Volkswagen Golf Service & Repair Manual: Temperature switch for evaporator -E33

Volkswagen Golf Service & Repair Manual / Air conditioning system with refrigerant R134a / General information on refrigerant circuit / Electrical components not installed in refrigerant circuit / Temperature switch for evaporator -E33

Function:

The temperature switch for evaporator -E33- senses the temperature between the cooling fins of the evaporator. It prevents the possibility of ice forming between the evaporator cooling fins by interrupting the current to the air conditioner compressor magnetic clutch if the temperature at the fins falls to the freezing point of moisture in the air.

The insertion depth of the sensor tube is marked on the device or is given in the repair manual → Rep. gr.87.
