Lynx Igniter Problem

Hi All,

I'm having some problems with my Lynx grill with the old style spark igniters. The grill has three igniters (two for the burners and one for the rotisserie infrared burner. The igniter for one of the regular burners is not working correctly. There is still power going to the igniter, but it will only spark when it is almost touching the steel (?) post adjacent to the burner. I tried cleaning the electrode and steel post but no luck.

Any ideas?

Thanks
