Product review (5 stars): I replaced white plastic handles with these!
I replaced the standard white plastic handles with these.  With some patience and some small adjustments to the mounting points (screws) on the door face they fit perfectly.  Apparently there have been many updated part numbers for the plastic versions due to continued breakage.  :-o

For full conversion and ease of installation also order two Screw-Shoulder's, Part Number: AP3959968.  These are the appropriate mounting screws for the metal handles to attach to the door face.  They are shapen differently than the plastic handle mount screws.

I own Frigidaire (Electrolux) Model: FFTR1814QW0

Per my success and interwebs research this item should work to replace the following:
Part Number: AP6036330
Part Number: 5304506469 (AP6036330)
Prior P/N's: 5304504507, 5304486359, 5304497105, 242059501, 242059504.
