Bryan D Cincinnati , OH December 14, 2018 Appliance: General Electric General Electric JGB870DET2BB Ge Range Jgb870det2bb / : Multiple glow bar igniter failures on me ge gas oven. How to replace Oven Deflector. I noticed that the igniter had burned s hole in the deflector panel above it. I suspected the melted deflector may have been the cause of multiple igniter failures. Replacement of the panel was more difficult than expected because the mounting screw were difficult to remove and even more difficult to screw into the new deflector panel.
