Evaporator Temperature Sensor / Switch: Description and Operation
GF83.57-P-2126TX Evaporator Temperature Sensor Component Description
Component Identification
Location
The evaporator temperature sensor is located at the left on the A/C housing.
Task
The evaporator temperature sensor records the temperature of the air flowing past the evaporator. The reading is read in directly by the AAC [KLA]
control and operating unit (N22) (without code (581) comfort automatic air conditioning) or from the comfort AAC control and operating unit (N22/7)
(with code (581) comfort automatic air conditioning).
Function
The evaporator temperature sensor is a temperature-dependent resistor. The values transmitted to the AAC [KLA] control and operating unit or the
comfort AAC control and operating unit enable the refrigerant compressor (A9) to be specifically regulated to prevent the evaporator from freezing.
