Getting to Know Your
Microwave Oven
This section discusses the concepts behind microwave cooking. It also shows you the basics
you need to know to operate your microwave oven. Please read this information before you use
your oven.
How Your Kenmore Microwave Hood Combination Works
Microwave energy is not hot. It causes food to make
its own heat, and it is 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.
Metal floor
The glass turntable of your microwave oven lets
microwaves pass through. They then bounce off a
metal floor, back through the glass turntable, and are
absorbed by the food.
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.

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.

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
and make sure it latches.

Sensor Cooking
The Microwave System features Sensor Cooking
functions. A humidity sensor in the oven cavity detects
moisture and humidity emitted from food as it heats.
The sensor adjusts cooking times to various types
and amounts of food. Sensor cooking takes the
guesswork out of microwave cooking.
For the best cooking results
• Always cook food for the shortest cooking time
recommended. Check to see how the food is
cooking.
• 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.
• If you do not have a cover for a dish, use wax
paper, microwave-approved paper towels, or plastic
wrap. Remember to turn back a corner of the plastic
wrap to vent steam during cooking.
• Moving the receiver away from the microwave oven.
• Plugging the microwave oven into a different outlet
so that the microwave oven and receiver are on
different branch circuits.
Cook at 100% power for 1 minute. When the time is
up, the water should be heated.
