6.3 Oven High Temperature Cutout (HTC)

The resettable HTC is a normally closed 12VDC thermal switch that is

used to detect over-temperature conditions within the oven. It has a

connector that will interrupt the double line break (DLB) relay coil

voltage supply if the temperature reaches 185°C/365°F. When the

HTC switch opens, it breaks the line to the double line break (DLB)

relays, cutting off power to the elements.

With the latch plate removed, the HTC and the bracket it's mounted

on are visible to the left of the door latch/motor assembly. Figure 19

shows the HTC and bracket, but note that this view is looking from the

rear of the oven towards the front, beneath the top plenum.

6.3.1 Resetting and Replacing the HTC

of the interruption.

To reset the HTC...



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....*
