Hot Oven Restart
If you turn off the oven but then decide to turn it back on before it has cooled to room
temperature, the burner may not light properly.
This is due to the thermostat still sensing
a heated oven and not allowing the maximum gas flow rate into the burner.
Press in and
turn the oven control knob counter clockwise all the way to the “BROIL” position to
relight the burner.
After the burner has ignited, you may adjust the oven control to the
desired temperature.
If the oven burner does not ignite and maintain the flame, one of the following situations
may have occurred.
1.
The pilot burner has gone out.
Relight the oven pilot.
2.
The pilot will not keep the flame safety probe heated.
Adjust the size of the pilot
flame.
Or, the thermocouple connection at the thermostat may need to be tightened.
3.
The flame safety probe may not be properly located.
Locate the probe directly
over the pilot burner.
On spark ignition ovens, the end of the flame safety probe
must very close to the side of the burner right in front of the flame ports.
4.
The burner is not in its proper position.
Make sure the rear of the burner is seated
on the injector elbow and the front is bolted onto the burner support.
5.
The spark ignitor is defective.
Contact an authorized service technician.
6.
The glow bar ignitor is defective.
Contact an authorized service technician.
6. Oven Burner Air Shutter Adjustment
The oven burner flame should be a clean, blue flame with distinct inner cones
approximately _” long.
A soft, lazy flame with indistinct cones means too much gas or
not enough air.
A noisy lifting flame means too much air.
If adjustments are necessary
you must first loosen the lock screw located at the top of the air shutter, then rotate the air
shutter to correct setting, and retighten screw.
Oven burner flame can be checked as follows (without burner baffle in place):
•
To correct a yellow flame-Increase size of air shutter opening.
•
To correct a lifting, but distinct, blue flame-Decrease size of air shutter opening.
The air shutter should be set approximately 2/3 open for natural gas, and approximately
full open on LP (Propane) gas.
