High Temperature Cutout (HTC)

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.

Convection Fan and Ring Element

All models except the HBL33/HBN33 and the lower cavity of the

HBL56/HBN56 and HBL35/HBN35 models, which have a thermal

oven cavity, are configured with convection capabilities in the upper

and/or lower ovens. The HBL34/HBN34 and HBL35/HBN35 models

have a convection fan only, and the remaining models with convection

cavities have both a convection fan and a convection (also called a

rd"

"ring" or "3

) element, which gives the ovens true (or genuine

European) convection capability.

Depending on the cooking mode selected, the fan may be used, with

or without the ring element, to circulate heat evenly throughout the

cavity in various cooking modes.
