Product review (5 stars): Replaces part with 1544679 molded into it
The rubber gasket on my spray arm deteriorated after 5 years. Most parts suppliers want to sell you the entire upper tray assembly. With this part you can replace the spray arm alone. The part has the number 1544679 molded into it. For my dishwasher (Frigidaire Gallery model FGHD2433KF1) this part fits fine.
