Temperature Sensors; Door Switches - Electrolux FROST REFRIGERATORS with ERF2021 electronic Service Manual

3 sensors are used to detect the various temperatures:
cooler air temperature sensor A (located on the cooler cell)
freezer air temperature sensor B (located on the freezer cell)
room ambient sensor C (
The wires leading from sensors A and B are encapsulated in foam inside the cabinet. As a result, these
sensors are not replaceable.
Sensor C is mounted on the display board.
Note:
The freezer air temperature sensor B is not used to control the appliance but only to display the freezer
compartment temperature.
The battery evaporator defrosting is driven by the electronic board and depends also on the detection of the
opening of the cooler and freezer door by using:
magnetic switch for the cooler door control (located on the display board inserted into the work top)
button for the freezer door control (located on the left side of the cold module).
The magnetic switch for the cooler door control is activated by a magnet located inside the cooler door.
Note:
The cooler door button is located under the work top and controls only the switching on and off of the lamp.
