Air outlet temperature sensor for the evaporatorG263 or Evaporator temperature sensorG308

Air outlet temperature sensor for the evaporator -G263- or Evaporator temperature sensor -G308-

Operation:

The Air outlet temperature sensor for the evaporator -G263- or the Evaporator temperature sensor -G308- checks the evaporator's temperature. This value is transmitted to the air conditioning control device, which relies on it as a reference signal to regulate the air conditioning compressor. This prevents the evaporator from freezing.
