Product review (5 stars): Exact Match for Armana ARR624W
The Replacement Whirlpool 77001094 Bake Element part was an exact Match for my Amana ARR624W oven.  It works well.  The dimensions are about 15 1/8 front to back (not including the part which plugs into the back of the oven) and 13 1/4 side to side.  It was easy to install (3 screws).  The shipping was quick.
