HOW MICROWaVE 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 are like TV
waves or light waves You
can’t see them but you can
see what thev do
MIcrowaves pass through
glass, paper and plastic
without heating them so food
absorbs the energy Micro-
waves bounce off metal pans
so food does not absorb the
energy
Mod: Mixer
Mag;etron
Bottom
Oven Cavity
A magnetron produces
microwaves 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
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
Metal Floor
The 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
The mlcrowaves disturb
water molecules In the food
As the molecules bounce
around bumplng Into each
other, heat
IS
made, llke rub-
btng 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, when a cooking
time is set, when the oven is on, and when the temperature probe is plugged into Its
socket.
lo replace the light bulb:
1.
