Product review (5 stars): Frigidaire Ice Maker  5303918277, 218699501, M1
I have a Frigidaire FRT2156A, top freezer with ice maker inside. When the ice maker quit working, I ordered this new one, which I quickly received.  The day before it came, I had a repair tech look at my refrigerator and he determined that the refrigeration unit was going out, and that the entire 'fridge was not getting cold enough for the ice maker to function.  He advised getting a new refrigerator instead of repair, which would have been nearly as much as a new one.

I wrote back to the seller on amazon.com, who immediately sent me an RA #, and allowed me to return the un-opened ice maker for full refund, though I had the cost of return shipping.  I was happy!

I learned that ice makers require a certain cold temperature, or they won't function, so always check the temperature in both sections of a refrigerator / freezer before replacing an ice maker.
