John Y Rocklin , CA December 02, 2024 Appliance: Whirlpool Range/Oven, Gas, Double WGG745S0FS02 Whirlpool Range Wgg745s0fs02: Upper oven bake element would not ignite. How to replace Range Wing Nut. I replaced the igniter. It was made more difficult by one of the machine screws on the oven had been over torqued at the factory. It had stripped the screw and made removal of the old igniter very difficult. If not for that, this would have been a 15 minute repair. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
