Clock Knob - black

First I removed 7 screws, using a Philips head screwdriver, to allow access to the inside of the oven door. I then removed several more screws to separate the panel holding the seal so that I could remove it and replace it with the new seal. Once the seal was in place I re-inserted all the screws to the panel and door to complete the repair. The knobs just slipped on to replace the ones that broke and fell off.
