LG gas range cooktop burners not igniting

Several cook top burners on our 5 year old LG gas range LSG5513ST are no longer igniting (only 1 burner is still igniting) When we try igniting them, we do hear the clicking on ALL of the burners but there is no spark visible on the burners that are not igniting We DO smell gas when attempting to ignite ALL the burners so gas supply does not seem to be the issue The cap and orifice have had a good clean as recommended in this troubleshooting guide by LG (and the other recommendations noted in the troubleshooting guide have been followed as well)- https://www.lg.com/us/support/help-...gas-cooktops-ranges-CT00000303-20150483130772 If one burner is igniting but the rest are just clicking with no spark, is it the spark module or the igniter (or the spark igniter connections) that is likely causing the issue? Any guidance on what to try would be appreciated
