Surface Burner Adjustments
Standard adjustments to the air shutter and gas
metering orifices are not possible on sealed
burners.
If burner flames appear to be abnormal, check the
following:
• Check gas pressure available to the burners.
The required operating pressure is 5" W.C.P.
Natural Gas or 10" W.C.P. L.P. (Propane) Gas.
• Check for drafts entering the burner box from
behind the cooktop.
• Check for blockage or partial blockage of the
orifice. Inspect the orifice to be sure it has
been drilled on center and is free of debris or
burrs.
• Check the burner alignment per Burner
Alignment.
• If the cause of the problem cannot be found,
installing an orifice with smaller diameter
openings may solve the problem. In high
altitude (above 6000 ft.) installation, the
orifices will usually have to be downsized.
Flame Characteristics
Burner flames should be blue and stable with no
yellow tips. (Yellow tipping may be normal for LP
gas.) The flame should not have excessive noise
or lifting of the flame from the burner. If any of
these conditions exist, check the burner ports for
blockage.

BurnerAlignment
Burner alignment is very important for proper
operation. Make sure the locator pin on the burner
ring is properly aligned with the hole on the burner
base. Each brass burner head is marked with a
clock face. Replace the burner head with the
arrow pointing to the rear of the cooktop (12
o’clock position).
Check For Proper Ignition
All the igniters make clicking sounds and spark
even when only a single burner is being turned
on. Do not touch any of the burners when the
igniters are clicking.
1. Push in one control knob and turn 90° to LITE
position.
2. The igniter will spark and the burner will light;
the igniter will cease sparking when the
burner is lit.
3. The first test may require some time while air
is flushed out of the gas line.
4. Turn knob to OFF.
5. Repeat the procedure for each burner.
Sparking
• Input voltage should be 240 VAC and the
ground line should be properly connected to
the range chassis. Voltage should be
measured on one leg of the power supply.
• Make sure electrical circuit is properly
polarized.
• If the igniter electrodes continue to spark after
the burners are lit, check that each burner
component is assembled and seated properly
by observing uniform gaps between each
layer. Disassemble and reassemble as
required.
• If water spills onto the electrode, the burner
will not reignite. The wet electrode will conduct
spark energy to ground, preventing it from
sparking or sensing flame across the spark
gap. The burner will operate normally once the
electrode and wiring connections are dry.
Grates
To repair damaged feet on range cooktop grates,
order the repair kit, part # WB2X11095.
Ignition and Re-ignition
The ignition systems consists of 3 major
components.
• Transformer
• SparkModule
• Electrodes and Associated Wiring
Features of the cooktop determine whether the
ignition system uses a 4 or 5 wire spark module.
The spark modules are rated at 240v and have an
internal transformer. The internal transformer
serves two functions.
• An isolation device to prevent random
sparking in reverse polarity situations.
• To increase the input voltage from 120v to
240v.
During the ignition process all the electrodes will
spark simultaneously when any burner is
selected. Once the ignition process is complete,
the flame ionizes the surrounding air which
completes the sensing circuit and satisfies the
module that a flame is present.

– 13 –
Spark Module
All 36-in. and 48-in. models have a single spark
module located behind the manifold/valve panel.
To remove the module:
1. Remove the manifold/valve panel (see
ComponentAccess).
2. Remove the screws at the upper-right and
lower-left corners of the module.
3. Pull the module up and out.
30-in. Range Models
30-in. range models have a single spark module
located in the center of the burner box.
To remove the module:
1. Remove the burner grates.
2. Lift off the center trim from the burner
maintop.
3. Remove the 2 screws at the front and rear of
the air duct cover, and remove the cover.
4. Remove the 2 screws securing the spark
module to the range.
Spark Module
Grill Burner/Griddle Burner Ignition
Systems (On Some Models)
The grill burner and griddle burner are ignited by
Norton style glowbar ignition systems. The ignition
circuit consists of the grill switch (grill burner
only), griddle thermostat (griddle burner only), the
igniter and the thermal/safety valve (gas valve).
The components are wired in series for each
cooking function.
Note: The igniter resistance decreases as the
igniter surface temperature increases. The safety
valve operates by current, not by voltage.
From a cold start, the igniter needs 30–60
seconds, with voltage applied, to reduce its
electrical resistance enough to provide a
minimum of 3.2 - 3.6 amps of current flow in the
series circuit. This is the required current flow
needed for the safety valve to open and supply
gas to the burner.
The glowbar should provide a steady current flow
of 3.2 to 3.6 amps flowing in the circuit.At that
point, the igniter temperature is between 1800°F
and 2500°F. The igniter will remain energized at all
times during burner operation. If the igniter glows
red but does not draw at least 3.2 - 3.6 amps, the
fault is usually with the igniter, not the valve.

Lock MotorAssembly
The lock motor assembly is located at the center
top of the oven front frame. The assembly
consists of the mounting plate, motor, micro
switches, cam and hook assembly.
To access the assembly:
1. Open the oven door.
2. Remove the 2 Torx screws securing the
mounting plate to the front frame and pull the

Door lock motor operation:
1. When the oven controls are set for CLEAN,
power is applied to the K3 relay coil, which
will energize the lock motor.
2. The lock motor drives the cam that closes
the latch CLOSED switch. As the lock hook
engages, the motor position switch will open,
supplying power to the K1 relay, which turns
the clean timer on.
3. At the end of the clean cycle, when the select
switch is pushed to off or another mode of
operation, the K4 relay will energize the lock
motor to drive the cam to the unlock position.
