Removed a total of 4 screws, one on each side of the oven wall near front and 2 in a clip at top of oven. After removing screws use a screw driver to slide oven wall out; remove old gasket. Install new gasket. The tricky part was to determine exactly the orientation of the gasket before pushing the oven wall back in place. The narrow part of the gasket must be inserted in the gap between the inner and outer walls. Use a screw driver to help position the gasket as up push the oven wall back in place. Replace all screws and the installation is complete.
