From the Star-K: “There are some new models of GE Monogram refrigerators that cannot be adapted to include a Sabbath mode.
The previously available kits are no longer compatible with these models.
If you are planning on buying one, please check the STAR-K website for more details and updated information, or call us at 410-484-4110.”
The Shabbos Keeper is great for the GE Refrigerators. It automatically starts Shabbos mode every week.
I think it is under the OU though, not Star-k….
