Grates
To repair damaged feet on range cooktop grates,
order the repair kit, part # WB2X11095.
Burner Alignment
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.
Ignition and Re-ignition
The ignition systems consists of 3 major
components.
•
Transformer
•
Spark Module
•
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.
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.
