Product review (1 stars): GEE WHIz - What else can GE do to further reduce product quality and durability?
If the back of the knob is as shown in the listing, it is not a direct replacement for the oven knob on a GE Profile model pgb918sem1ss.  The oven knob for this model has a slotted plate held on with two small screws that allows the heat range to be adjusted. The knobs on this expensive convection oven/range are plastic and are not durable.  The foil covers wrinkled after about a year and now the plastic bosses that fit over the gas valve stems  on every knob are cracking from the oven heat. It is possible that one could turn on the gas and not be able to turn it off.  I am not sure what parts to buy as replacements but I hope to find a complete set including the oven knob and 5 burner knobs that are made of metal and will fit correctly.
