Electronic Ignition System

Initial lighting and gas flame adjustments

Cooktop and oven burners use electronic igniters in place of standing pilots. When the cooktop control knob is turned to the “LITE” position, the system creates a spark to light the burner. This sparking continues until the control knob is turned to the desired setting.

When the oven control is turned to the desired setting, a hot surface igniter heats to a bright orange and ignites the gas. No sparking occurs. The glow bar remains on while the burner operates.

Check Operation of Cooktop Burners

1.If control panel and knobs were removed earlier, reinstall knobs.

2.Push in and turn each surface unit control knob to “LITE” position. The flame should light within 4 seconds.

3.Turn control knob to “HI” position after burner lights.

4.Check each cooktop burner for proper flame. The small inner once should have a very distinct blue flame ¼" (0.64 cm) to ½" (0.13 cm) long. The outer cone is not as distinct as the inner cone.

5.Turn the control knob quickly to the “LO” position after the burner lights. If the flame goes out, turn the control knob to the “OFF” position.

6.Check each cooktop burner for proper low flame. The low flame should be a minimum, steady blue flame. The flame size should be ¼" to ³⁄₈" (0.64 cm to 0.95 cm) high.

If the low flame needs adjusting:

1.Turn control knob to the “Lo” setting and remove control knob.

2.Insert a small flat-blade screwdriver into the valve stem. Turn the valve adjusting screw to obtain the smallest flame that will not go out when the control of a cold burner is quickly turned from “HI” to “Lo.” Turn right to decrease flame height. Turn left to increase flame height. Repeat for other cooktop burners as needed.

Check Operation of Oven/Broil Burner

Electronic oven control (on some models):

1.Open broiler door.

2.Press the “BAKE” pad.

■The “BAKE” indicator will light.

■“350” will appear in the display.

3.Press the START/ENTER pad.

■The “TEMP” and “ON” indicators will appear.

■The display will show the automatic countdown time

(10 minutes) needed to preheat the oven for selected temperature.

■The oven burner should light in 20-40 seconds; this delay is normal. The oven valve requires a certain time before it will open and allow gas to flow. The oven burner will burn until oven temperature has reached 350°F (177°C). After 20-40 seconds, the oven burner will begin to cycle on and off to maintain the 350°F (177°C) temperature.

Broil burner and oven burner are the same burner. Check the broil function as follows:

1.Press the “BROIL” pad.

■“525” will appear in the display.

■The “BROIL” indicator will light.

2.Press the START/ENTER pad.

■The oven burner should light in 20-40 seconds; this delay is normal. The oven valve requires a certain time before it will open and allow gas to flow.

To avoid damaging the hot surface igniter, do not insert any object into the openings of the shield that surrounds the igniter or clean that area.

3.Check the oven burner for proper flame. The flame should be ½" (0.13 cm) long, with inner cone of bluish-green. The outer mantle should be dark blue and should be clean and soft in character. No yellow tips (not enough air), blowing or lifting (too much air) of flame should occur.
