The HTC is a normally closed switch which will interrupt the relay
supply voltage in the event of a high-temperature event caused by a
malfunctioning control module.
The HTC is located in the plenum, behind and to the left of the MDL.
Although it cannot be easily removed or replaced, a screwdriver can
be used to reach the reset button located on the top center of the HTC
after the latch plate has been removed.
