6.7 Temperature Sensor
The PT1000 temperature sensor is in the upper left corner of the
cavity, with two screws securing it. An ohmmeter can be used to
check the resistance of the sensor. Normal ranges (based on cavity
temperature) are shown in Table 4.
6.8 Control Module (Relay Board)
The control module controls the fans, door locks, lights, etc., regulates
temperatures, and monitor safety functions. The module is also
responsible for communication with other modules, analyzing sensor
data, regulating line voltage, and managing user interface activities.

2. Slide the range out of the cutout to get access to the rear of
the unit.

rear housing cover, then grasping both sides, pull the cover
downward and away from the range.
NOTICE
More than 75% of the control modules returned to the factory are fully
functional. Before diagnosing a bad control module, be sure to
disconnect and reconnect each wire/wire harness.
