RADIANT BURNER TROUBLESHOOTING
Burner does not light, there is a
visible glow on one side of the
Burner� Dome Flame indicator
light on Controller is not lit�
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 you begin to smell gas and the oven is still not
lighting, proceed to step
3.
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�
TURN OFF THE OVEN AT THE CONTROLLER. EXTINGUISH ALL OPEN FLAMES
BEFORE BLEEDING THE GAS LINE.
Remove the plug on the inlet side of the Gas
Valve using a 3/16" hex key wrench� Allow the air to bleed out until you smell gas�
Re-install plug� Allow the gas to dissipate and then turn the oven on� If oven does not
light after 30 seconds, turn it off and back on again, it may still be necessary to do this
a few times�
DO NOT LEAVE THE OVEN UNATTENDED WHILE THE INLET PLUG IS
REMOVED FROM THE GAS VALVE!
4.
Verify that the switch on the Gas Valve is in the ON position� The Valve will power the
Igniter even if the switch is in the OFF position�
5.
Check for loose wire connections at the SV-2 (or SV-3) Gas Valve� Verify that the
MOLEX connectors for the wire harness and Igniter wires are securely plugged into
the Gas Valve� Make sure that the pins are securely locked in to the connector body� If
Burner still does not light, proceed with the following:
6.
Try to determine if the Pilot is actually lighting�
DO NOT CLIMB INTO THE OVEN OR
PLACE FACE OVER BURNER!
It can be difficult to see and can be confused with
the glow from the Igniter, use an inspection mirror if possible� If the Pilot is actually
lighting, make sure Flame Rod is clean and that no debris is interfering with the flame�
Pilot flame should envelope 3/8" to 1/2" of the Flame Rod, and make continuous
contact with the forked ground electrode� If the flame is not making good contact, gas
pressure is low or Pilot orifice is dirty� If flame is overshooting, the Pilot orifice may
be missing, or Pilot may be adjusted too high at the Gas Valve� If Pilot is not lighting
make sure Pilot orifice is not plugged� See the Common Repair Procedures section of
this manual� If flame is good, recheck Igniter wires, make sure pins are seated etc� If
rectification light still does not come on and Burner is not lighting replace Pilot/Igniter�
If after replacing Pilot/Igniter the Burner still does not light, replace the Gas Valve�
