Role:

  • The thermostat acts as the "brains" of the cooling system, a crucial component for the refrigerator to function correctly.

 How it works

  1. Sensing temperature: The thermostat contains a sensor (either mechanical or digital) that monitors the inside air temperature.
  2. Comparing to setpoint: It compares this sensed temperature to the desired temperature set by the user, typically through a dial or digital display.
  3. Activating the compressor:
    • If the temperature is too warm, the thermostat sends a signal to turn the compressor on, activating the cooling cycle.
    • Once the desired temperature is reached, the thermostat sends a signal to turn the compressor off, preventing overcooling.
  4. Maintaining efficiency: This on-and-off cycling helps the refrigerator use energy efficiently by only running the compressor when necessary, preserving food quality and lowering energy consumption.
