Had to remove built-in oven from wall because the fuse can only be gotten to from the rear.The wire to one side of the fuse was burnt, probably caused from a loose connection. The heat from the loose connection caused the fuse to open. Installed new spade connecters and installed the new fuse. There is a plate on the back of the oven that has to be removed to get to the fuse. It is a Whirlpool. A very poor design.
