My upright freezer door won't seal or stay closed. It used to "suck closed" after I opened and closed the door, making reopening difficult. Then the drain froze up. I melted the ice from the drain with a hair dryer and some warm water. Ever since I thawed the drain the door will not stay fully closed. When the compressor and inside fan turn on, the door freely swings open about the thickness of a sheet of paper. The door seal lines up perfectly with the freezer doorway. If I don't lean something against the door all the time, my freezer will fill up with snow.

Also, My defrost tray is completely dry and my heating coil is extremely hot. Any assistance would be greatly appreciated.
