TIPS FOR MICROWAVE COOKING
BROWNING
Meat and poultry with high fat content cooked for at
least 10 to 15 minutes will brown lightly. Foods cooked
a shorter time can be brushed with a browning agent,
such as Worcestershire sauce, soy sauce, or barbecue
sauce.
COVERING
A cover will trap heat and steam and cause the food to
cook more quickly. Use a lid or microwave-safe plastic
wrap with one corner folded back to vent the excess
steam. Lids on glass casseroles can become hot
during cooking; always handle carefully. Waxed paper
will prevent the food from splattering in the oven and
help retain heat. When warming bread items, use
waxed paper, napkins, or paper towels. To absorb extra
moisture, wrap sandwiches and fatty foods in paper
towels.
SPACING
Arrange individual foods, such as baked potatoes,
cupcakes, and hors d’oeuvres in a circle and at least
1 inch apart. This will help the food cook more evenly.
STIRRING
Stirring blends flavors and redistributes the heat in
foods. Always stir from the outside toward the center
of the dish. Food at the outside of the dish heats first.
TURNING
Large foods, such as roasts and whole poultry, should
be turned so that the top and bottom cook evenly. Also
turn over chicken pieces and chops.
ARRANGEMENT
Do not stack food. Arrange in a single layer in the dish
for more even cooking. Because dense foods cook
more slowly, place thicker portions of meat, poultry,
fish, and vegetables toward the outside of the dish.
TESTING FOR DONENESS
Foods cook quickly in a microwave oven; test frequently
for doneness.
STANDING TIME
Food often needs to stand from 2 to 15 minutes after
being removed from the oven. Usually, you need to
cover food during standing time to retain heat. Remove
most foods when they are slightly undercooked and
they will finish cooking during standing time. The
internal temperature of food will rise about 10°F during
standing time.
SHIELDING
To prevent some portions of rectangular or square
dishes from overcooking, you may need to shield
them with small strips of aluminum foil to block the
microwaves. You can also cover poultry legs and
wing tips with foil to keep them from overcooking.
Always keep foil at least 1 inch from oven walls
to prevent arcing.
PIERCING
Pierce the shell, skin, or membrane of foods before
cooking to prevent them from bursting. Foods that
require piercing include yolks and whites of eggs, hot
dogs, clams, oysters, and whole vegetables, such as
potatoes and squash.

PRECAUTIONS
• Place the front surface of the door three inches or
more from the countertop edge to avoid accidental
tipping of the microwave oven during normal use.
• To program the oven, make sure you touch the center
of each pad firmly since the areas between the pads
will not activate the oven. A tone will sound each time
a pad is touched correctly. Do not touch several pads
at once.
• Do not strike the control panel with silverware,
cookware, etc. Breakage may occur.
• Always use caution when taking cookware out of the
oven. Some dishes absorb heat from the cooked food
and may be hot. See the “Cookware Guide” earlier in
this section for more information.
• Do not rinse cookware immediately after cooking. This
may cause breakage. Also, always allow the turntable
to cool before removing it from the oven.
• Never operate the oven when it is empty. Food or
water should always be in the oven during operation
to absorb the microwave energy.
• Do not use the oven to dry newspapers or clothes.
They may catch fire.
• Use thermometers that have been approved for
microwave oven cooking.
• The turntable must always be in place when you
operate the oven.
• Do not use your microwave oven to cook eggs in the
shell. Pressure can build up inside the shell, causing it
to burst.
• There are several precautions to follow when
microwaving popcorn:
— Do not pop popcorn, except in a microwave-safe
container or commercial packages designed for
microwave ovens.
— Never try to pop popcorn in a paper bag that is not
microwave-approved.
— Overcooking may result in smoke and fire.
— Do not repop unpopped kernels.
— Do not reuse popcorn bags.
— Listen while corn pops. Stop oven when popping
slows to 2-3 seconds between pops.
— Do not leave microwave unattended while popping
corn.
— Follow directions on bag.
CLEANING
NOTE: Before cleaning the oven, unplug the power
cord. If this is impossible, open the oven door to
prevent an accidental oven start.
INTERIOR
Wipe the oven inside and outside with a soft cloth and
a mild detergent solution. Then rinse and wipe dry. This
should be done weekly or more often, if needed. Never
use cleaning powders or rough pads.
Excessive oil splatters on the inside top will be difficult
to remove if left for many days. Wipe splatters with a
wet paper towel, especially after cooking chicken or
bacon.
REMOVABLE PARTS
The turntable and rotating ring are removable. They
should be hand-washed in warm (not hot) water with a
mild detergent and a soft cloth. Once they are clean,
rinse well and dry with a soft cloth. Never use cleaning
powders, steel wool, or rough pads.
• The turntable may be cleaned at the sink. Be careful
not to chip or scratch the edges as this may cause
the turntable to break during use.
• The rotating ring should be cleaned regularly.
DOOR
For best performance and safet
and the oven front frame should be free of food or
grease buildup. Wipe often with a mild detergent; then
rinse and wipe dr
rough pads.
