GF83.57-P-2126RT Evaporator Temperature Sensor, Component Description
Component Identification
Location
The evaporator temperature sensor is located on the left side of the air conditioner 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 (A9) using the values
received from the AAC control and operating unit or comfort AAC control and operating unit, prevents the evaporator from icing up. The refrigerant
compressor is switched off at an evaporator temperature of 2 degrees Celsius.
