2.Turn all controls to the OFF position.
3.As an added precaution turn off the electricity at the main circuit breaker or fuse box and the gas at the main supply valve.
4.Allow the food or grease to burn itself out in the oven.
If smoke or fire persist call the local fire department.
To avoid risk of property damage or personal injury do not obstruct the flow of combustion or ventilation air to the oven.
To avoid risk of electrical shock, serious personal injury or death: Verify the oven has been properly grounded and always disconnect the electrical supply before servicing this unit.
!WARNING
To avoid risk of electrical shock, property damage, personal injury or death; verify wiring is correct, if components were replaced. Verify proper and complete operation of unit after servicing.
This gas appliance contains or produces a chemical or chemicals which are known to the state of California to cause cancer, birth defects or other reproductive harm. To reduce the risk from substances in the fuel or from fuel combustion make sure this appliance is installed, operated, and maintained according to the instructions in this manual.
NOTE: The maximum gas supply pressure for these models must not exceed 14 inches W.C.P.
Safety Practices for Servicer
Safe and satisfactory operation of gas ranges depends upon its design and proper installation. However, there is one more area of safety to be considered:
Servicing
Listed below are some general precautions and safety practices which should be followed in order to protect the service technician and consumer during service and after service has been completed.
1.Gas smell—Extinguish any and all open flames and open windows.
2.Turn gas off—Service range with gas turned off unless testing requires it.
3.Checking for gas leaks—Never check for leaks with any kind of open flame. Soap and water solution should be used for this purpose. Apply solution to suspected area and watch for air bubbles which indicates a leak. Correct leaks by tightening fittings, screws, connections, applying approved compound, or installing new parts.

Important Safety Information
4.Using lights—Use a hand flashlight when servicing ranges or checking for gas leaks. Electric switches should not be operated where leaks are suspected. This will avoid creating arcing or sparks which could ignite the gas. If electric lights are already turned on, they should not be turned off.
5.Do not smoke—Never smoke while servicing gas ranges, especially when working on piping that contains or has contained gas.
6.Check range when service is completed—After servicing, make visual checks on electrical connection, and check for gas leaks. Inform consumer of the condition of range before leaving.
7.Adhere to all local regulations and codes when performing service.
Receiving Oven
•Installer needs to show consumer location of the range gas shut-off valve and how to shut it off.
•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.
•Ensure range is correctly adjusted by a qualified service technician or installer for the type of gas (Natural or LP). Some ranges can be converted for use with Natural or LP gas.
•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.

Important Safety Information
Baking, Broiling, and Roasting
•Do not use oven area for storage.
•Stand back from range when opening door of a hot oven. Hot air or steam can cause burns to hands, face, and eyes.
•Do not use aluminum foil anywhere in the oven. This could result in a fire hazard and damage the range.
•Use only glass cookware appropriate for use in gas 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.
•Meat that is close to the flame may ignite when broiling. Trim any excess fat to help prevent excessive flare-ups.
•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.

Universal orifices are used on most valves. They must be adjusted or set for the type of gas being used Natural or
LP.
After servicing a valve or orifice verify it is adjusted properly before completing service.
Oven valve is designed to be a safety valve. Two basic designs are used in gas ranges.
Hydraulic type valve Electric type valve
Both types are safety valves because they are indirectly operated or controlled by the oven thermostat, which controls a pilot flame or electric ignitor, to open and close the oven valve.
Ground prong on power cord is connected to the frame, usually a green lead fastened by a screw. In addition, any part or component capable of conducting an electric current is grounded by its mounting.
If any ground wire, screw, strap, nut, etc. is removed for service, or any reason, it must be reconnected to its original position with original fastener before the appliance is put into operation again.
Failure to do so can create a possible shock hazard.

General Information
Specifications
Refer to individual Technical Sheet for specification information.
Placement of the Oven
This freestanding range must be placed in the kitchen or comparable room. All safety guidelines must be followed and free air flow around the range is essential (see Chapter 2).
Do Not Block Air Vents
All air vents must be kept clear during cooking. If air vents are covered during operation, the oven may overheat. If this occurs, a sensitive, thermal safety device automatically removes power to the oven, rendering the oven inoperable. The oven will remain in this state until it has sufficiently cooled.
Location of Model Number
To request service information or replacement parts, the service center will require the complete model, serial, and manufacturing number of your freestanding range. The number can be found on a metal tag located on the back of the control panel. Reach behind the top left corner of the control panel and rotate the tags up to view the data.

General Information
Grounding
NOTE: This appliance must be properly grounded, for personal safety.
Power cord on this appliance is equipped with a threeprong grounding plug. This matches standard three-prong grounding wall receptacle to prevent possibility of electric shock from this appliance.
Consumer should have wall receptacle and circuit checked by qualified electrician to verify receptacle is properly grounded.
It is the consumers responsibility to replace standard twoprong wall receptacles with properly grounded three-prong wall receptacles.
DO NOT, UNDER ANY CIRCUMSTANCES, CUT OR REMOVE THE THIRD (GROUND) PRONG FROM POWER CORD.
For 15 amp circuits only, do not use an adapter on 20 amp circuit. Where local codes permit, a TEMPORARY CONNECTION may be made to a properly grounded twoprong wall receptacle by the use of a UL listed adapter (available at most hardware stores).
Larger slot on adapter must be aligned with larger slot in the wall receptacle to provide proper polarity.
!WARNING
Attaching adapter ground terminal to wall receptacle cover screw does not ground appliance unless the cover screw is metal and not insulated, and wall receptacle is grounded through the house wiring. Consumer should have circuit checked by a qualified electrician to verify receptacle is properly grounded.
When disconnecting power cord from adapter, always hold adapter with one hand. If this is not done, adapter ground terminal is very likely to break with repeated use. Should this happen, DO NOT USE appliance until a proper ground has been established.
Neutral Wire
Ground Hot Line
NOTE: Circuit tester can be used to verify voltage at outlet. Connect one lead to hot line and the other lead to ground. Circuit tester should light.

"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, 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.
•If at POR, the latch is not at a known good 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.
