HOW MICR-
OVENS
WORK
Microwave ovens are safe. Microwave energy is not hot. It causes food to
make Its own heat, and it’s this heat that cooks the food.
Microwaves ore like TV
waves or lrght waves You
can’t see them, but you can
see what the\ do
Microwaves pass through
glass, paper and plastic
without heating them so food
absorbs the energy. Mtcro-
waves bounce off metal pans
so food does not absorb the
energy

Metal iloor
A magnetron produces
mrcrowaves. The microwaves
move into the oven where
they are scattered around by
a stirrer (like a fan).
Microwaves bounce off
metal oven walls and are
absorbed by food
lne bottom of your micro-
wave oven lets micro-
waves through. Then they
bounce off the metal
floor, back through the
bottom, and are ab-
sorbed by the food
Microwaves may not reach
the center of a roast. The heat
around the outside is what
cooks the roast all the way
through. This IS one of the
reasons for letting some
foods (roasts, baked pota-
toes] stand for a while after
cooking, or for stirring some
foods during the cooking
time.
The microwaves disturb
water molecules in the food.
As the molecules bounce
around bumping into each
other. heat is made, like rub-
bing your hands together.
This is the heat that cooks.
THE MICROWAVE OVEN LIGHT
The light in the microwave oven comes on when the door is
open and when the
oven is operating.
To replace the light bulb:
1. Move range away from the wall. Be very
careful. It Is heavy.
2. Unplug the power cord.
3. Remove holding screw on access panel.
4. Remove the cardboard baffle from the bulb.
5. Replace the bulb with a 40-watt appliance
bulb.
6. Replace the cardboard baffle and the ac-
cess panel
7. Plug in the power cord and move the range
back into position.
