Troubleshooting a JennAir Freezer Not Cold Enough

#1 Freezer Not Cold Due to Dirty Condenser Coils

Is your JennAir freezer not cold enough? Try checking the condenser coils. The coils must dissipate heat for the freezer to stay cold. When they get dirty, the heat can no longer escape. This forces your refrigerator to work overtime and leads to a JennAir freezer warm issue.

If the condenser coils are located behind or underneath the unit, they are exposed to dirt, dust, pet hair, and debris. For this reason, coils need to be cleaned to work properly and help your freezer maintain the optimal temperature setting.

Expert technicians and manufacturers recommend that homeowners clean condenser coils every 6-12 months as part of a regular maintenance routine. If you know it’s been longer than 6 months since the condenser coils have been cleaned, your refrigerator is overdue for some attention.

Once the condenser coils are clean, wait a full 24 hours for the refrigerator to return to the correct temperature.

#2 Freezer Temperature Not Low Enough

When you have a JennAir freezer not cold enough and you have already cleaned the condenser coils, you should check the temperature set point. Refer to your owner’s guide for the recommended temperature setting for your unit.

Another reason behind a JennAir freezer not freezing sufficiently can be a faulty temperature control thermostat. Rotate the thermostat from the lowest to the highest setting and listen for a “click.” If you do not hear the click, the thermostat may be defective and should be tested by a certified JennAir repair technician.

#3 Freezer Warm Because Evaporator Coils Frosted Over

A JennAir freezer not cold enough may be due to evaporator coils that have frosted over. The most likely cause of this problem is a failed defrost system within the freezer. The defrost heater kicks on and off throughout the day to eliminate any frost that has accumulated on the coils. If the defrost system fails, the frost continues to build up and the coils will eventually frost over.

You can use a multimeter to test the defrost system for continuity. If the defrost heater does not have continuity, it needs to be replaced. For replacements or revisions, you can call us and thus schedule an appointment with some of our Jennair experts.
