Replaced oven igniter assembly. GE Profile oven: needed to remove bottom pan to remove the door. Hinges need to be unlocked. Removed drawer to turn off gas and turned off electricity at breaker. 1/4 inch driver used to remove screws. The two screws which held the oven igniter assembly in place broke off at the heads. Drilled out and used two bolts and nuts to reattach assembly. Still a simple job and quick job despite need to drill out frozen screws and make a quick trip to hardware store for bolts and nuts.
