Ignition is undependable. Usually, we light the burners with a match. Sometimes, we see sparks next to the igniters and hear clicks and the burners will ignite. One burner continuously "clicks" when in use. Drying off/out the burners does not restore ignition or stop the clicking. Do we need a new spark module or is can failure of the igniter on one burner prevent ignition of the others?

Thank you Dan for your analysis and diagnostic questions. About 95% of the one hears and smells the gas flow, but there is no clicking or sparking. The failure of all the burners to spark most of the time suggests a central malfunction. The 5% of the time when the igniters spark, they light the burners. I'll observe the igniter on the burner the continuously clicks when lit (in synchrony with the sparking igniters on the burners not in use) next time I get a spark.
