– Bad thermopile.
– Bad thermopile connections at safety valve.
– Bad safety valve.
– Clogged orifice.
– Dirty pilot
– Draft condition.
– Improper ventilation system.

Troubleshooting Oven Pilot
T ROUBLESHOOTING
Oven pilot does not work.
Does the pilot light? No Yes
Check that the oven pilot adjustment on the gas valve is open. Continue to hold the button for 30 seconds. The pilot should remain
lit after the button is released. If it does not, wait five minutes and
try again.
If the pilot will not remain lit, do the following: Set a multimeter to
the thermopile connections on the safety valve to test the DC
millivolts of the thermopile. While holding the button, light the pilot
and messure the voltage produced by the thermopile. The voltage
should read abobe 450 millivolts.
If the pilot is not lit, attempt to light the pilot by raising the kick panel
slightly and rotating its top edge outward. Press and hold the button
on the oven safety valve and put a flame to the pilot.
If the pilot still will not light, do the following: Remove the oven
bottom. Loosen the pilot nut on the burner bracket. Remove the
pilot tube from the safety valve. Remove the pilot orifice from the
pilot or end of the tube and check for debris.
Re-install the pilot orifice and tubing.
Check whether the pilot flame is lit by looking through the hole in
the bottom of the oven. Leave the oven door open for five minutes
to allow gas fumes to clear.
If the voltage does not rise above 450 millivolts, then adjust or
clean the pilot assembly to chieve a larger flame. If the voltage
will not adjust properly, then replace the thermopile.
if you continue to have issues after replacing the thermpile, then

Does the pilot light? No Yes
If the voltage of the thermopile is oven 450 millivolts, then remove
the thermostat wires and test the pilot again. If the pilot continues
to fail, then replace the safely Value. If you continue to have
issues after replacing the safety valve, then contact Southbend
Technical Support for assistance at 919-762-1000 option 2.
