AIR FLOW

Air passes through the oven door by a combi-

nation of natural and forced convection. Air

enters the door through the bottom slots, and

passes between the outer glass, and the angled

inner glass. This air exits through the top slots

in the door via natural convection. Air also

enters the bottom of the door, and is drawn

between the two pieces of inner door glass,

where it exits through the top slots in the upper

part of the door. This air is then drawn into the

blower, and is forced down the back of the unit

between the inner and outer chassis covers,

and finally out the bottom vent.

The purpose of the convection fan is to circu-

late hot air inside the oven cavity, not to evacu-

ate the air. Thus, the air flow for the convection

models and the non-convection models, is the

same.

PRODUCT OPERATION

Intake air is drawn into the oven at two loca-

tions: through the control panel vent, (over the

latch assembly and the inner chassis top), and

through the side mounting rails (over the oven

sides and around the back). Air also enters the

oven at the back through the openings on the

upper section of the rear cover. At this point,

the air from the sides and the top mix. The air

is then pulled through the blower, down the

back of the unit between the outer and inner

rear covers, and out the front of the unit via the

bottom vent trim.

Air from the blower is forced over the cavity

vent. The pressure differential causes air to be

drawn from the cavity, where the air exits

through a small opening on the left side of the

control panel vent.
