SERVICE DATA SHEET 318127026 (0510) Rev. A
Gas Range with Electronic Oven Control
To avoid the possibility of personal injury and/or property damage, it is important that safe servicing practices be
observed. The following are examples of some, but not all, of these practices.
1. Do not attempt a product repair if you have any doubts as to your ability to complete it in a safe and satisfactory
manner.
2. Before servicing or moving an appliance, remove power cord from electric outlet, trip circuit breaker to OFF, or
remove fuse and turn off gas supply.
3. Never interfere with the proper installation of any safety device.
4. USE ONLY REPLACEMENT PARTS CATALOGED FOR THIS APPLIANCE. SUBSTITUTIONS MAY DEFEAT COMPLIANCE
WITH SAFETY STANDARDS SET FOR HOME APPLIANCES.
5. GROUNDING: The standard color coding for safety ground wires is GREEN OR GREEN WITH YELLOW STRIPES.
Ground leads are not to be used as current carrying conductors. IT IS EXTREMELY IMPORTANT THAT THE SERVICE
TECHNICIAN REESTABLISH ALL SAFETY GROUNDS PRIOR TO COMPLETION OF SERVICE. FAILURE TO DO SO
WILL CREATE A POTENTIAL HAZARD.
6. Prior to returning the product to service, ensure that:
• All electric connections are correct and secure.
• All electrical leads are properly dressed and secured away from sharp edges, high-temperature components,
and moving parts.
• All non-insulated electrical terminals, connectors, heaters, etc. are adequately spaced away from all metal
parts and panels.
• All safety grounds (both internal and external) are correctly and securely reassembled.
• All panels are properly and securely reassembled.
SAFE SERVICING PRACTICES
This service data sheet is intended for use by persons having electrical and mechanical training and a level of knowledge
of these subjects generally considered acceptable in the appliance repair trade. The manufacturer cannot be responsible,
nor assume any liability, for injury or damage of any kind arising from the use of this data sheet.

During a cleaning process, the oven uses bake burner.
During a normal bake mode, the controller preheats the oven and bake with the bake burner.

F10 Control has sensed a potential runaway
oven condition. Control may have shorted
relay, RTD sensor probe may have gone
bad.
F11 Shorted keypad.
F13 Control's internal checksum may have
become corrupted.
F14 Misconnected flat cables.
F30 Open RTD sensor probe/ wiring problem.
Note: EOC may initially display an "F1",
thinking a runaway condition exists.
F31 Shorted RTD sensor probe / wiring problem.
Note: "F3" is displayed when oven is in
active mode or an attempt to enter an
active mode is made.
F90 Door motor mechanism failure.

Likely Failure Condition/Cause Suggested Corrective Action
1. Check RTD sensor probe and replace if necessary. If oven is
overheating, disconnect power. If oven continues to overheat
when the power is reapplied, replace EOC. Severe overheating may
require the entire oven to be replaced, should damage be extensive.
2. Press CLEAR key.
3. Disconnect power, wait 30 seconds and reapply power. If fault
returns upon power-up, replace EOC.
4. Disconnect power; verify flat cable connections (P12 or P13).
1. Press CLEAR key.
2. Check wiring in probe circuit for possible open condition. Check
RTD resistance at room temperature (compare to probe resistance
chart). If resistance does not match the chart, replace the RTD
sensor probe.
3. Let the oven cool down and restart the function
1. Press CLEAR key.
2. If CLEAR key does not eliminate problem, turn off power for 30
seconds, then turn on power.
3. Check wiring of Lock Motor, and Lock Switch and Door Switch
circuits.
4. Unplug P5, apply power (L1) directly to the Lock Motor, if the motor
does not rotate, replace Lock Motor Assembly. Plug P5.
5. Check Lock Switch A for proper operation (do they open and close,
check with ohmmeter). The Lock Motor may be powered as in above
step to open and close Lock Switch. If the Lock Switch is defective,
replace Motor Lock Assembly.
6. If all above steps fail to correct situation, replace control.

ELECTRONIC OVEN CONTROL
It is normal to see a temperature overshoot in the
first rise of all modes when you monitor the temperature.
FIRST RISE
OVEN CALIBRATION
Set the electronic oven control for normal baking at 350°F/176°C. Obtain an average oven temperature after a
minimum of 5 cycles. Press Cancel to end bake mode.
Note: Changing calibration affects all the cooking modes but not the clean mode.

GAS COOKTOP REMOVAL
OVEN DOOR REMOVAL AND REPLACEMENT
The door is heavy. For safe, temporary storage, lay the door flat with the
inside of the door facing down. The oven door can be removed to make oven cleaning
easier.
To Remove Oven Door:
1. Open door approximately 4 inches to the stop position.
2. Grasp door at side edges.
3. Lift door up and off hinges.
To Replace Oven Door:
1. Be sure the hinge arms are in the stop position. Be careful if pulling the hinges open by
hand. The hinges may snap back against the oven frame and could pinch fingers.
2. Hold the door at the sides near the top.
3. Slide the door down onto the hinges as far as it will go and close the door.
4. If the door is not in line with the oven frame, remove door and repeat the above steps.
Removing the
Oven Door
1. Shut off gas to range.
2. Disconnect power.
3. Remove gas supply line at the regulator. Move
range out of the cabinet opening.
4. Remove grates, burner covers, knobs and seals.
5. Remove screws securing rings and remove rings.
Inspect burners, loose screws, electrode, cleanliness,
etc.
6. Remove back upper panel.
7. Remove the 2 screws at the back of the cooktop.
8. Remove the 5 knobs.
9. Remove the 2 screws securing the manifold (see
figure).
10. Slide out the cooktop.
11. To reassemble the cooktop, reverse procedure.

DOOR LOCK MECHANISM
The appliance is equipped with an electronic oven control and
has an auto locking door latch feature. When the self clean
cycle is programmed, the door is locked by a motor operated
latch system. The interior of oven does'nt need to heat up to
500°F/260°C before the door locks. However, until the
temperature inside oven reaches 500°F/260°C, the self-clean
program can be canceled and door will unlock immediately.
After oven reaches temperatures
over 500°F/260°C, the door will
not unlock until temperature
drops below 500°F/260°C.
