My folks used to sell appliances. Back then it was always the ice maker.
We have only had one refrigerator/freezer unit that came with an ice maker. We never hooked it up, no problem.
Currently we have had two Frigidaire refrigerator/freezers for 10+ years. They are units that can be set to be a refrigerator or a freezer. The refrigerator had a problem in the first year under warrantee. The freezer has to be fussed with if someone puts something in that keeps the door from closing all the way.
Back in the day, Frigidaire was a General Motors brand. Consumer Reports gave a not so good report on a Frigidaire unit and a great report for a Montgomery Wards model. In reality they were the same refrigerator with different branding badges. After a few similar faux pas my opinion of Consumer Reports leads me to not give them much credence.
