If you look at the front control panel there you will see the drip tray there.
Lift this up and see if theres 2 screws there.
Let me know what you see.
Yes the door frame is designed to come off.
If theres no screws under the drip tray then the outer frame is clipped into the door panel.
If you look under the frame on the left hand side on some models theres a small hole. Insert a small screwdriver in there and push the tab and you should be able to pull the frame away from the door from there.
The frame is made to be removed from there. You dont need to strip the complete door down to get behind there.
Once you release it from the bottom the rest should pull off easy from there then. Its just starting it off thats tight at first.
