I’ve just replaced the grill igniter for the second time. Seems unusual in a 7 year old cooktop. In looking at the wiring diagram and reading instructions for the operation of the appliance, it seems to me something else is wrong. The valve to actuate the grill has two positions, "Lite" and the "Hi" to "Low" setting. Instructions say to turn to "Lite" and when it lights up to set the temp desired. There is a perceptible stop between the "Lite" and the temp settings. The wiring diagram indicates a switch between a safety valve and the igniter which would appear to indicate that after lighting the igniter should turn off. It doesn’t regardless of valve setting. The new igniter I just installed is extremely bright and stays on throughout the grilling process. I think that’s what is wasting the igniters, they just burn out. Can anyone confirm the operation and that the igniter should turn off after passing the detent on the valve? Where is the switch located, in the safety valve (which I’ve already had to replace one other time,) in the valve, or elsewhere? Per the diagram it seems independent of the modules for the simmer and burner control and nothing in the diagram and parts list indicates a separate valve.
Hi Bob,
The grill igniter works the same way as the oven igniter and it must stay "on" as long as you need the burner to stay "on".
You can learn how the igniter works from one of previous posts: http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/1897-oven-wont-lite.html

Gene.
P.S The average life time for an igniter is about 3 to 5 years (if used weekly).
the machine is noisy when in spin mode, like squeeling brakes. How do I fix it?
Please describe the noise.
