One possible cause of a frost free fridge freezer freezing up is a faulty defrost timer. The defrost timer controls the timing and duration of the defrost cycle in the appliance. If the defrost timer malfunctions or gets stuck in the defrost mode, it can cause excessive frost buildup in the freezer compartment.
When the defrost timer is working correctly, it switches between the cooling and defrost mode at regular intervals. During the defrost mode, the compressor and fans are turned off, and a heating element is activated to melt any frost that has accumulated on the cooling coils. After a predetermined amount of time, the defrost timer switches back to the cooling mode, and the compressor and fans start operating again.
If the defrost timer gets stuck in the defrost mode, the cooling coils will not be able to maintain their normal temperature. This can lead to a buildup of frost on the coils, which in turn can interfere with the proper airflow and temperature regulation inside the freezer compartment. Eventually, this can cause the entire freezer to freeze up.
To determine if the defrost timer is faulty, you can manually advance it to see if it switches between the cooling and defrost modes. If the timer does not advance or gets stuck in either mode, it may need to be replaced.
Replacing the defrost timer should be done by a qualified technician, as it involves electrical connections and can be complex. They will ensure that the correct part is installed, and that it is compatible with your specific appliance model.
How to manually advance the defrost timer:
- Locate the defrost timer in your appliance. It is usually found behind the front kickplate, inside the control panel, or in the refrigerator compartment.
- Using a flathead screwdriver, turn the timer clockwise until you hear a click or feel resistance. This should advance the timer to the next mode.
- Listen for the sound of the compressor and fans turning off, indicating that the defrost mode has been activated. Wait for a few minutes to see if the timer switches back to the cooling mode.
- If the timer does not advance or switches back and forth rapidly, it is likely faulty and needs to be replaced.
Remember, a faulty defrost timer can cause frost buildup and freezing in your frost free fridge freezer. If you suspect a faulty defrost timer, it’s best to consult a professional technician to diagnose and resolve the issue.
