GAS BURNER TROUBLESHOOTING
Symptom
Cause and/or Solution
OPERATIONAL OVERVIEW
Wood Stone CE gas ovens utilize a spark to Pilot ignition system�
Flame rectification is sensed through the flame rod on the Pilot/Igniter
to ground via the Pilot Tube� Each Burner has its own ignition (ICS)
Module and Gas Valve� When the ICS Module receives 24 VAC power,
it sends spark to the Igniter and opens the Pilot solenoid on the Gas
Valve� When the Module senses flame rectification at the Pilot it will
then power the main solenoid in the Gas Valve causing the Burner to
fire� If the Pilot goes out, the ICS will automatically attempt to relight
the Pilot� If the green light on the ICS is lit, the Module is receiving
power� A flashing green light means the Module has timed out while
trying to light the Pilot� Turn the oven OFF, then back on, to reset the
Module�
RADIANT FLAME BURNER TROUBLESHOOTING
The Radiant Flame Burner is the Burner located at the rear of the oven� On some models, this Burner is located on the side of the
oven chamber� It is the main heat source for all ovens equipped with this Burner� The flame height is adjustable by means of the
Throttle Control Valve located on the front of the oven on the left side�
Burner does not light, oven Controller is
on, no spark at the Burner�
Note:
On any call where the complaint
is that the Radiant Burner will not light,
stay lit or is going out intermittently,
Wood Stone strongly recommends that
the Radiant Burner be removed for
inspection and cleaning� The majority
of Radiant Burner problems can be
traced to debris in the Burner� See the
“Common Repair Procedures” section of
this manual�
When the oven is on the green light on the ICS-2 Module should be lit� This Module
is located beneath the oven and mounted at the rear�
If the green light is on
(light may start blinking after few minutes): Turn the oven
OFF� Remove the rear Burner and remove any debris on the Burner� (See the
“Common Repairs” section of this manual�) Check the Igniter wire for continuity
between the terminal on the end and the spark electrode on the Igniter� Check the
Igniter for damage (cracked insulator, bent or broken electrode, etc�)� Make sure
electrode is not shorted to ground� Replace Igniter if damaged� Clean the spark
electrode if needed�
If Igniter is fine:
With the oven OFF remove the Igniter wire from the ICS Module�
Turn the oven back on� Keep away from the Igniter terminal on the Module� You
should hear a repetitive clicking sound coming from the Module� If no sound is
heard replace the Module� If the ICS Module is bad check both Solenoid Coils on the
Gas Valve for continuity� Make sure there are no shorts to ground on the valve�
