I brought new water valve and ice maker that was in the freezer..To replace water valve. I shut off water to house ,unplugged frig. Removed main supply pipe in back of frig. Took off water valve and removed wire connectors, then hoses. Everything is color coded, so you can not mix anything up it took me 12 minutes to do. Then I replaced freezer parts. Loosen two screws slid it up, unplugged it. Plugged new one in, tighten the two screws. That one took only 5 minutes to install. Push frig back in place and plugged in frig. I heard ice dropping in tray 30 minutes later and all is good
