Mod. CCG2420B, burners ignite , work well at all settings with exception of front burner continuously sparking and then intermittent periods of quiet.

SOURCE: Ignitors continue to ignite on other burners

the igniter switch are stuck /need clean contactor of the igniter .

SOURCE: Igniter will not turn off once burners are lit.

The knob swtch is the problem /long time of use that gas stove / the small particles inside the knob are being form a conductor to line that line that hat being ignited once you ignite conductance will flow current to bypass switch /"need to clean knob switch."

Just had this problem today on our seven or eight year old Jenn-Air cooktop. When using the front right burner all ignitors would continue to fire until I turned off the burner. The three other burners worked correctly. After trying all the obvious soulutions w/o success I pulled off that burners control knob and the rubber seal which exposed the valve. Their was a bunch of crud in there. I put a small (one inch) paint brush in there and vigorusly loosened all the crud. I then inserted the nozzle of our central vac - which just happened to fit perfectly - and sucked all the stuff out. I repeated the proceedure a couple more times, reassembled the knob and started the burner. Worked just perfectly!!! YMMV. Good luck.

Hello
Check and make sure that the electric sending units to the side that it's not sparking ( Left side or Right side) are good, you can check that by replacing the one that works with the one that does not. they are located under the knobs on the switch rod, it's very simple, they just sit there with 2 wires, just lift and unplug the wires and replace with the good ones, and if they start clicking when you turn the knobs, then just replace the bad ones with new ones.
Hope this help

Test the ignitor first, if the ignitor does not spark should be the ignitor itself.
