This was for a GE Profile Oven that is only 4 years old and this is the second time I had to replace the ignitor glow bar and deflector. I found this deflector part is the replacement for the original deflector which was causing early failure of the ignitor glow bar. There is a GE Service Bulletin RA04-16 that calls out this new deflector. I sure this will be the permanent fix.
Repair is simple. Remove oven door then bottom pan. Replace ignitor glow bar. Replace deflector. Note this part includes directions on how to replace the deflector. Note that you will need to pull oven out to remove 4 screws on a cover that needs to be removed to plug in ignitor glow bar.
