I installed a new ignitor. The only difficulty with the job is removing the various heat baffles to get to the burner itself with the ignitor attached. Also I did some clean-up of the oven which took time. I also tested the new ignitor vs. the old for conductance to make sure I had a faulty part. I have done this repair before and was fairly certain what the problem was. A year or so ago I had replaced the motherboard control so I knew it wasn't that.
