"SCREW 8-18 X 1/2 "" "

I replaced the oven igniter, discovered the floor of the oven had rusted through, so I replaced that as well. The burner on top of the stove would not light as it was designed, and because the 12 screws that hold the range top and burners in place were rusted in place I ended up buying a new range because removing the screws on the burners proved impossible, even when I tried to drill them out with a lefthanded screw removal tool. I should have just kept lighting the burner that would not light, with a match. That was a repair too far, that forced me to buy a new GE Range and throw this one in the trash. The igniter, oven floor replacement was easy. The burner igniter after 18 years proved impossible. .I installed the 18 yr. old burner grates on the new range, but the drip pans would not fit the new stove. New GE Range instructions were near useless. Do Not trust them, especially the Orifice change details NG to LPG.
