SECTION 1. GENERAL INFORMATION

Bake: There will be two separate bake keys,

one for each oven. When the upper oven is chosen there will be a rapid preheat activated which turns both elements on. If the lower oven is selected the elements will cycle at the normal rate. The normal rates for the bake functions in both ovens are: 6 seconds for the broil element, followed by 54 seconds for the bake element.

Broil: There will be two separate broil keys, one for each oven. The HI broil function controls the broil element at 100%, the LO broil is controlled at 80% on time of a 60 second duty cycle. HI broil will be maintained to reach a maximum temperature of 550ºF, LO boil will be maintained at a maximum of 450ºF.

Toasting: Available in upper oven only. Toasting has a maximum allowable time of 10 minutes and maximum temperature of 550ºF. Toasting is only available when the lower oven is not in use. If chosen during lower oven operation the display will scroll an information message regarding use.

Keep Warm: The keep warm function controls only the bake element and is available in the upper oven only. Allowable temperature range is 145 to 190ºF.

Clean: Only one oven is permitted to be cleaned at a time. Both ovens will lock during clean cycle. The clean cycle controls both the broil and the bake element, the broil element is on 100% for the first 40 minutes of the cycle followed by the bake element on 100% for the duration of the cycle. The bake element is cycled once the clean temperature of 865º is reached.

Motorized Door Lock: A 3 RPM motor is used on the door lock assemblies, with each assembly having a locked and unlocked switch. The motor will only run when a clean cycle is chosen and the door actuated switch is in the closed position.

1. Disconnect unit from power source

2. Remove main top by removing screws securing top to burner box and lay aside securely.

3. Visually check the element for evidence of damage or shorting. Then check the element for continuity with an ohmmeter connected to the element terminals. With ohmmeter set at RX1, resistance will normally be below 28 ohms, large and 48 ohms, small. If the element shows no continuity or extremely high resistance, it should be replaced.

4. With power to the unit disconnected, set the control switch for this element on the high setting. With a voltmeter set on 250 or 300 volt scale, re-apply power and check for voltage at the surface element terminal block, then check the surface element.

Each heating element is equipped with a temperature limiter which prevents heat surges and ensures that the heating elements will not overheat.

DUEL ELEMENT

The cooking surface is equipped with a dual element located in the right front position. To operate, push in on the controlknob and turn to the left to control the large element, or push in and turn to the right to control the small element.

ELECTRICAL CONNECTIONS/VOL T AGE

Range Amperage:

The total range wattage is stamped on model plate in kilowatts, (kilowatt = 1,000 watts) to determine amperage for fuse or circuit breaker:

• Check incoming voltage at range main terminal block (pigtail) see illustration.

With range connected to electricity by means of an approved range connector (pigtail) voltmeter reading between L1 and L2 should be approximately 240 VAC. Voltmeter reading between terminal NEUTRAL and terminal LINE 1 should be approximately 120 VAC. Voltmeter reading between NEUTRAL and LINE 2 should be approximately 120 VAC. Center terminal of main terminal block is netural. Range frame is connected to neutral at this point by a ground strap and screw.

• Divide voltage into total wattage. Example: 10. K.W. (stamped on model

plate) X 1,000 = 10,000 watts. Voltage (at terminal block) is 240 VAC. 10,000 ÷ 240 = 41.6 (AMPS). This indicates a fuse or circuit breaker with a rating of slightly over 41 AMPS would be needed.

The range is connected to an outlet through an approved range connector (pigtail) fastened securely to the terminal block with proper strain relief at the range and a three or four pronged plug at the opposite end.

NOTE: For cord (pigtail) replacement, only a power supply cord kit rated at 240 volts minimum, 40 amperes, with closed loop terminals and marked for use with ranges shall be used.

REMEMBER: MOBILE HOMES AND SOME LOCAL CODES DO NOT PERMIT GROUNDING THROUGH NEUTRAL.

HENCE, 4-WIRE SERVICE MUST BE PROVIDED FOR SUCH INSTALLATIONS. ALL OTHERS PERMIT 3-WIRE SER VICE, USE COPPER WIRE ONL Y. AFTER INSTALLATION, ENSURE TIGHTNESS OF ALL ELECTRICAL CONNECTIONS AND REPLACE ALL COVERS.

FAUL T CODES

Fault Codes, Displayed in Upper Time Digits: There are three major fault codes that will be displayed in the time digits of the upper clock display to the left of the colon. Minor fault codes are displayed in the time digits to the right of the display colon, these are used to direct the technician to more specific locations for diagnosis. Major fault codes are as follows:

F1: Temperature runaway. Membrane switch shorted. Alarm is continuous, if cancel key is pressed alarm will stop, if fault still present alarm will repeat. If membrane switch is disconnected the alarm will only sound for 30 seconds and stop. Correction: Test membrane switch and oven sensor, if OK, replace control.

F3: Open or shorted sensor. The cancel key resets the control and stops the alarm. If fault is still present it will reactivate the alarm when a cook mode is chosen. Correction: Check sensor and wiring for shorted or open circuit.

Oven Temperature Adjust: Bake temperature can be adjusted by pressing Bake in either upper or lower oven, entering a temperature of 550ºF, then hold bake key for 3 seconds. Auto set is used to adjust the temperature either + / - 35ºF in 5º F increments (+ / - 21ºC, in 3ºC increments).

Control Lockout: The control can be Locked Out by pressing Setup and then 4. When locked "Control Locked" will be displayed and scroll twice. Press Auto Set to toggle between Locked and Unlocked. The control locktout will not lock out the timer, clock, setup options or oven light.

5. Pitting or flaking.

• Sugary boilovers that were not removed promptly.

• Check the oven temperature selected. Make sure oven is preheated when recipe or directions recommended preheat.

• Check rack positions.

• Use correct pan. Dark pans produce dark browning. Shiny pans produce light browning. See "Cooking Made Simple" booklet for more information on bakeware.

• Check the use of foil in the oven. Never use foil to cover an entire oven rack. Place a small piece of foil on the rack below the pan to catch spillovers.

• Check pan placement. Stagger pans when using two racks. Allow 1-2 inches between pan and oven walls.

• Make sure the oven vent has not been blocked.

• Check to make sure range is level.

• Temperatures often vary between a new oven and an old one. As ovens age, the oven temperature often "drifts" and may become hotter or cooler.

NOTE: It is not recommended to adjust the temperature if only one or two recipes are in question.
