my question is - do you simply replace igniter or is there a fuse,
sensor or other piece involved.
how is ignitor held in place and should anything else be done upon
removal.

Every one I've seen go bad needed the igniter replaced. Check for cost
locally and at www.repairclinc.com You don't have to go to Sears for it.
Most igniters are made by either Norton or US Carborundum and can be cross
referenced by the dealer.
