Dar S Stansbury Park , UT December 25, 2015 Appliance: Model JBS8895AAC Self taping screws and metal fatigue When removing the burner plates the self-taping screws broke off at the head leaving the majority of the screw frozen in place. Once I was able to see the gas burner orifice holder it was plain to see that the years of heat cycles and moisture had taken a toll on these screws. The Vise-grips and penetrating oils were not able to free up the screw for removal, the next option was to replace the Holder, orifice. Note that there are 4 sizes of this part, double check you are buying the correct part. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
