Door gasket easy pull off and replace. Hinges on oven door required loosening of natural gas line in my case and pulling Jenn-air out of counter far enough to get to sides of unit. Removed cosmetic side panels and then old hinges. New hinges, only 2 screws through frame and hinge Replace cosmetic side panels, move Jenn-air back into counter an reconnect natural gas line. Note I used Teflon tape designed for natural gas on gas line connection.
