Removed the bottom tin work in the oven and removed the burner tube. Tried to remove the igniter bracket but the screws were too tight for the Phillips head and couldn't get vice grips to clamp on the head, so I bent the bracket enough to remove and replace the igniter. Then reassembled.
I give AppliancePros.com a 5 star rating. Site was easy to use, the part was delivered in under 2 days, and it was the correct part packaged carefully so the igniter was protected from breaking.
