GENERAL INFORMATION

	Microwave Features
Defrost	Assisted Cooking

The Defrost feature can be used, or the microwave oven can be manually set to defrost by using 20% cook power.

Unwrap foods and remove lids (from fruit juice) before defrosting. Remove any metal twist-ties and replace them with strings or elastic bands.

If food is foil wrapped, remove foil and place it in a suitable container.

Slit or pierce plastic pouches or packaging. Slit the skins, if any, of frozen food such as sausage.

Bend plastic pouches of food to ensure even defrosting.

Always underestimate defrosting time. If defrosted food is still icy in the center, return it to the microwave oven for more defrosting.

The length of defrosting time varies according to how solidly the food is frozen.

Shallow packages will defrost more quickly than deep blocks.

Separate food pieces as soon as possible during or at the end of a cycle for more even defrosting.

Foods left outside the freezer for more than 20 minutes or frozen ready-made food should not be defrosted using the

Custom Defrost feature, but should be defrosted manually.

Use small pieces of aluminum foil to shield parts of food such as chicken wings, leg tips and fish tails. See the “Aluminum Foil and Metal” section first.

Steam Cook

Steam Cook is a sensor cooking function that uses microwaves to steam food. Use Steam for foods such as vegetables, fish and potatoes.

Times and cooking powers have been preprogrammed for steaming a number of food types.

Use a microwave-safe steamer.

Use 1/2 cup (125 mL) water or as directed in the steamer instructions.

Popcorn

NOTE: During Popcorn function, as with all microwave cooking functions, the microwave oven should be attended at all times.

Listen for popping to slow to one pop every 1 or 2 seconds, then stop the cycle.

To avoid damage to the microwave oven, do not use regular paper bags or glass utensils.

Pop only one package of popcorn at a time.

Follow manufacturer’s instructions when using a microwave popcorn popper.

For best cooking results, do not try to pop unpopped kernels.Use fresh bags of popcorn for optimal results.

Cooking results may vary by brand and fat content.

The microwave oven uses the sensor to determine sizes that can be popped: 1.75–3.5 oz (50–99 g) bags.

Scroll through the Assisted Cooking menu until the desired food selection is reached.

Follow the prompts on the screen to customize the settings for Assisted Cooking.

The microwave oven sensor adjusts the cooking times and power levels for various foods and quantities.

NOTE: The microwave oven may prompt user to input weight to help optimize the settings.

Favorites

The Favorites feature stores the microwave settings for your favorite recipe.

NOTE: A select set of Favorites and suggestions may be automatically shown on the Home screen based on your meal times.

To save a recipe, select the Favorites keypad (heart icon), and follow the prompts on the screen to customize your favorites. Add an image or name to the favorite to customize it to your preferences.

Preheating and Oven Temperature

Preheating

When beginning a Bake, Convect Bake, or Convect Roast cycle, the oven will begin preheating after Start is pressed. The oven will take approximately 12 to 17 minutes to reach 350°F (177°C) with all of the oven racks provided with your oven inside the oven cavity. Higher temperatures will take longer to preheat. The preheat cycle rapidly increases the oven temperature. The actual oven temperature will go above your set temperature to offset the heat lost when your oven door is opened to insert food. This ensures that when you place your food in the oven, the oven, will begin at the proper temperature. Insert your food when

the preheat tone sounds. Do not open the door during preheat before the tone sounds.

Rapid Preheat

Rapid Preheat can be used to shorten the preheating time. Only one standard flat oven rack should be in the oven during Rapid Preheat. Extra racks should be removed prior to starting. The preheating cycle should be completed before placing food in the oven. When the Rapid Preheat cycle is complete, the oven starts a normal Bake cycle.

IMPORTANT: Rapid Preheat should be used only for one-rack baking.

Oven Temperature

While in use, the oven elements will cycle on and off as needed to maintain a consistent temperature, but they may run slightly hot or cool at any point in time due to this cycling. Opening the oven door while in use will release the hot air and cool the oven which could impact the cooking time and performance. It is recommended to use the oven light to monitor cooking progress.

NOTE: On models with convection, the convection fan may run in the non-convection bake mode to improve oven performance.

Whirlpool® Smart Wall Ovens n 1-9

GENERAL INFORMATION

Baking and Roasting

IMPORTANT: The convection fan and convection element may operate during the Bake function to enhance performance and heat distribution.

The oven will take approximately 12 to 17 minutes to reach 350°F (177°C) with all oven racks inside the oven cavity. The preheat cycle rapidly increases the temperature inside the oven cavity. Higher temperatures will take longer to preheat. Factors that impact preheat times include room temperature, oven temperature, and the number of racks. Unused oven racks can be removed prior to preheating your oven to help reduce preheat time. The actual oven temperature will go above the set temperature to offset the heat lost when the oven door is opened to insert food. This ensures that the oven will begin at the proper temperature when you place food in the oven. Insert food when the preheat tone sounds. Do not open the door during preheat until the tone sounds.

During baking or roasting, the bake and broil elements will cycle on and off in intervals to maintain the oven temperature.

Depending on the model, if the oven door is opened during baking or roasting, the heating elements (bake and broil) will turn off approximately 30 seconds after the door is opened. They will turn on again approximately 30 seconds after the door is closed.

Frozen Bake™

Frozen Bake™ Technology automatically adjusts the manufacturer’s bake time by combining preheating and baking to deliver great packaged frozen food results without the wait. There are multiple preprogrammed food options. The Frozen Bake™ cycle have been customized to work only with these foods. When using Frozen Bake™ Technology, it is important that you follow all manufacturer’s instructions including venting, covering, stirring or placing on a baking sheet to ensure a good result. When cooking frozen meals, only cook items that provide instructions for cooking in a conventional oven. Place your dish in the center of the rack and select one of the rack positions recommended for Frozen Bake™ in the “Positioning Racks and Bakeware” section and bake only one package or pan at a time. Use the temperature and maximum bake time from the package.

A tone will alert you to check the food for doneness before the cook time is complete and again at the end of the cook time. The display will prompt you to add additional cook time if needed.

Broiling

When broiling, no preheating is necessary unless recommended otherwise in the recipe. Position food on grid in a broiler pan, and then place it in the center of the oven rack. Close the oven door to ensure proper broiling temperature.

NOTE: Odors and smoke are normal the first few times the oven is used or if the oven is heavily soiled.

Changing the temperature when broiling allows more precise control when cooking. The lower the broil setting, the slower the cooking. Thicker cuts and unevenly shaped pieces of meat, fish and poultry may cook better at lower broil settings. Place the food in the lower oven. Refer to the “Positioning Racks and Bakeware” section for more information.

On lower settings, the broil element will cycle on and off to maintain the proper temperature.

For best results, use a broiler pan and grid. It is designed to drain juices and help avoid spatter and smoke.

If you would like to purchase a broiler pan, one may be ordered. Please refer to the “Accessories” section for more information.

Convection Cooking

In a convection oven, the fan-circulated hot air continually distributes heat more evenly than the natural movement of air in a standard thermal oven. This movement of hot air helps

maintain a consistent temperature throughout the oven, cooking foods more evenly, crisping surfaces while sealing in moisture and yielding crustier breads.

During convection cooking, the bake, broil and convection (true convection only) elements cycle on and off in intervals to maintain the oven temperature, while the fan circulates the hot air.

If the oven door is opened during convection cooking, the fan will turn off immediately. It will come back on when the oven door is closed.

NOTE: The oven door must be closed for convection broiling.

Position the racks according to the “Positioning Racks and Bakeware” section before starting convection cooking.

With convection cooking, most foods can be cooked at a lower temperature for a shorter length of time. These adjustments can be made using the following chart.

Setting Guidelines

Convect Bake Reduce the standard baking temperature 25°F (15°C).

Convect Roast Use standard recipe temperature. Cooking time may be reduced by 15% to 30%

with Convect Roast so the food should be checked for doneness early.

Convect Broil Use standard recipe temperature. Cooking time may be reduced so the food should be checked for doneness early.

Convert Time/Temp

Convection temperatures and times differ from those of standard cooking. The Convert Time/Temp convection feature is a function that converts a standard thermal bake or roast cook time and temperature into an ideal cook time and temperature for convection cooking. The displayed time and temperature will be the converted for convection values.

1-10 n Whirlpool® Smart Wall Ovens

GENERAL INFORMATION

Temperature Probe

The temperature probe accurately measures the internal temperature of meat, poultry and casseroles with liquid and should be used in determining the doneness of meat and poultry.

The temperature probe should only be used with Bake, Convect Bake, or Convect Roast.

Always unplug and remove the temperature probe from the oven when removing food.

To Use:

Before using, insert the probe into the food item. For meats, the probe tip should be located in the center of the thickest part of the meat and not into the fat or touching a bone. Place food in oven and connect the temperature probe to the jack. Keep probe as far away from heat source as possible. Close oven door.

NOTE: The temperature probe must be inserted into the food item before the mode is selected.

Use the Assisted Cooking feature for guidance and step by step instructions on inserting the probe and selecting target food internal temperatures

Plug the probe into the oven’s port or pick the Probe icon in the Tools Menu. Both will show a pop-up that allows user to pick the cooking mode and all of the options. Place food in the oven and connect the temperature probe to the jack.

Keep the probe as far away from the heat source as possible.

Close the oven door.
