Resetting and Replacing the HTC

Always troubleshoot a tripped HTC to determine the underlying cause
of the interruption.
To reset the HTC...
1. Remove power to the oven.
2. Insert a flat blade screwdriver through one of the vent slots,
and depress the red reset button.
3. Restore power and test operation.

NOTICE
The HTC switch should only be reset once or twice before being
replaced. The switch weakens each time it trips, so it will become
easier and easier for the switch to trip during high-temperature cycles
(i.e., Self-clean) if it has weakened over time.
To remove the HTC from the front, a right-angled screwdriver will be
needed....
1. Remove power to the oven.
2. First remove the latch plate and remove or slide the
latch/motor assembly aside as described in the Replacing the
Latch/Motor Assembly section.
3. Using a right-angled screwdriver, remove the two screws
securing the HTC to its mounting bracket.
 If it is not possible to complete step 3 from the front,
continue with step 4.
 If the screws were successfully removed, skip to step
9.
4. Remove the screws securing the right and left side trim pieces
to the cabinetry, and set screws aside.
