Tl;dr: Watch the repair video FIRST. This will take you less than 15m if you do watch the video. You need to remove a door panel, you can't directly replace the icemaker. Even without doing that, it took me less than 30 minutes. 4 screws, a panel removal, a couple of computer-style power plugs, and you'll have ice again no problem. Stupid easy.
Initially, we did the button reset on the old icemaker, and it didn't beep or anything, so that was enough troubleshooting for me to replace the 9-year-old icemaker that's part of an undoubtedly refurbished low-end Samsung fridge that came to live in my home before I bought it, during the strip-n-flip.
Took about a week, maybe 10 days to get here. I did NOT pay for expedited shipping, a couple bags of ice = $6, which is less than expedited shipping.
Once it arrived, I was almost able to do the entire removal and re-installation myself - it's not complicated. That said, Don't do what I did.
After removing a bunch of screws and still not being able to remove the ice panel from the inside of the freezer, I watched the video and realized 1. I removed too many screws; 2. There's a clip on the door panel you slide a screwdriver into to remove the panel. You can't replace.
The panel and the icemaker come off together if you watched the video and only removed the correct screws. You can close the freezer again now to protect your perishables.
Removing the broken icemaker was the 2 extras screws. I shouldn't have removed when I did. The new one slotted right in and everything lined up perfectly.
Reattaching everything is a MINOR handful, as you kind of need to balance the panel with the new icemaker with your hip as you get the plugs for the water pump and icemaker plugged back in, and then line up the panel to snap it back in place. Not difficult, just don't be drinking your beer at the same exact second - you can set it down for a moment and you're still cool.
Once I drove the 4 screws back in, I pressed the button on the icemaker till I heard it make a beepildy noise. I assume that turned it on and told the freezer that we are back in business.
An hour or so later I heard ice fall into the bin. Hooray!
