efficient heat exchange between the evaporator as well as the compressor. The defrost timer contacts will turn back after the timer expires so that normal cooling can continue to the Kenmore refrigerator. If the heater for defrost ceases working, you will have to replace it. Faulty contacts in the timer could also cause the defrost heater to not be energized in any way or to constantly be energized. If this occurs, you should replace the defrost heater timer.


Adjust the refrigerator or freezer door:

Refrigerator or freezer doors swing on hinges that can be bent or damaged. Doors can shift over time. This can allow warm humid air to pass through the door of the freezer or refrigerator, which creates excessive frost, which could lead to the drain tube freezing. Repairing the refrigerator involves aligning and fixing the hinges to ensure that they work correctly. Replace the Kenmore refrigerator door gasket. The gasket may be damaged and permit warm, moist air to enter the Kenmore refrigerator door when it’s closed. This can cause excessive frost damage as well as cooling issues. If the seal has become damaged or worn, replace it. Replace the Kenmore refrigerator electronic control board: The electronic control board-also called the main control board or the power control board (PCB)-controls the compressor as well as the defrost cycle. The electronic control board sends current to the compressor and fans when it senses the refrigerator is in need of cooling down. To monitor temperatures inside the refrigerator or freezer, the electronic control panel receives signals via temperature sensors. The electronic control board then regulates the process of defrost by using this data.

To check the effectiveness of the electronic control board you can perform an examination for diagnostics. The test varies by model however the most commonly used is the Forced Defrost test. See the tech sheet for instructions on running the diagnostics. Replace the electronic control board if it’s not functioning correctly. Routine maintenance for Kenmore fridges Clean refrigerator coils cause problems with the freezer and refrigerator’s ability to properly cool and operate efficiently. Cleaning condenser tubes must be performed according to the instructions included in the owner’s manual.

Prior to taking care of the coils, disconnect your Kenmore refrigerator. In most refrigerators, the coils are behind the bottom front grill. Make use of a coil brush to clean the coils. Regular maintenance includes replacing the water filter, removing dust off the bottom of the grille as well as adjusting the hinges in case doors aren’t closing properly.
