10. Do not store flammable materials on or near the range. They could explode or burn.

WARNING

To reduce the risk of fire, electrical shock, injury to persons, or damage when using the range, follow these basic precautions:

11. Do not use water on grease fires. Never pick up a flaming pan. Smother flaming pan on range by covering with a wellfitting lid, cookie sheet or flat tray. Flaming grease outside of pan can be extinguished with baking soda, or if available, a multipurpose dry chemical or foam-type extinguisher.

12. Use only dry potholders. Moist or damp potholders on surface elements may result in burns from steam. Do not let the potholder touch a surface element. Do not use a towel or bulky cloth for a potholder. It could catch on fire.

13. Make sure the utensils you use are large enough to contain food and avoid boilovers and spillovers. Heavy splattering or spillovers left on a range can ignite and burn you. Pan size is especially important in deep fat frying.

14. Never leave elements unattended at high heat settings. A boilover could result and cause smoking and greasy spillovers that may ignite.

15. Grease is flammable and should be handled carefully. Let fat cool before attempting to handle it. Do not allow grease to collect around range or in vents. Wipe spillovers immediately.

16. Check to be sure glass cooking utensils are safe for use on the range. Only certain types of glass, glass-ceramic, earthenware or other glazed utensils are suitable for ranges. Other types may break due to the sudden change in temperature.

- v -

17. Turn pan handles inward, but not over other surface elements. This will help reduce the chance of burns, igniting of flammable materials, and spills due to bumping the pan.

18. Do not heat unopened containers. They could explode. The hot contents could cause burns and container particles could cause injury.

19. Do not use decorative covers or trivets over the surface elements.

20. Do not store things children might want above the range. Children could be burned or injured while climbing on range.

21. Do not touch hot surface elements or areas near elements. Areas near surface elements become hot enough to cause burns. During use, do not touch or let clothing or other flammable materials contact surface elements or areas near elements.

22. Do not block the ventilation.

23. Make sure that the elements are turned off when you are finished cooking , and when you are not watching.

24. Be sure all range parts are cool before cleaning.

THE BAKE FUNCTION

Refer to the illustrations on the next page.

When the unit is plugged in and line voltage is applied to the electronic oven control, the following keyboard actions are used to set the

BAKE function:

As electrical current flows through the BAKE element, it heats up. The temperature in the oven is regulated by the temperature sensor.

If the temperature at the back of the oven exceeds 360˚F, the thermal fuse will open, and terminate the BAKE function.

• The clock is set to the time-of-day.

• The BAKE keypad is selected.

• The BAKE temperature is selected.

When the preceding events occur, the BAKE relay energizes, and its contacts close. This provides an electrical circuit through the BAKE element and the thermal fuse to the neutral side of the line*.

The BROIL relay will also close to provide top heat during the BAKE cycle. The BROIL relay will cycle on approximately 20% of the bake operation time.

To preheat the oven before a BAKE cycle, the

BAKE relay is closed for 100% of the preheat time, and the BROIL relay closes for approximately 40% of the preheat time.

THE CLEAN FUNCTION


When the unit is plugged in and line voltage is applied to the electronic oven control, the following keyboard actions are used to set the oven CLEAN function:

• The CLEAN function is selected.

• The desired cleaning time is selected

(if other than 3:30 hrs.).

When the preceding events occur, the BAKE relay energizes, and its contacts close. This provides an electrical circuit through the BAKE element and the thermal fuse to the neutral side of the line.

Temperatures inside the oven will reach 875˚F to 900˚F during the CLEAN cycle. If the temperature at the back of the oven reaches 363˚F, the thermal fuse will open, and the CLEAN cycle will be terminated.

Because the oven reaches extremely hot temperatures, the oven door is latched during the

CLEAN cycle, and remains latched until the oven has cooled to a safe temperature.

The door latching operation occurs when the

LATCH SOLENOID relay closes, and electrical current flows through the LATCH SOLE-

NOID.

After the CLEAN cycle has been completed, the door latch will release when the oven temperature drops below 400˚F.

The BROIL relay also closes to provide a heat circuit. To control the heat build-up at the beginning of the CLEAN cycle, the BAKE relay closes for 60% of the preheat time, and the

BROIL relay closes for 40% of the time until the oven temperature reaches 550˚F. To provide the increased self-clean temperatures after the preheat time has concluded, the relay will cycle as follows:

Bake = 60%

Broil = 70%

COMPONENT DESCRIPTION & TESTING

TROUBLESHOOTING

DOOR LATCH ASSEMBLY

Test Procedure

WARNING




Description

The purpose of the door latch is to lock the oven door during the self-clean cycle. The door latch assembly consists of a solenoid and a switch.

The latch assembly prevents the oven door from being opened during the self-clean cycle, when the oven temperature is above 600˚F.

TERMINALS

SOLENOID

The door latch solenoid operates on a 120-volt dc pulse from the oven control. When the door is in the unlocked position, the solenoid plunger is extended. When the latch sensing switch is open, the control senses that the door is unlocked. When the latch sensing switch closes, the oven control senses that the door is locked.

The latch sensing switch, mounted on the solenoid bracket, is in the N.O. (normallyopen) position. During the self-clean cycle, the oven control sends a 120-volt dc pulse to the solenoid windings, which pulls the plunger in, and moves the latch actuator rod to lock the oven door. The movement of the rod also activates the latch sensing switch and closes it. When the self-clean cycle is over, and the oven temperature reaches approximately 600˚, the oven control sends a 120-volt dc pulse to the solenoid, the plunger is pushed out, the latch actuator rod releases the door and unlocks it, and the sensing switch opens. There are no adjustments for the latch.

To test the solenoid windings, perform the following steps:

1.

Use an ohmmeter and set the range switch to R x 1.

2.

With no power applied, remove the wire from either solenoid terminal.

3.

Touch the leads of the ohmmeter to the terminals of the solenoid. You should obtain a reading of between 45

Ω and 65 Ω.

If the reading is not within the range shown, the solenoid is defective and should be replaced.

OVEN LIGHT

Test Procedure

WARNING




If the oven light does not work:

1.

Remove the oven light bulb and test it for continuity. If the meter reads infinity, the bulb is defective. If the meter shows continuity, reinstall the light bulb, and go to the next step.

2.

Disconnect power from the range, and check the automatic oven light switch (and the manual light switch, if one is installed) for continuity with the switch contacts closed. Also make sure that none of the wire terminals are loose or shorted to the chassis.

3.

Reconnect power to the range and touch the AC voltmeter leads to one of the light switch terminals and the neutral side of the line. If the meter reads zero, the wire from the terminal block of the switch is open. If the meter reads 120-volts AC, go to the next step.

4.

Turn the light switch on and touch the AC voltmeter leads to the other light switch terminal and the neutral side of the line. If the meter reads zero, the switch is open.

If the meter reads 120-volts AC, go to the next step.

5.

Disconnect power to the range, and remove the rear panel.

6.

Reconnect power to the ranage and touch the AC voltmeter leads to the red lead at the light socket terminals and neutral side of the line. If the meter reads zero, the wire from the light switch to the socket is open. If the meter reads 120-volts AC, go to the next step.

7.

Touch the AC voltmeter leads to the white lead at the light socket terminals and neutral side of the line. If the meter reads zero, the socket is defective. If the meter reads 120-volts AC, the neutral line is open.

Description

The operation of the Bake, Broil, and Self-

Clean cycles is controlled by the oven control and the oven temperature sensor. The oven temperature sensor is a “Resistance Temperature Detector” (RTD), and is composed of a stainless steel tube with a thin film of platinum at the end. It is located at the upper left rear corner of the oven cavity. The RTD is a nonadjustable assembly, but may be checked at room temperature, or at 350˚F. A sensor resistance of less than 550 ohms is regarded as a shorted sensor, and a resistance greater than 3000 ohms is regarded as an open sensor. When the oven control senses a resistance of less than 550 ohms, and greater than

3000 ohms, the bake and broil functions will be turned off.

Likely Cause Corrective Action

EEPROM communications.

EEPROM checksum failure.

UL A/D error(s).

1. Use the CANCEL/OFF keypad and verify the failure (if not displayed).

2. Disconnect the power for at least 30-seconds and recheck.

Shorted keypad.

Keypad cable unplugged.

Oven sensor opened.

Oven sensor shorted.

Bake range overtemp.

Clean range overtemp.

Door & latch switches do not agree.

Solenoid not operating or latch switch failure.

Latch during clean error.

1. Use the CANCEL/OFF keypad and verify the failure (if not displayed).

2. Disconnect the power for at least 30-seconds and recheck.

3. Make sure that keypad cable is plugged in and seated in connector on back of control.

4. Reapply power and observe for a minimum of 1-minute.

5. If failure remains, replace the control.

1. Measure the sensor value between the connector pins.

You should measure between 1000

Ω @32˚F and 2697Ω

@ 900˚F. If the measurement does not correlate to real temperature, replace the sensor, and reference steps 3 through 5.

Also measure from the sensor connector to the sensor casing for a possible short.

2. Trace the wires and connectors to the sensor from the control, then from the sensor back to the control.If all connections are okay and there is no wire damage, reference step 3 through 5.

3. Disconnect the power for at least 30-seconds.

4. Reapply power and observe for a minimum of 1-minute.

5. If failure remains, replace the control, and then repeat step 4.

1. If the door is latched: a) Disconnect power and check wires and connectors from the control to the door switch, then from the door switch to the control. If okay, proceed to step b).

b) Replace the door switch.

c) Reapply power and observe for a minimum of 1minute.

2. If the door is not latched: a) Disconnect power and check wires and connectors from the control to the latch switch, then from the latch switch to the control. If okay, proceed to step b).

b) Repeat step a) for the door switch.

3. Measure the door switch. The door open = switch open small low voltage terminals.

4. Measure the latch switch. Unlatch = switch open. CAU-

TION: The oven light contacts are closed.

5. If corrections are made, reconnect the control and varify the operation.

6. If the failure remains, replace the control.
