Electronic Ignition System - Whirlpool WFG770H0FZ Manual

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, as long as the control knob is turned to
"LITE."
When the oven control is turned to the desired setting, sparking
occurs and ignites the gas.
Check Operation of Cooktop Burners
Standard Surface Burners
Push in and turn each control knob to the "LITE" position.
The flame should light within 4 seconds. The first time a burner is
lit, it may take longer than 4 seconds to light because of air in the
gas line.
If Burners Do Not Light Properly:
� Turn cooktop control knob to the "OFF" position.
� Check that the range is plugged in. Check that the circuit
breaker has not tripped or the household fuse has not blown.
� Check that the gas shutoff valves are set to the "open"
position.
� Check that burner caps are properly positioned on burner
bases.
Repeat start-up. If a burner does not light at this point, turn the
control knobs to the "OFF" position and contact your dealer or
authorized service company for assistance.
Power Failure
In case of prolonged power failure, the surface burners can be lit
manually. Hold a lit match near a burner, and turn knob
counterclockwise to LITE. After the burner lights, turn knob to
desired setting.
Adjust Flame Height
Adjust the height of top burner flames. The cooktop "low" burner
flame should be a steady blue flame approximately 1/4" (6.4 mm)
high.
A. Low flame
B. High flame
