Technical Information
4.2.2

Cooling Air Intake

Refer to Figure 4-2 – Cooling and Vapor Ducting. The cooling fan (Item 1)
draws in air through the vented openings in the appliance. The incoming
air is used to cool the appliance, the electrical components and the
surrounding cabinet on all sides.
4.2.3

Cooling Air and Vapors Path

Refer to Figure 4-2 – Cooling and Vapor Ducting. The cooling fan moves
air into the back area of the appliance (Item 2) passing over the
magnetron; and then is directed back toward the front of the appliance
and exits from the front of the appliance.
4.2.4

Air-Path During Microwave Operation

Refer to Figure 4-2 – Cooling and Vapor Ducting. The release element
(Item 4) opens, permitting a small amount of air-flow to mix with vapors in
the oven cavity. The air/vapor mix is directed through the cavity port
(Item 6) to the vent (Item 7). The air/vapor mix, again mixes with cooling
air.
Service Tip:
Should the air vent not open, air cannot exit and moisture will accumulate
in the oven cavity.
4.2.5

Air-Path During Convection, Broiler and Combination

Refer to Figure 4-2 – Cooling and Vapor Ducting. The air vent (Item 5)
remains closed. Vapors move via the cavity port (Item 6) to the vent (Item
7) and mix with cooling air.
4.2.6

Cooling Air and Vapor Exit

Cooling air and vapors are directed out of the appliance through the vent
above the air guide in the front of the appliance.
4.2.7

Cooling Fan (Coast-Down)

The cooling fan operates during the cooling phase and protects the
appliance from high temperatures and moisture. It shuts off when the
temperature in the oven cavity reaches about 158°F (70°C).
