Troubleshooting Oven Pilot
Oven pilot does not work.
Does the pilot light?
No Yes
Check that the oven pilot adjustment on the manifold is open.
Continue to hold the red 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: Remove the
thermocouple from the safety valve. Install a thermocouple adapter
between the safety valve and the thermocouple to measure the
direct-current millivoltage produced by the thermocouple. While
holding the red button, light the pilot and measure the voltage
produced by the thermocouple. If the voltage does not rise above
10 millivolts, adjust the pilot valve and retest. If the voltage still does
not quickly rise above 10 millivolts, replace the thermocouple.
If instead the thermocouple is working properly, replace the safety
valve.
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 red
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.
