GAS BURNER TROUBLESHOOTING
If the green light is OFF:
With the oven ON Check for 24 VAC between TH and
TR terminals on the ICS-2 Module at the rear of the oven� If there is 24 VAC then
the ICS-2 Module is bad�
If there is not 24 VAC present:
Check that Module is wired according to the
schematic on the oven� Check wiring connections in the front Junction Box on the
Transformer Plate and at the terminal strip on the Touchpad Control Board� With
the oven on check for 24 VAC between the brown and white wires at the terminal
strip on the back of the Control Board� If there is no voltage and the Controller is
on, turn OFF the power supplying the oven� Disconnect all wires from the Control
Board terminal strip EXCEPT pink, white and brown� Repower the oven, turn the
control back on� If 24 VAC now present, check remaining wiring� Especially make
sure that Thermocouple wiring is not shorted to ground� If 24 VAC is still not
present-replace the Control Board�
Light on ICS Module is flashing - Module has timed out� Turn the oven OFF,
then back on to reset� If there is no spark at the Burner follow the steps on the
previous page to troubleshoot the problem� If there is spark proceed to the next
step below� Replace the Module if it does not reset�
Symptom
Cause and/or Solution
< Continued from previous page
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�

1.
Gas supply to the oven has been turned OFF� Check manual shutoffs, fire
suppression system resets, etc�
2.
There may be air in the gas line� On a new oven start-up there may be air in
the gas line� Turn the oven ON for about 30 seconds� Turn it back OFF and
then back ON for 30 seconds� Repeat this up to five times� If oven does not
light and you are not smelling gas continue with this step, it will be necessary
to remove the inlet plug on the Gas Valve which will enable the air to be bled
more quickly from the line� This can be done on the IR Gas Valve if equipped�
Remove the plug on the inlet side of the Gas Valve using a hex key wrench�
Allow the air to bleed out until you smell gas� Re-install the plug� Allow the
gas to dissipate and then turn the oven ON� If the oven does not light after
30 seconds, turn it OFF and back ON again� It may be necessary to do this
a few times�
EXTINGUISH ALL OPEN FLAMES BEFORE BLEEDING THE GAS
LINE. DO NOT LEAVE THE OVEN UNATTENDED WHILE THE INLET PLUG IS
REMOVED FROM THE Gas Valve!

Check for loose wire connections at the ICS Module and the Gas Valve�
