Not too bad……front panel off . sides off . Unhook plastic white door spring clips from hinges . 2 screws out from either side of door where the hinges are and this frees up the door . Hold door in position and pull hinges down. Unclip seal from base pan front edge and pull out seal. Its worth looking at and making a note , mental or physical , of how the old door seal sits at the hinge points .The plastic end collars must fit between the hinge and the door inner. IIRC , the new seal comes with a reminder of this .
