MAGNETRON BLOWER ASSEMBLY
During microwave operation room air is drawn in
through the front grille (air inlet tunnel) and down
into the magnetron blower area. The magne-
tron fan blows the cool air through, and around
the magnetron tube. The air then passes through
the damper door assembly (damper door is open
during microwave operation) into the oven cav-
ity.
As air enters the oven cavity, pressure builds up
inside, forcing hot air out the top of the oven (see
illustration below). The air passes through the
air tunnel outlet, across the humidity sensor and
back into the room.
