One burner, right front (not the Extra Low burners), on our cooktop will not ignite from ignition plug. I replaced AP3842359 (428049) Switch and AP2838563 (189324) Ignition plug assembly, no change. I can light burner with a match, but no spark. Wife says she saw a blue flash before burner became inoperable. Any other parts that could be responsible? Other three burners still working fine.
thanks in advance,
Mark
