Ice maker stop making ice

I pulled out the old one, unscrewed 3 screws un hooked the power cord harness and removed the wire control arm to use in the new ice maker.

I replaced it with the new ice maker, also had to dethaw the water inlet, you can twist it a quarter turn on the back of the frig and pull it out to work on it. Be sure to turn of the water before working on it.
Works great easy job.
