Installed a door form Heater Treater. After some hot weather there is a part problem. The adhesive that holds the rubber seals to the doors is failing. Talked with H.T. and they are aware of the problem. Rubber seal comes loose from door and catches in fan motor Assy. and binds door. With the cooler weather and the heat on it also comes loose. If installing any doors I would inspect the seal for possible problems before going thru all the work it takes to change the doors. .
