Temperature switch for evaporatorE33

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.
