I noticed I never could seem to find them on the part breakdown, so I made a list. Here ya go!
Electrolux and Frigidaire Refrigerator Water Valve Diode in Harnesses by Model and Ice
Refrigerator Style Ice Maker Type Part Number
Side X Side Crescent Cube 5303918287
French Door Finger Evaporator 242102101
French Door Flex Tray 242119101
On French Door models it doesn't matter if there is a crescent cube ice maker in the
freezer section or not, order the diode according to the style of the ice maker that's in
the fresh food section.
