Examined old ice maker. It is held by some Philips screws. There are many screws you don't need to unscrew so look carefully. Then disconnected th dual in line connector. There is a little push tab to squeeze to release. Then the ground is connected with a screw. It's a little hard to see but unscrew that. My replacement came with no instructions or screws so try not to drop the screws down in the netherlands of the fridge. The hardest part was maneuvering the icemaker to reattach the power and ground. Even with that pretty straight forward replacement.
