The problem:

Front two burners do not ignite. Back three burners ignite perfectly. I have replaced igniters on all, spark switch assembly, burner wires. Problem still persists. Checked two faulty burners to see if they are getting a charge... yes they are but the charge may not be strong enough to reach the grounded metal on top of burner. Gas is flowing fine too.

Should I next consider replacing the Spark Module? Any other suggestions?

Thanks.
