Function

2.1

Floor Heater Element

The floor heater element is located in the center of the oven cavity floor, and
prevents water from condensing and accumulating at the bottom of the oven cavity.
2.2 PT 1000 Temperature Sensor (R30 or R30/10)
The PT 1000 temperature sensor is a printed circuit board (PCB) which is
used to provide the electronic with data to calculate the oven cavity
temperature. The sensor's resistance increases as the temperature
increases. Details are listed in Table 030-2.
