Thermistors
This main control board uses input from 3 thermistors. These thermistors are located in the fresh
food section, the freezer section, and on the evaporator. The main control board monitors the
thermistors to determine the temperature in these areas of the unit and determines which
components to run and when to run them, based on this information.
