A:Answer Check online for the ice maker part - making sure you have selected the one for your refrigerator model. Also, the original manual might indicate which one. I'd also suggest looking at ice maker reviews, as they are sometimes mixed.
For the water line, you would need to check with a plumber or handyman for costs. An experienced homeowner might be able to install the line themselves. If you are a renter, be careful, as you might want to check with the landlord.
