Why Is My KitchenAid Freezer Not Cold Enough?

Your KitchenAid freezer might not be cold enough due to problems like a defroster system problem or dirty condenser coils, fan malfunctions or leaky gaskets for the doors. You may not see the problem right away, but the refrigerator and freezer are likely to become too hot. You will need to correct the problem immediately to avoid food loss. How to prevent air leaks that keep your KitchenAid freezer from getting cold enough If your KitchenAid freezer is not warm enough to ensure that the frozen ice cream stays from becoming too firm, or you notice lots of frost inside the freezer, warm, humid air could be coming out of the refrigerator.

Repair any damaged door gaskets by examining all doors for damage. If the gaskets are in good condition however a door is sagging on its hinges and creates gaps between the door gasket and the cabinet that surrounds openings in the doors, you can adjust the hinges on the KitchenAid refrigerator doors to ensure that the gaskets are sealed to the cabinet around the door openings. If frost is only visible on the back freezer wall, the automatic defrost may be failing. The defrost system is effective and melts the frost off the coils in the evaporator each 8 hours to ensure clear air passages through the evaporator so that the freezer and refrigerator compartments can cool down properly. The defrost mechanism that is automatic can fail, and the frost can build up on the evaporator or back freezer compartment walls.

The KitchenAid freezer isn’t cooling properly because of the accumulation of frost on the evaporator. How to fix other issues that prevent your freezer from getting enough cold If you notice that the fan in the evaporator isn’t running when you check for cooling inside the freezer compartment. If it isn’t working properly, change the fan. If the condenser coils are not clean, it can cause cooling issues. You should unplug your KitchenAid refrigerator to look for dirt and dust buildup. If the coils are stained, clean the coils. When you are conducting routine KitchenAid refrigerator maintenance Continue to clean the coils. You should check whether the condenser fan is turned off when your freezer does not become cold enough. If the fan ceases to run and the condenser stops working, it will not cool refrigerant efficiently. Replace the condenser fan if it isn’t running when it is activated.

There Repairs May Help Solve Refrigerator Problem

Replace the KitchenAid refrigerator sensor. The KitchenAid refrigerator sensor, sometimes known as the defrost bi-metal termination thermostat, trips when it senses that the temperature of the evaporator is at a high enough level that it is at risk of overheating. When the defrost sensor is activated, it turns off power to the heater for defrost. If the defrost sensors trips due to a problem with its operation, then frost can buildup on the evaporator fins. This eventually causes the refrigerator and freezer to fail to cool properly. The volt/ohmmeter is a tool to check the continuity of defrost sensors.

Replace the defrost sensor if it shows no continuity around 0° F. Clean the KitchenAid refrigerator’s compressor coils. Dust-covered KitchenAid refrigerator compressor coils can hinder the refrigerator and freezer from operating efficiently and cooling properly. Cleaning condenser tubes should be done according to the directions in the owner’s manual. Before you can get access to and clean the coils inside your KitchenAid refrigerator, disconnect it. The coils can be found in the back of most KitchenAid refrigerators. Clean the condenser coils with a coil brush.

Replace the KitchenAid condenser fan of the refrigerator: The fan is situated inside a machine compartment inside the KitchenAid refrigerator next to the compressor. It moves air across the condenser coils to help chill the refrigerant that is hot that is coming out of the compressor. The refrigerant is chilled prior to it moving through the expansion device before moving into the evaporator. If the fan in the condenser is not working properly, it should be replaced. Repair the KitchenAid refrigerator freezer defrost To improve heat exchange in the KitchenAid refrigerator’s auto defrost is able to melt the evaporator’s frost. The compressor shuts down and the heating element for defrost turns on. When defrosting, the frost melts off of the the evaporator fins. The condensate flows into the drip pan of an evaporator below the evaporator. Then it flows through a drainage tube and into the drain tray that is close to the compartment of the machine. The condensate evaporates out of the drain pan prior to the next defrost cycle. If the defrost doesn’t work, fix the problem.

Replace the KitchenAid refrigerator’s evaporator fan: The fan that evaporates is mounted on the evaporator assembly. It cools the cabinet by moving air over the evaporator fins. If the evaporator fan is defective, replace it. Repair the KitchenAid refrigerator thermostat control board. The temperature control board controls compressor and other components of the KitchenAid refrigerator. The tech sheet contains specific diagnostic methods to test the board. If it’s not working correctly or the temperature control board ceases working You can change it.

Replace the KitchenAid refrigerator thermostat temperature control thermostat: The thermostat is also known as the cold control thermostat or the cold thermostat and is located inside the control housing. It has a sensor tube that senses the temperature inside the KitchenAid refrigerator. The temperature control thermostat controls the temperature inside the cabinet through turning on and off the compressor according to the temperature detected by the sensor tube. If the thermostat fails to sense the temperature correctly or the compressor isn’t functioning properly, you should replace it. The KitchenAid refrigerator thermostat needs to be changed. If your refrigerator isn’t cooling as it should, the thermistor may be damaged. The thermostat receives temperature information from the thermistor. Therefore, a damaged thermistor might provide incorrect information.

Replace the KitchenAid refrigerator’s defrost timer: The defrost timer electronic device that controls the time between automatic defrost cycles. The motor that controls the defrost timer moves the control parts. The defrost motor stops when the contact points of the device enter the defrost state. When the compressor has stopped, the heater turns on for the specified time to melt frost off the fins of the evaporator. This allows for better exchange of heat between the evaporator and. After the time period for defrost ends the defrost timer’s contacts are reset to allow normal cooling operations within the KitchenAid refrigerator. If the heater for defrost stops functioning, you’ll need to replace it. Faulty contacts in the timer can cause the heater to not be energized in any way or to constantly be energized. In these instances it is recommended to replace the timer. Adjust the refrigerator or freezer doors Doors to freezers and refrigerators are hinged and swing, which can be damaged or bent. Doors can start to lose their shape and allow warm moist to flow into the refrigerator. This can cause excessive frost that can cause the drain tube or freezer to become frozen. Repairing the refrigerator involves the adjustment or replacement of the hinges in order to ensure that the doors function correctly and stay properly aligned. Repair the KitchenAid refrigerator’s door gasket. This attaches to the freezer or fridge door panel. It stops air from entering and leaving the cabinet when it is shut. A gasket that is damaged lets warm, moist air in the KitchenAid refrigerator even when the door is closed which can cause excessive frost and cooling issues. If the seal has become damaged or worn, replace it.

Replace the KitchenAid refrigerator’s electronic control board: Also known as the main board, or the power board (PCB) The electronic controlboard regulates the compressor, defrost cycle as well as other functions. If it detects that the compressor needs to be running to keep the refrigerator cool, it sends current to the compressor and fans. To monitor temperatures inside the refrigerator or freezer the electronic control panel receives signals from sensors for temperature. The electronic control boards controls the defrost cycles using this information. Diagnostic tests can be performed by the electronic control board in order to check its operation. While the exact method of testing will differ between models, the Forced Defrost is the one most commonly performed. You can find the instructions on how to run diagnostics in the tech sheet.

Replace the electronic control board if it’s not functioning correctly: Routine maintenance for KitchenAid fridges Clean refrigerator coils cause problems with the freezer and refrigerator’s ability to cool properly and run efficiently. To clean condenser coils, refer to the owner’s manual. Prior to cleaning the coils, disconnect the electrical outlet of your KitchenAid refrigerator. In most refrigerators the coils are located hidden behind the front grill on the bottom. Clean the condenser coils using the help of a coil brush. Regular maintenance involves replacing the water filter, removing the dust from the bottom of the grille as well as adjusting the hinges if doors aren’t sealing tightly.
