Question and Answers


Do I need a defrost timer or heater?


The best way to help determine what part is needed is to put this unit into a defrost cycle. It can be manually advanced by doing the following in order.

  1. Unplug the refrigerator
  2. Turn the thermostat off
  3. Reconnect the power (leave the thermostat off)
Within 3-8 seconds it will activate the heater. After a few minutes you should be able to hear some hissing and popping from inside the freezer. This is the ice melting on the heater. If you hear this, it means the ADC board (timer) # 4388931 is not advancing and will need to be replaced. If nothing happens the heater or bi-metal may have failed. When you advance it into the defrost cycle, listen for some clicks. If it clicks twice, the bi-metal may be open. To determine for sure between the bi-metal and element, some checks will need to be made. The bi-metal is usually the least common part that needs replacing. If you need more assistance, please resubmit your question with additional details.

Hi Scott: How would you solve the same problem on a Kenmore 106.52759100 refrigerator? I disconnected the bi-metal defrost and turned the refrigerator back on. It gets cold immediately and takes about 4 days before I have to defrost the refrigerator again. What does this tell you? Is the problem the bi-metal, the defrost element or the board? Thank you.
