Evaporator Temperature Sensor / Switch: Description and Operation

GF83.57-P-2126GZ Evaporator Temperature Sensor, Component Description
- except CODE (582) Rear air conditioner

Component Identification:

Location
The evaporator temperature sensor is located on the left side of the A/C housing.

Task
The evaporator temperature sensor measures the temperature of the air flowing past the evaporator. The reading is read in directly by the AAC control and operating unit (N22) or comfort AAC control and operating unit (N22/7).

Function
The evaporator temperature sensor is a temperature-dependent resistor. Controlled regulation of the refrigerant compressor (A9e.) using the values received from the AAC control and operating unit or comfort AAC control and operating unit, prevents the evaporator from icing up.
