Jenn Air Refrigerator Troubleshooting. Any modern refrigerator is a complex system, where the majority of parts interact with each other. In case of damage to one part, the entire system can fall out if a breakdown is not corrected in time.
Typically, diagnosing a malfunctioning fridge causes further professional repairs unless you possess the skills necessary to handle those repairs on your own.
Jenn-Air manufactures high-end appliances, so a basic Jenn Air refrigerator typically has lots of innovative features, as well as an attractive design.
These fridges provide decent temperature performance and energy efficiency while the noise level is rather low.

In this article, we discuss how to troubleshoot Jenn air refrigerator problems.
Jenn Air Refrigerator Won’t Defrost
The main control board is responsible for regulating the power supply to the freezer and refrigeration compartments.
The main control board turns on and off various components of the refrigerator such as the compressor, defrost system, thermal protector, and evaporator fan motor.
If it malfunctions, it may stop sending voltage to the defrost system resulting in a failure in the system’s ability to work correctly, or even worse not work at all.
Mainboards are commonly misdiagnosed – before replacing them, first test all of the defrost system components.
The defrost heater assembly turns on several times throughout the day to melt away any frost that may have accumulated on the evaporator coils.
When there is a temperature drop in the refrigerator, a sensor within the freezer notifies the control board and it signals the defrost heater assembly to turn on, melting away any frost.
If the defrost heater assembly fails it will not defrost properly, allowing ice and frost to continue building up until it eventually blocks airflow.
To determine if the defrost system is malfunctioning use a multimeter or ice pick to test the continuity of both parts of the heating coil.
If neither part registers continuity then order a replacement coil assembly and repair it.
Jenn Air Refrigerator Won’t Cool
A refrigerator’s starter capacitor may not work, preventing the compressor from starting and preventing the refrigerator from cooling.
This can happen whenever the mainboard receives a signal to initiate cooling from the thermostat, but no cooling occurs.
In order for one to determine whether or not the capacitor is defective, he/she should test it with a multimeter. If it turns out that the start capacitor is indeed defective, then you should replace it with a new one.
The control board may also be having an issue. However, if all other components check out, then there’s a high chance that this mainboard is what needs replacing.
It’s recommended to unplug your appliance before beginning any repair work; also, during testing, make sure that you’re using an insulated or safety towel so you don’t get injured while carrying out repairs.
Jenn Air Refrigerator Makes A Lot Of Noise
Condenser fan motors are usually installed on refrigerators. It cools the refrigerant and sends cool air through the coils that cause it to expand and turn into cold air while removing the heat from your food.
If the fan is not working, you can try cleaning out any debris that might have gotten into the fan blades or perform a simple test to see if the unit is getting power by simply checking if it turns on when you press its switch located on an outside wall of your refrigerator.
The refrigerator’s fan blade may be malfunction if clamoring occurs. The condenser’s supporter may be impeded or high-temperature battle bearings.
The first percentage is the fan motor for free movement. If the backer doesn’t move freely, confer with jell’s assistance to see if there is a lightweight resting on it or something caught in it.
Additionally, survey the condenser’s supporter in the back underside of the refrigerator to determine if there is any contamination present that may be restraining it from turning normally.
Jenn Air Refrigerator Constantly Runs
Defrost timers may be defective on refrigerators that run constantly. A defrost timer turns on the defrost heater two to three times a day to melt any frost that has accumulated on the freezer evaporator coils. If the timer is defective, it won’t advance to turn on the heater.
The refrigerator’s door gasket may be defective or torn if it runs frequently. The gasket prevents heat from your kitchen from getting into your refrigerator, which keeps its contents cold.
Without a good seal between the door and the compressor compartment, warm air will drift into your refrigerator when it’s turned off.
This causes humidity in your kitchen to condense inside the fridge. Because it’s so wet, it freezes. The defrost timer usually clears this frost/ice within 24 hours, but if the door gasket is loose, ice can build up faster than the defrost cycle can catch up with it.
