Why Is My Jenn Air Freezer Not Cold Enough?

Jenn AIr freezers might not be cooling enough due to issues like defrost system failures and dirty condenser units. fan failures and leaky door gaskets. Although you may notice the cooling issue begin in the freezer, you’ll soon find the Jenn AIr refrigerator and freezer not cooling enough. To avoid food spoilage, you’ll need to quickly solve the issue. How to stop air leaks from keeping your Jenn AIr freezer too cold If your Jenn AIr freezer is too hot to keep the ice cream frozen or if you notice a lot of frost inside the freezer warm moist air may be leaking into your refrigerator.

Replace damaged gaskets and inspect the door gaskets. If the gaskets are in good shape but a door sags on its hinges, creating gaps between the door gasket and the cabinet around openings in the doors, you can adjust the hinges on the Jenn AIr refrigerator doors to ensure that the gaskets are sealed to the cabinet around the door openings. If frost accumulation is limited to the back freezer compartment wall, then the auto freeze system might be malfunctioning. The defrost system works well and melts off the frost from the coils of the evaporator each 8 hours to maintain clear air passages through the evaporator so that the refrigerator and freezer compartments can cool down effectively. The defrost mechanism that is automatic may fail and frost will accumulate on the evaporator and back freezer compartment walls. The accumulation of frost could block cooling air pathways through evaporator, causing Jenn AIr freezers to take longer time to cool down.

How to fix other issues that keep your freezer from getting sufficiently cold You should examine the cooling of the freezer compartment if the fan ceases to run. If the fan is not working then replace it. If the condenser coils aren’t clean, it can cause cooling issues. Unplug the Jenn AIr refrigerator and check the condenser coils for dust and dirt buildup. If they are dirty Clean the condenser tubes. Continue to clean the coils throughout routine Jenn AIr refrigerator maintenance. If the freezer doesn’t be cold enough, you must ensure that the condenser fan runs. The condenser will not cool refrigerant efficiently if the condenser fan doesn’t run. If the fan stops running when it is activated Replace it.

These fixes can help you Find the Solution to Your Refrigerator Issue

Replace the Jenn AIr refrigerator defrost sensor

The Jenn AIr refrigerator defrost sensor, also referred to as the bi-metal defrost termination thermostat-trips when it detects that the temperature of the evaporator becoming high enough to overheat. The sensor for defrost will go off when it senses that the temperature in the evaporator has been getting too high and shuts off the heater. If the defrost detector trips it turns off power to the heater. Over time, frozen ice can form on the evaporator’s fins and cause the fridge and freezer not cool properly. It is possible to use a an ohm/volt meter to test the defrost sensor’s continuity. If it does not show continuity at 0 degrees F then replace the defrost sensors. Clean the Jenn AIr condenser tubes of the refrigerator. The dusty Jenn AIr fridge coils can cause issues with the refrigerator’s cooling as well as efficiency. To clean condenser coils, consult the manual for the owner. Unplug the Jenn AIr refrigerator prior to accessing and cleaning the coils. The majority of Jenn AIr refrigerators have coils that are behind the grill on the bottom. By using a coil brush remove the condenser coils.

Replace the Jenn AIr refrigerator compressor condenser Fan

This fan is located in the machine compartment inside the Jenn AIr refrigerator next to the compressor. It circulates air across the fan coils of the condenser to cool the hot refrigerant that comes from the compressor. The refrigerant is chilled before it moves through the expansion device and into the evaporator. Replace any defective condenser fans.

Repair the Jenn AIr refrigerator defrost system

The Jenn AIr refrigerator automatic defrost system periodically melts frost from the evaporator in order to increase the exchange of heat. The compressor shuts down and the defrost heating elements are switched on. When defrosting, the frost melts from the evaporator fins. The condensate flows to an evaporator drip tray beneath the evaporator, and later flows through a defrost drain tube to a drain pan next to the compressor in the compartment of the machine. The condensate water evaporates out of the drain pan prior to the next defrost cycle. If the defrost doesn’t work, fix the problem. Replace the Jenn AIr refrigerator’s evaporator fan. The fan is connected to the evaporator. It circulates air through the cabinet and across the fins of the evaporator. If the fan in the evaporator is damaged, replace it.

Replace the Jenn AIr refrigerator temperature control board

The temperature control board, also called the electronic control board-is located in the machine compartment, close to the compressor behind a panel at the side of the Jenn AIr refrigerator. The temperature control board regulates the the compressor as well as other parts of the Jenn AIr refrigerator. It is able to be tested by following the diagnostic tests procedures found on the tech sheet of the refrigerator. Change the temperature control board in case it doesn’t function properly or isn’t regulating the components properly. Replace the Jenn AIr refrigerator thermostat temperature control thermostat. The thermostat is also known as the cold thermostat or cold thermostat and is located inside the housing for the control. The thermostat is equipped with an attached sensor tube it that detects the temperature inside the Jenn AIr refrigerator cabinet. The temperature control thermostat controls the temperature within the cabinet through turning it on and off the compressor based on the temperature sensed by the sensor tube. If it is unable to accurately measure temperature or fails to turn off the compressor, the temperature control thermostat should be replaced. The Jenn AIr refrigerator’s thermistor needs to be replaced. A broken thermistor could send bad temperature information to your thermostat.

Replace the Jenn AIr refrigerator defrost timer

The defrost timer can be described as an electronic device that regulates the time between automatic defrost cycles within the Jenn AIr refrigerator. The motor that drives the defrost control elements and runs them. If the contact contacts for defrost advance into the defrost cycles the compressor ceases to operate. The heater for defrost turns on for a set time to melt the frost off of evaporator fins. This allows for more efficient heat exchange between the evaporator and. After the timer expires, the thermostat’s contacts thermostat for defrost switch back to allow normal cooling for the Jenn AIr refrigerator. You’ll need to change the timer for defrost if it doesn’t advance when activated. The defrost heater can be prevented from being energized due to faulty contacts. In that instance, replace the timer for defrost. Adjust the freezer or refrigerator door: The refrigerator or freezer doors swing on hinges that can be damaged or bent. Over time the doors can start to lose their elasticity and allow warm, humid air to enter the freezer or refrigerator door that creates excessive frost that can eventually cause the drain tube to freeze. The refrigerator repair involves aligning and fixing the hinges in order to ensure they work correctly.

Replace the Jenn AIr refrigerator’s door gasket

This attaches to the fridge or freezer door panel. It stops air from entering and leaving the cabinet when it is shut. A damaged gasket lets warm, moist air into the Jenn AIr refrigerator even when the door is closed, causing excessive cooling and frost issues. If the seal on your door is broken or damaged, you should replace it. Replace the Jenn AIr refrigerator’s electronic control board. Also called the main board, or the power board (PCB), the electronic controlboard regulates the compressor, defrost cycle and other functions. It senses that the compressor in the refrigerator needs to be running to keep it cool and then sends out signals to the compressor’s fans. The control board’s electronic circuit also receives signals from temperature sensors to monitor the temperature within the freezer and refrigerator. With this information, the control board’s electronic circuitry controls the defrost process. Diagnostic tests can be done by the electronic control board in order to verify its operation. While the test may differ by model, the most common one is called the Forced Defrost. You can find the instructions for running tests in the tech sheet. Replace the electronic control board if it’s not functioning correctly.

Routine Jenn AIr refrigerator maintenance Clean the condenser heating coils according to your owner’s manual. Unplug the Jenn AIr refrigerator before accessing and cleaning the coils. The coils are located behind the refrigerator’s bottom front grill. They can be cleaned with the help of a coil brush. Regular maintenance involves changing the water filter, clearing dust off the bottom of the grille, as well as adjusting the hinges in case doors aren’t closing properly.
