Refer to Figure 3 while you read this section.
• A cooling fan, in the storage drawer area, is used to maintain
optimum temperatures in the console areas.
• Restrictions to the air flow in the cooling systems can cause prema-
ture failure of the controls or the thermal protectors.
The cooling fan draws air from inside the base of the cabinet. It
forces the air up the air channel, which is located under the left side
panel, to the opening at the end of the control panel chassis. Air then
flows across the chassis below the control panel, and cools it. Air
enters through the series of holes in front of the range top, flows be-
neath it, and exits to the outside through slots in the rear panel.
The cooling fan is operated by the cooling fan thermal switch, which
is located under the right side of the control panel, on the control
panel chassis.
When the control panel temperature exceeds 104˚F, the thermal
switch will close and turn ON the cooling fan.
When the control panel chassis temperature drops below the turn-on
point, the thermal switch opens, and turns the cooling fan off.
