have replacement glass, but can not get door apart or off the oven 
I’m afraid I am not familiar with that model and the parts diagrams do not help to show how the door on it might be put together. Maybe someone with experience with that model will drop by and offer tips? Often there are 2-3 screws through the door from the inside panel that hold the two halves of the door together.
For how to remove the door from the range see the owner’s manual. Different models use different methods. If you no longer have its owner’s manual, one can be downloaded from the Whirlpool web site.
