Important Safety Information

Receiving Oven

•Authorized servicer must install the range, in accordance with the Installation Instructions. Adjustments and service should be performed only by authorized servicer.

•Plug range into a 120–volt grounded outlet only. Do not remove round grounding prong from the plug. If in doubt about grounding of the home electrical system, it is consumers responsibility and obligation to have an ungrounded outlet replaced with a properly grounded three-prong outlet in accordance with the National Electrical Code. Do not use an extension cord with this appliance.

•Insure all packing materials are removed from the range before operating it, to prevent fire or smoke damage should the packing material ignite.

•With prolonged use of a range, high floor temperatures could result. Many floor coverings will not be able to withstand this kind of use. Never install range over vinyl tile or linoleum that cannot withstand high temperatures. Never install range directly over carpeting.

Using the Oven

•Do not leave children alone or unattended where a range is hot or in operation. They could be seriously burned.

•Do not allow anyone to climb, stand or hang on the door. They could damage the range and cause severe personal injury.

•Wear proper apparel. Loose fitting or hanging garments should never be worn when using oven. Flammable material could ignite if brought in contact with flame or hot oven surfaces which may cause severe burns.

•Never use range for warming or heating a room. This may cause burns, injuries, or a fire.

•Do not use water on grease fires.

•Do not let grease or other flammable materials collect in or around range.

•Do not repair or replace any part of range unless it is recommended in this manual.

•Use only dry potholders. Moist or damp potholders used on hot surfaces may result in a burn from steam. Do not let a potholder touch the flame. Do not use a towel or a bulky cloth as a potholder.

•Never leave range unattended while cooking. Boilovers can cause smoking and may ignite.

•Only certain types of glass/ceramic, earthenware, or other glazed utensils are suitable for oven use. Unsuitable utensils may break due to sudden temperature change.

•Use care when opening oven door. Let hot air or steam escape before removing or replacing food.

•Do not heat unopened food containers in oven.

Buildup of pressure may cause a container to burst and result in injury.

•Keep range vent ducts unobstructed.

•Place oven racks in desired location while oven is cool. If a rack must be moved while oven is hot, use a dry potholder.

•Do not use aluminum foil to line oven bottom or racks. Aluminum foil can cause a fire and will seriously affect baking results, and damage to porcelain surfaces.

•Do not touch interior surfaces of oven during or immediately after use. Do not let clothing or other flammable materials come in contact with bake or broil burners.

•Other areas of the oven can become hot enough to cause burns, such as vent openings, window, oven door and oven racks.

•To avoid steam burns, do not use a wet sponge or cloth to wipe up spills on hot cooking area.

•Do not store combustible or flammable materials, such as gasoline or other flammable vapors and liquids near or in oven.

•Do not clean oven door gasket located on back of the door. Gasket is necessary to seal the oven and can be damaged as a result of rubbing or being moved.

•Do not drape towels or any materials on oven door handles. These items may ignite causing a fire.

!CAUTION

Do not store items of interest to children in cabinets above range. Children may climb on oven to reach these items and become seriously injured.

Baking, Broiling, and Roasting

•Do not use oven area for storage.

•Stand back from range when opening a hot oven door. Hot air or steam can cause burns to hands, face, and eyes.

•Use only glass cookware appropriate for use in electric ovens.

•Always remove broiler pan from oven when finished broiling. Grease left in pan can catch fire if oven is used without removing grease from the broiler pan.

•Make sure broiler pan is placed correctly to reduce any possibility of grease fires.

•Should a grease fire occur in the broiler pan, turn off oven, and keep oven door closed until fire burns out.

Important Safety Information

Surface Cooking Units

1.Use Proper Pan Size—This appliance is equipped with one or more surface units of different size. Select utensils having flat bottoms large enough to cover the surface unit heating element. The use of undersized utensils will expose a portion of the heating element to direct contact and may result in ignition of clothing. Proper relationship of utensil to burner will also improve efficiency.

2.Never Leave Surface Units Unattended—Boilover causes smoking and greasy spillovers that may ignite.

3.Make Sure Reflector Pans or Drip Bowls Are In Place—Absence of these pans or bowls during cooking may subject wiring or components underneath to damage.

4.Protective Liners—Do not use aluminum foil to line oven bottom. Improper installation of these liners may result in a risk of electrical shock or fire.

5.Glazed Cooking Utensils—Do not use glass, ceramic, earthware, or other glazed utensils. They can damage smoothtop and can break due to sudden change in temperature.

6.Utensil Handles Should be Turned Inward and Not Extend Over Adjacent Surface Units—To reduce the risk of burns, ignition of flammable materials, and spillage due to unintentional contact with the utensil, the handle of a utensil should be positioned so that it is turned inward, and does not extend over adjacent surface units.

7.Do Not Soak Removable Heating Elements—Heating elements should never be immersed in water.

Ovens

1.Use Care When Opening Door—Let hot air or steam escape before removing or replacing food.

2.Do Not Heat Unopened Food Containers—Buildup of pressure may cause container to burst and result in injury.

3.Keep Oven Vent Ducts Unobstructed.

4.Placement of Oven Racks—Always place oven racks in desired location while oven is cool. If rack is removed while oven is hot, do not let potholder contact hot heating element in oven.

In Case of Fire

Fires can occur as a result of over cooking or excessive grease. Though a fire is unlikely, proceed as follows:

Surface Element Fire

1.Smother fire with a nonflammable lid/baking soda, or use a Class ABC or BC extinguisher. Not water, salt or flour.

2.As soon as it is safe to do so, turn the surface controls to “OFF”.

Oven Fires

1.If smoke is visible, do not open oven door.

2.Turn oven control to “OFF”.

3.Turn off power at main circuit breaker or fuse box.

4.Turn on vent to remove smoke.

5.Allow food/grease to burn out in oven.

6.If smoke and fire persist, call fire department.

7.If there is any damage to components, call an authorized servicer before using range.

Precautions

•Do not cook food directly on range top surface, always use cookware.

•Do not mix household cleaning products. Chemical mixtures may interact with hazardous results.

•Do not put plastic items on warm cooking areas.

•Do not slide rough objects across range top surface.

•Do not leave fat heating unless you remain nearby. Fat can ignite if overheated by spilling onto hot surfaces.

•Do not allow pots to boil dry as this can cause damage to cooking surface and pan.

•Do not use range top surface as a cutting board.

“Action Taken” applies as long as the condition exists. If the condition goes away, the control recovers.

If there is a cook function or timer active, the function continues. The user cannot edit the function, and [Cancel] will cancel the cook mode.

Flash rate: 0.2 seconds on, 0.1 second off. Pressing any key will clear the display until the fault clears and is re-triggered. “Action Taken” applies until there is a POR (Power On Reset [“hard reset”]).

If the control believes the door is locked, it will attempt to unlock it when the function cancels and the cavity temperature cools. Special conditions for latch faults (9dxx):

•A known good unlock position is defined as when the unlock switch reads closed and lock switch reads open.

•A known good lock position is defined as when the unlock switch reads open and lock switch reads closed.

•A faulted switch means the switch input is reading an invalid state, neither open nor closed.

•Once a latch fault occurs, latch movement is disabled until there is a POR. An error tone will sound if a function requiring a faulted latch is attempted.

•If at POR, the latch is not at a known good unlock position:

•If the latch is at a good lock position, it will attempt to unlock when the RTD (Resistance Temperature Device) temperature is below 400°F.

•If the latch is not at a good lock position, the control will fault.

•If a latch fault occurs while the RTD is above the lock temperature, the latch will not try to move, but the fault is still logged to EEPROM after the first stage of detection.

•The Display column for latch faults applies 1) If the latch was moving when the fault occurred; 2) If the latch is already in a known locked state when the fault occurs.

•LOCK flashes after a fault is detected and until the unlocked position is achieved. The unlock position may be identified by a successful unlock switch closure, or as the result of timing when the unlock switch is not functioning properly.

•If the last known good position was unlock (e.g. baking, or idle) and a latch fault occurs, the motor is never moved. The fault is logged to EEPROM and is not seen by the user.

•Latch fault detection is in two stages. The first stage is to allow the control to recover without moving the latch. After this:

•If the latch was previously at a known good unlock position, the latch will not move and the control will fault.

•If the control was previously in a known good lock position:

•If the RTD is below 400°F, the latch will attempt to recover to it’s proper position (up to three revolutions). If it cannot, the control will fault and the latch will move to a calculated unlock position.

•If the RTD is at or above 400°F, the control will fault. When the RTD cools to below 400°F, the control will attempt to recover to a good unlock position (up to three revolution). If it cannot, the control will fault and the latch will move to a calculated unlock position.

•Note: If the unlock position cannot be found, this may result in a second fault, the first fault occurring when the latch request was locked, and the second when the latch request is unlocked.

•If the latch is moving when the fault occurs, the control will bypass the first stage of detection and immediately try to find it’s proper position. If it cannot, the control will fault and the latch will move to a calculated unlock position.

•Affected DLBs (Double Line Breaks) and loads are disabled during detection.

•If the control is in a known good unlock position and the lock switch becomes faulted:

•The control will not fault.

•If a function requiring latch movement is attempted while the lock switch is faulted, the control will sound an error tone and the function will be disabled.

•If the control is in a known good lock position and the unlock switch becomes faulted:

•The control will not fault.

•After the function is canceled and unlock is attempted, the control will attempt to unlock the latch according to the procedures in these notes.
