Jbvorvrnut, I found some felt tape on ebay that worked great with mine. Its cheap and seals it up well. Look in the Masterbuilt XL mods thread and you'll find the link I posted for the felt tape. It was around 5 bucks if I remember right. Some use stove gasket, but this is as cheap a fix as you can get for the door leaks. But door leaks wont cause that much of a temp problem. IMHO, you likely have other issues, like the sticking regulator valve or a stuck float valve inside the LP bottle.
