Product review (1 stars): THIS IS NOT THE SAME AS THE MHY62044106 OEM!!!
THIS DOES NOT WORK THE SAME AS THE MHY62044106 OEM!!!  This is supposed to be the correct part number for my model LFX31925SW. This doesn't work without modification.  When installed as is, the door flap will not lay back flat against the door. It will lay 3/4 of the way and the spring will then bind and keep the flap ajar about 1/2 to 3/4 of an inch. Unless the flap sits completely against the door, you will drag against the opposite door frame, or catch the flap on the channel guide at the top of the door.  If that happens, the flap can be damaged beyond repair.  Dont get me wrong, the spring looks like it will fit. It has the same number of winds, but the leg bends are not correct. They are not bent in the correct spot and the bends are not sharp enough.  The legs are also too long. They will have to be trimmed and rebent. If you are not handy, do not order this.  Find the OEM part for the extra $3. This item is nonreturnable according to amazon.

UPDATE 10/15/2017: The item is nonreturnable, not nonrefundable.  Amazon C.S. took care of it immediately.  Thanks
