Cooking Appliances

Companies have chosen the name "Sabbath Mode" , and we are concerned from a halachic point of view that there may be some misunderstanding as to the proper use of Sabbath Mode ovens on Shabbos. We would therefore like to make some clarifications:
1. No adjustment to the temperature is permitted on Shabbos even when the oven is Sabbath Mode. 2. All food must be fully cooked and placed in the oven before Shabbos. 3. It is the opinion of...continued
Consumers should be aware that some appliance companies are advertising 'Sabbath Mode' oven features that are not certified by STAR-K or any other reputable rabbinical group. To be sure that all halachic concerns have been duly addressed, you can check model numbers from specific manufacturers on the STAR-K website or call our office at 410-484-4110.

If a self-clean feature is important to you, please be aware that many new Sabbath Mode oven models no longer have this feature.

Refrigeration/Freezer Appliances

Units certified by the STAR-K generally eliminate all items of concern when the appliance is put into the Sabbath mode. Some appliances may have features that are problematic on Shabbos and Yom Tov. This is especially true for the more expensive models, but may also be an issue for a lower cost models. If at all possible, one should see the model to be purchased, preferably up and running. The STAR-K web site has a check list to be used in evaluating a refrigerator or freezer. Recent features of concern are digital temperature display (which changes when you open the door) either inside the refrigerator, or on the door, and magnetic switches which are sometimes hard to find and defeat.

VERY IMPORTANT: The Sabbath Mode feature on your refrigerator or freezer was designed to be used on an "as-needed" basis. Make sure to exit Sabbath Mode and reset your appliance at the conclusion of the Sabbath or holiday.

Medical Devices

STAR-K certifies certain devices for use on Shabbos by a choleh (an infirm or ailing person). These devices rely on the halachic principle of grama, which means that there is a time delay between the person's action and the ensuing melacha occurring.

There are two STAR-K certified companies that make such devices: GramaChip Technologies and Movinglife. Please note that both companies make additional products that are not STAR-K certified.

These companies manufacture the following STAR-K certified devices:

GramaChip Technologies – Stairlift, Platform Lift, Ceiling Lift, Stair Climber, Recliner Chair, Suction Machine, Nebulizer, Hospital Beds, and Nurse Call Systems.
Movinglife – Shabbatto Folding Scooter.

The above devices may only be used by and for cholim, under the guidance of an Orthodox rabbi.
