I have had our original RM2500 out for the initial rebuild a few years ago, the old unit needed the door and frame removed to get it out.
the old RM2500 went out, and I replaced it with the RM2510. You will need to destroy the old mounting flange on your dead RM2400 to get it out, but the replacement RM2410 has slightly narrower mounting flanges, and I was able to get the new fridge in without any door disassembly, just needed to go in slightly diagonally with the mounting flange. (one side in, slide it over, then the other side) It went in fine that way with no removal of the door, screen, or frame.
(the RM2410 and RM2510 are the same width, just taller on the RM2510)
Hope this helps.
