Item model number 1901A. Part Number 1901A. Model Info 1901A. Manufacturer Whirlpool Parts and Accessories. This is an accessory that can be used with most 50-lb ice makers manufactured in the year 2000 or later; check to see if your model number is compatible.
I have three icemakers. If anything breaks on them it is usually the pump. This is my spare. I had metal trays made at a local sheet metal shop to fit under the ice makers. Three sides of the tray have about a 1 inch lip and the front side does not. The tray is slightly shorter than the depth of the icemaker so it is not visible. Run a small bead of clear urethane under the front edge of the tray and wipe clean. This prevents water from wicking back under the tray. The tray act as a barrier and will force any water leakage out the front for you to see and fix before it ruins something and creates a expensive repair. This pump will shut the icemaker down if it stops working and prevent bigger problems. Don't use the inexpensive ones from the big box stores that do not shut the icemaker down
