I have replaced the ignitor on my Jenn-Air down draft cooktop. The ignitor clicks very slowly and only ignites the gas after there is a buildup of gas.

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.

One burner doesn't consistently light. Igniter sparks but not the same as the other - "good" burners spark at top of igniter and moves around to light, "bad" burner sparks toward the bottom and doesn't move much. I can use the burner by lighting with a match and it works fine. Have tried cleaning with a toothbrush without much success
