ice maker not working

I replaced this same ice maker a month before, if that long, using a part I found $40 cheaper from another site. Needless to say you get what you pay for, the existing part was not exactly the same as the original and leaked water all over the place. I removed the not so old icemaker by removing the flapper door and removing the harness cover then pulling out the existing icemaker followed by disconnecting the wiring harness. Now with the old icemaker removed I removed the bottom tray/shield from the existing ice maker by removing the three screws from it then attached the tray to the bottom of the new ice maker from PartSelect which did not come with the bottom tray/shield. Finally, I executed the removal process in reverse order to install the new ice maker.
