Icemaker would not stop putting out water, then would not make ice

First, I unplugged the power to the entire fridge, and then removed the ice tray and ice door. Next, I unplugged the flat plug in the very back left behind the icemaker. Then I removed the 1/4" hex head sheet metal screws (2) and the phillips head screw (1) that hold the icemaker to the left side of the freezer wall. New icemaker came with a different style trip arm, so I used it. Plugged new icemaker in before reattaching it with the same (3) screws. Replaced ice tray and door, plugged in fridge, and waited....Dumped its first batch of ice maybe a couple of hours later. Not much trouble-shooting is needed when the entire icemaker is as easy and relatively inexpensive to replace as this. Twenty minutes, max.
