1. Open the temperature sensor housing by
removing the four nuts from the bottom and
then removing the five bottom disks. Refer to
Figure 7 for details on sensor housing
disassembly.
2. Label the wires connected to the temperature
sensor board and then disconnect the cable
from the sensor terminal block in the
