I ordered a new door that was supposed to be shipped with the gasket already installed (part #4344854). When I received the door it didn't have a gasket installed. Evidently Whirlpool doesn't ship the door with the gasket anymore and I need to find out how to install the gasket into the slot of the aluminum frame of the door. There are no hold down clamps around the frame like on some refrigerators that you would loosen and put the flange of the gasket under and then retighten. Instead it only has a slot around the entire door frame. Can you provide instructions on how to get the gasket into the slot correctly without tearing or ruining the gasket?? Thanks :)
