I have a Decor SGM364 four burner gas stove top. On the the ignitors does not seem to work. When I turn any of the four knobs, all ignitors spark. One is significantly weaker and it only sparks briefly - not enough to light the gas.
Is that just the round element on the side of the burner needing to be replaced? Do I need to open the cooktop in order to replace it?
Thanks.
