Oven Vent

How to Set the Oven for Broiling

Your oven is vented through ducts at the rear of the range. Do not block these ducts when cooking in the oven—it is important that the ﬂow of hot air from the oven and fresh air to the oven burner be uninterrupted. Avoid touching the vent openings or nearby surfaces during oven or broiler operation—they may become hot.

Handles of pots and pans on the cooktop may

• become hot if left too close to the vent.

Do not leave plastic or ﬂammable items on the

• cooktop— they may melt or ignite if left too close to the vent.

Do not leave closed containers on the cooktop.

• The pressure in closed containers may increase, which may cause them to burst.

Metal items will become very hot if they are left on

• the cooktop, and could cause burns.

How to Set the Oven for Baking or Roasting

For many foods, internal food temperature is the best test for doneness. The temperature probe takes the guesswork out of cooking foods to the exact doneness you want.

Use of probes other than the one provided with this product may result in damage to the probe.

Use the handles of the probe and plug when inserting and removing them from the food and outlet.

To avoid damaging your probe, do not use tongs

• to pull on the cable when removing it.

To avoid breaking the probe, make sure food is

• completely defrosted before inserting.

To prevent possible burns, do not unplug the probe

• from the outlet until the oven has cooled.

Never leave your probe inside the oven during a

• self-cleaning cycle.

Do not store the probe in the oven.

•

After preparing the meat and placing it on a trivet or on the broiler pan grid, follow these directions for proper probe placement.

Insert the probe completely into the meat. It should not touch the bone, fat or gristle.

For roasts with no bone, insert the probe into the meatiest part of the roast. For bone-in ham or lamb, insert the probe into the center of the lowest large muscle.

Insert the probe into the center of dishes such as meat loaf or casseroles.

Insert the probe into the meatiest part of the inner thigh from below and parallel to the leg of a whole turkey.

Using the Convection Oven

The convection oven fan shuts off when the oven door is opened. DO NOT leave the door open for long periods of time while using convection cooking.

To help you understand the difference between convection bake and roast and traditional bake and roast, here are some general guidelines.

Convection Bake

Preheat the oven. See the Using the Oven–

• Preheating and Pan Placement section.

Ideal for foods cooked on multiple shelves.

•

Good for large quantities of baked foods

•

Good results with cookies, biscuits, brownies,

• cupcakes, cream puffs, sweet rolls, angel food cake and bread.

The convection fan circulates the heated air evenly over and around the food.

Convection Roast

To change the oven temperature during probe cooking, touch the BAKE pad and then the number pads to set the new temperature.

Note: If the probe is removed from the food before the ﬁnal temperature is reached, a tone will sound and the display will ﬂash until the probe is removed from the oven. You can use the timer even though you cannot use timed oven operations while using the probe.

Good for large tender cuts of meat, uncovered.

•

The convection fan circulates the heated air evenly over and around the food. Using the grid and broiler pan provided, heated air will be circulated over and around the food being roasted. The heated air seals in juices quickly for a moist and tender product while, at the same time, creating a rich golden brown exterior.

When you are convection roasting it is important that you use the broiler pan and grid for best convection roasting results. The pan is used to catch grease spills and the grid is used to prevent grease spatters.

Place the shelf in the second shelf position from

• the bottom.

Place the grid on the broiler pan.

•

Auto Recipe ™ Conversion

You can use your favorite recipes in the convection oven.

When using CONVECTION BAKE, the oven will automatically convert the oven temperature from regular baking to Convection Bake temperatures.

– 12 –

Using the number pads, enter the temperature recommended in the recipe.

Touch the START pad. The display will show the temperature you entered from your recipe. The

(Continued next page)

oven will automatically convert it to the convection cooking temperature.

Touch the CLEAR/OFF pad when baking is

3. ﬁnished.

To Set the Oven for Convection Baking or Roasting

Touch the CONVECTION BAKE or CONVECTION

1. ROAST pad.

Note: Use pan size recommended in the recipe Some package instructions for frozen casseroles, main dishes or baked goods have been developed using commercial convection ovens. For best results in this oven, preheat the oven and use the temperature, for regular baking, on the package.

Cookware for Convection Cooking

Before using your convection oven, check to see if your cookware leaves room for air circulation in the oven. If you are baking with several pans, leave space between them. Also, be sure the pans do not touch each other or the walls of the oven.

Paper and Plastic: Heat-resistant paper and plastic containers that are recommended for use in regular ovens can be used in convection ovens. Plastic cookware that is heat-resistant to temperatures of 400°F (204°C) can also be used, when oven is below 400°F (204°C).

Metal and Glass: Any type of cookware will work in your convection oven. However, metal pans heat the fastest and are recommended for convection baking.

Darkened or matte-ﬁnished pans will bake faster

• than shiny pans.

Glass or ceramic pans cook more slowly.

•

Touch the number pads to set the desired oven

2. temperature.

Touch the START pad.

To change the oven temperature, touch the CONVECTION BAKE or CONVECTION ROAST pad and then the number pads to set the new temperature.

When the oven starts to heat the changing temperature, starting at 100°F, will be displayed. When the oven reaches the temperature you set, 3 beeps will sound.

4. Touch the CLEAR/OFF pad when ﬁnished.

Note: You will hear a fan while cooking with convection. The fan will stop when the door is opened but the heat will not turn off. The fan will not start until the preheat temperature is reached.

Multi-Shelf Baking

Because heated air is circulated evenly throughout the oven, foods can be baked with excellent results using multiple shelves.

Multi-shelf baking may increase cook times slightly for some foods but the overall result is time saved.

1. are lit on the display and “Set” begins to blink.

On the number pad, press 1 for Low, 2 for

2. Medium or 3 for High. The display “1” changes corresponding to the number pad selected.

Number Pad Setting

1 Lo (pies)

2 Med (casseroles)

3 Hi (meats)

Notes: The warming drawer cannot be used during a self-clean cycle.

The warming drawer has three settings: 1, 2 and

•

3. These settings maintain different temperature levels in the warming drawer.

On some models, if using the oven at the same

• time as the warming drawer, only the oven settings will be displayed.

When Using the Warming Drawer

Always start with hot food. Do not use to heat cold food other than crisping crackers, chips or dry cereal.

Before a Clean Cycle

For the ﬁrst self-clean cycle, we recommend venting your kitchen with an open window or using a ventilation fan or hood.

Remove the broiler pan, broiler grid, all cookware, probe and any aluminum foil from the oven—they cannot withstand the high cleaning temperatures.

Note: If your oven is equipped with nickel oven shelves, remove them before you begin the self-clean cycle.

Soil on the front frame of the range and outside the gasket on the door will need to be cleaned by hand. Clean these areas with hot water, soap-ﬁlled scouring pads or cleansers such as Soft Scrub®. Rinse well with clean water and dry.

Do not clean the gasket. The ﬁberglass material of the oven door gasket cannot withstand abrasion. It is essential for the gasket to remain intact. If you notice it becoming worn or frayed, replace it.

Wipe up any heavy spill overs on the oven bottom. Make sure the oven light bulb cover is in place and the oven light is off.

IMPORTANT: The health of some birds is extremely sensitive to the fumes given off during the selfcleaning cycle of any range. Move birds to another well ventilated room.

Note: Use caution when opening the oven after the self-clean cycle has ended. The oven may still be hot.

How to Set the Oven For Cleaning

Touch the SELF CLEAN pad.

Do not line the warming drawer or pan with aluminum foil. Foil is an excellent heat insulator and will trap heat beneath it. This will upset the performance of the drawer and could damage the interior ﬁnish.

Allow approximately 25 minutes for the warming drawer to preheat.

Do not put liquid or water in the warming drawer.

•

For moist foods, cover them with a lid or aluminum

• foil.

For crisp foods, leave them uncovered.

•

Food should be kept hot in its cooking container or

• transferred to a heat-safe serving dish.

Remove serving spoons, etc., before placing

• containers in warming drawer.

Using the number pads, enter the desired clean

2. time, if a time other than 4 hours 20 minutes is needed. (Clean cycle time is normally 4 hours 20 minutes. You can change the clean time to any time between 3 hours and 5 hours, depending on how dirty your oven is.)

Touch the START pad.

The door locks automatically. The display will show the clean time remaining. It will not be possible to open the oven door until the temperature drops below the lock temperature and the LOCKED light goes off.

The oven shuts off automatically when the clean cycle is complete.

When the LOCKED light is off, the door will be

4. unlocked.

(Continued next page)

– 18 –

The word LOCKED will ﬂash and the oven control

• will signal if you set the clean cycle and forget to close the oven door.

To stop a clean cycle, touch the CLEAR/OFF pad.

• When the LOCKED light goes off, indicating the oven has cooled below the locking temperature, the door can be opened.

After a Clean Cycle

You may notice some white ash in the oven. Wipe it up with a damp cloth after the oven cools.

If white spots remain, remove them with a soapﬁlled scouring pad and rinse thoroughly with a vinegar and water mixture.

The oven door must be closed and all controls set correctly for the cycle to work properly.

How to Delay the Start of Cleaning

Make sure the clock shows the correct time of day.

Touch the SELF CLEAN pad.

Using the number pads, enter the desired clean

2. time.

Touch the DELAY START pad. The earliest start

3. time you can set will appear in the display.

Using the number pads, enter the time of day you

4. want the clean cycle to start.

Touch the START pad.

The door locks automatically. The display will show the start time. It will not be possible to open the oven door until the temperature drops below the lock temperature and the LOCKED light goes off. The oven shuts off automatically when the clean cycle is complete.

When the LOCKED light is off, the door will unlock

6. automatically.

These deposits are usually a salt residue that cannot be removed by the clean cycle.

If the oven is not clean after one clean cycle, repeat the cycle.

You cannot set the oven for cooking until the

• oven is cool enough for the door to unlock.

While the oven is self-cleaning, you can touch

• the CLOCK pad to display the time of day. To return to the clean countdown, touch the COOK TIME pad.

If the shelves become hard to slide, apply a

• small amount of vegetable oil or cooking oil to a paper towel and wipe the edges of the oven shelves with the paper towel.

The word LOCKED will ﬂash and the oven control

• will signal if you set the clean cycle and forget to close the oven door.

To stop a clean cycle, touch the CLEAR/OFF pad.

• When the LOCKED light goes off indicating the oven has cooled below the locking temperature, and open the door.
