Cooling Fan Removal and Replacement

Some models use a cooling fan with a Hall Effect sensor attached,
which is a part of the cooling fan assembly. Other models use a
cooling fan with an air interlock switch installed (see Air Interlock
Switch Removal and Replacement, page 79).
Be sure to check QuickFinder for relevant information, documentation,
and the correct part number when replacing this component.
Sharp Component – Use Gloves
Use gloves when handling the cooling fan, as it has sharp edges

4. At the back of the range, detach the wire connectors from the
fan's Hall Effect sensor, and make a note of which wires are
connected to each of the two different terminals (see Figure 153,
page 78).
NOTE: It is always recommended to label and tag all wires, wire
connectors and harnesses prior to disconnecting them, so as to
correctly identify their connections/locations when re-assembling.
Alternatively, you can photograph the wire connections prior to
disconnecting (for example, with your mobile phone).
5. Remove and retain the two screws that secure the cooling fan
(mounting plate) onto the range chassis (see Figure 152).
6. Using gloves, remove the cooling fan.
