Before we get our hands dirty, let’s make sure you didn’t accidentally buy a fancy toaster. Open that box and look for the ice maker unit, a water supply line (usually a skinny, braided hose), and a saddle valve or shut-off kit.
If your ice maker came with a manual, give it a quick skim. It’s like reading the rules to a board game—annoying, but it saves you from a meltdown later.
Most importantly, make sure your ice maker is unplugged for now. Electricity and water are great friends—until they’re not.
