Thermal Fuse Removal and Replacement

When the range temperature reaches the maximum temperature
threshold, the thermal fuse breaks the electrical circuit in order to
protect the electronics from abnormally high heat conditions.
Some model ranges have thermal fuses installed, while other models
do not, as they are protected from adverse heat conditions by cavity
venting.
Thermal fuses are installed at the back of the range.
Be sure to check QuickFinder for relevant information, documentation,
and the correct part number when replacing this component.

1. Follow all safety precautions and steps in the Preparing the Range
for Servicing, page 21.
2. Remove the backguard (see Backguard and Island Trim Removal
and Replacement, page 73).
3. Remove the back panels (see Back Panel Removal and
Replacement, page 74).
4. Depending on the model range, you may have to remove the
crossmember cover (see Crossmember Cover Removal and
Replacement, page 75).

5. Detach the wire connectors from the terminals and make a note of
how the wires are connected.
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
6. Remove and retain the screw(s) securing the thermal fuse to the
range chassis.
7. Replace the thermal fuse if needed.
4.6.9 Manifold Arm Removal and Replacement – Back of Range
Figure 158: Typical Manifold Arm Models for Bake and Broil Burners
Accessible from the back of the range on 48-inch range models only,
the manifold arm is for bake and broil burners.
Although bake and broil components can be accessed and replaced
without removing the manifold arm, this procedure is provided if the
manifold arm needs to be replaced, for example, due to a gas leak in
the manifold arm, if the threading on the manifold arm is bad, or if
there is other damage to the manifold arm.
Be sure to check QuickFinder for relevant information, documentation,
and the correct part number when replacing this component.
