Cooking Controls

Power Level
The power level may be entered or changed immediately after entering the feature time for Cook Time, Time Defrost, Add 30 Sec or Express Cook. the power level may also be changed during the time countdown.
Variable power levels add flexibility to microwave cooking. The power levels on the microwave oven can be compared to the surface units on a range. Each power level gives you microwave energy a certain percent of the time. Power level 7 is microwave energy 70% of the time. Power level 3 is energy 30% of the time. Most cooking will be done on HI which gives you 100% power.
Power Level 10 will cook faster but food may need more frequent stirring, rotating or turning over. A lower setting will cook more evenly and need less stirring or rotating of the food.
Some foods may have better flavor, texture or appearance if one of the lower settings is used. Use a lower power level when cooking foods that have a tendency to boil over, such as scalloped potatoes.
Rest periods (when the microwave energy cycles off) give time for the food to “equalize” or transfer heat to the inside of the food. An example of this is shown with power level 3—the defrost cycle. If microwave energy did not cycle off, the outside of the food would cook before the inside was defrosted.
Here are some examples of uses for various power levels:
Power Level 10: Fish, bacon, vegetables, boiling liquids.
Power Level 7: Gentle cooking of meat and poultry; baking casseroles and reheating.
Power Level 5: Slow cooking and tenderizing for stews and less tender cuts of meat.
Power Level 3: Defrosting; simmering; delicate sauces.
Power Level 1: Keeping food warm; softening butter.
Cook Time I
Allows you to microwave for any time up to 99 minutes and 99 seconds.
Power level 10 (high) is automatically set, but you may change it for more flexibility.
1. Press Cook Time.
2. Enter cooking time.
3. Change power level if you don’t want full power. (Press Power Level. Select a desired power level 1–10.)
4. Press Start/Pause.
You may open the door during Cook Time to check the food. Close the door and press Start/Pause to resume cooking.
Cook Time II
Lets you change power levels automatically during cooking. Here’s how to do it:
1. Press Cook Time.
2. Enter the first cook time.
3. Change the power level if you don’t want full power.
(Press Power Level. Select a desired power level 1–10.)
4. Press Cook Time again.
5. Enter the second cook time.
6. Change the power level if you don’t want full power.
(Press Power Level. Select a desired power level 1–10.)
7. Press Start/Pause.
At the end of Cook Time I, Cook Time II counts down.
Time Defrost
Time Defrost allows you to defrost for a selected length of time. See the Defrosting Guide for suggested times. (Weight Defrost is explained in the Auto Feature section.)
When the oven signals, turn food over and break apart or rearrange pieces for more even defrosting. Shield any warm areas with small pieces of foil. The oven will continue to defrost if you don’t open the door and turn the food.
Power level is automatically set at 3, but can be changed. You can defrost small items quickly by raising the power level after entering the time. Power level 7 cuts the total defrosting time in about half; power level 10 cuts the total time to approximately 1/3. However, food will need more frequent attention than usual.A dull thumping noise may be heard during defrosting. This is normal when oven is not operating at High power.
Defrosting Tips
Weight Defrost
Weight defrost automatically sets the defrosting times and power levels to give even defrosting results for meats, poultry and fish weighing up to six pounds.
(Time Defrost is explained in the Time Features section.)
There is a handy guide located on the inside front of the oven.
Conversion Guide

Express Cook
This is a quick way to set cooking time for 1 –6 minutes.
Press one of the Express Cook pads (from 1 to 6) for 1 to 6 minutes of cooking at power level 10. For example, press the 2 pad for 2 minutes of cooking time.
The power level can be changed as time is counting down. Press POWER LEVEL and enter 1–10.
Add 30 Sec
You can use this feature two ways:
Humidity Sensor
The Sensor Features detect the increasing humidity released during cooking. The oven automatically adjusts the cooking time to various types and amounts of food.
Do not use the Sensor Features twice in succession on the same food portion—it may result in severely overcooked or burnt food. Be sure to let the oven cool down for 5-10 minutes before starting the next sensor cook.
If food is undercooked after the countdown, use Cook Time for additional cooking time.



Arcing
Arcing is the microwave term for sparks in the oven. Arcing is caused by:
Covering
Covers hold in moisture, allow for more even heating and reduce cooking time. Venting plastic wrap or covering with wax paper allows excess steam to escape.
Shielding
In a regular oven, you shield chicken breasts or baked foods to prevent over-browning. When microwaving, you use small strips of foil to shield thin parts, such as the tips of wings and legs on poultry, which would cook before larger parts.
Standing Time
When you cook with regular ovens, foods such as roasts or cakes are allowed to stand to finish cooking or to set. Standing time is especially important in microwave cooking. Note that a microwaved cake is not placed on a cooling rack.
Venting
After covering a dish with plastic wrap, you vent the plastic wrap by turning back one corner so excess steam can escape.
An occasional thorough wiping with a solution of baking soda and water keeps the inside fresh. Be certain the oven control is turned off before cleaning any part of this oven.

Walls, Floor, Inside Window, Metal and Plastic Parts on the Door
Some spatters can be removed with a paper towel; others may require a damp cloth. Remove greasy spatters with a sudsy cloth, then rinse with a damp cloth. Do not use abrasive cleaners or sharp utensils on oven walls.
To clean the surface of the door and the surface of the oven that come together upon closing, use only mild, nonabrasive soaps or detergents using a sponge or soft cloth. Rinse with a damp cloth and dry.
Never use a commercial oven cleaner on any part of your microwave.

Removable Turntable and Turntable Support
To prevent breakage, do not place the turntable into water just after cooking. Wash it carefully in warm, sudsy water or in the dishwasher. The turntable and support can be broken if dropped. Remember, do not operate the oven in the microwave mode without the turntable and support seated and in place.

Do not use cleaners containing ammonia or alcohol on the microwave oven. Ammonia or alcohol can damage the appearance of the microwave.
Case
Clean the outside of the microwave with a sudsy cloth. Rinse with a damp cloth and then dry. Wipe the window clean with a damp cloth.
Control Panel and Door
Wipe with a damp cloth. Dry thoroughly. Do not use cleaning sprays, large amounts of soap and water, abrasives or sharp objects on the panel—they can damage it. Some paper towels can also scratch the control panel.
Door Surface
It is important to keep the area clean where the door seals against the microwave. Use only mild, non-abrasive detergents applied with a clean sponge or soft cloth. Rinse well.
Power Cord
If the cord becomes soiled, unplug and wash with a damp cloth. For stubborn spots, sudsy water may be used, but be certain to rinse with a damp cloth and dry thoroughly before plugging cord into outlet.
Stainless Steel (on some models)
Do not use a steel-wood pad; it will scratch the surface.
To clean the stainless steel surface, use a hot, damp cloth with a mild detergent suitable for stainless steel surfaces. Use a clean, hot, damp cloth to remove soap. Dry with a dry, clean cloth. Always scrub lightly in the direction of the grain.
