The seal was super easy, no need to disassemble the door. Just push the small pins in and when you get to the ends where you tuck into the door, just take a chopstick or small wooden spoon handle and push in to the two holes, very simple.
The hinges required the door to be removed completely. This is easily done but they can be heavy, our are pretty hefty. Open the door, remove the brackets that cover the top of the hinge, raise the door to the semi open position and lift straight up.
From there, disassemble the door, replace hinges (you do not need directions as everything is self explanatory. Replace hinges and put the door back in the same way you removed it.
Remember, the new hinges have little safety pins so you need to pull those out or the door wont shut completely. But do not remove them until you have the door back in the oven!
