Supco EDT11 Adjustable Electronic Defrost Timer for Refrigerators & Freezers - Commercial & Home Appliance Repair

We replaced the thermistor (Unavailable) and the entire circuitry for the defrost timer with this timer (like the old time refrigerators) to control how much time it runs and the compressor and the defrost heaters. Mucked around a bit with the timer settings (for mine 6 hours cooling-25 minutes defrosting) and it works great. Display still shows the temperatures and everything else works. Display Temperatures in the freezer climb while defrosting, but everything stays frozen.
