How your microwave
oven works
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, radio waves
or light waves. You cannot see them, but you
can see what they do.
A magnetron in the microwave oven
produces microwaves. The microwaves
move into the oven where they contact
food as it turns on the turntable.
Microwaves pass through most glass,
paper, and plastics without heating them so
food absorbs the energy. Microwaves
bounce off metal containers so food does
not absorb the energy.
The microwaves disturb water molecules
in the food. As the molecules bounce around
bumping into each other, heat is made, like
rubbing your hands together. This is the heat
that does the cooking.

Radio interference
Using your microwave oven may cause
interference to your radio, TV, or similar
equipment. When there is interference,
you can reduce it or remove it by:
• Cleaning the door and sealing surfaces
of the oven.
• Adjusting the receiving antenna of the
radio or television.
• Moving the receiver away from the
microwave oven.
For the best
cooking results
• Always cook food for the shortest
cooking time recommended. Check to see
how the food is cooking. If needed, touch
the EASY MINUTE while the oven is
operating or after the cooking cycle is over
(see the “Using EASY MINUTE” section).
• Stir, turn over, or rearrange the food
being cooked about halfway through the
cooking time for all recipes. This will help
make sure the food is evenly cooked.
NOTE: Some cycles may have to be reset
if you have interrupted the cycle.
• If you do not have a cover for a dish,
use wax paper, or microwave-approved
paper towels or plastic wrap. Turn back a
corner of the plastic wrap to vent steam
during cooking.
Testing your
microwave oven
To test the oven put about 1 cup (250 mL) of
cold water in a glass container in the oven.
Close the door. Make sure it latches. Cook
at 100% power for 2 minutes. When the
time is up, the water should be heated.
