UPDATE: Zman Technologies Statement on GE Ovens Certification

Last night, TLS reported that the Star-K was no longer certifying GE ovens.

Today, Zman Technologies issued a statement and clarification with regards to these ovens and more.

They stated, “For the last few years, GE Appliances has been working in full partnership with Zman Technologies and Rabbi Tzvi Ortner to provide the best Shabbos solutions for the Jewish consumer.
All GE cooking appliances when used with Shabbos Keeper remain certified kosher for use on Shabbos and Yom Tov under the OU, CRC-Hisachdus Harabonim- according to the strictest halacha standards.

Shabbos Keeper by Zman Technologies uses an Enhanced Shabbos Mode to ensure appliances are strictly kosher for use on Shabbos and Yom Tov.

Above the standard Sabbath mode requirements, Enhanced Shabbos Mode automates heating elements and flames to ensure user activity has no affect on the appliance or it’s functions.

This allows the oven door to be opened and closed as many times as necessary throughout Shabbos and Yom Tov – even while the oven is running. This is a first time breakthrough achievement that was never possible until today.

Also unlike standard Sabbath modes, Enhanced Shabbos Mode completely controls door switches (including safety shutoff), lights, buttons and sensors so that no electronics are affected by the user.

Of course Shabbos Keeper also syncs with the Jewish calendar to automate Shabbos mode each week and every Yom Tov- for the next 30 years. This ensures there are no mistakes and you never forget to put your appliance in Shabbos mode.

Each of our certified appliances undergo thorough quality control procedures, field testing, and kosher lab-testing at GE Appliance Park in Louisville KY to ensure strict halachic compliance. It is our high kashrus standards that earned Shabbos Keeper certification from three top-tier kosher agencies and approval from many other community rabbonim.

Shabbos Keeper now supports more than 30 GE ovens. Over the next few months, look out for additional support across the full GE brand lineup including GE, Profile, Café and Monogram. These will include wall ovens, slide in, pro-ranges and more.

Zman Technologies will continue to provide you with the highest levels of Shabbos compliance in the appliance industry.”

  1. This didn’t really provide “clarification” as to why Star-K withdrew hashgacha. Unless they’re implying GE didn’t see the need to be paying for 3 hashgachos.

    • What’s so hard to understand?
      Zman technologies is an add on with royalties or such for GE vs. Shabbos mode which is included in the cost of the appliance. Which makes more business sense for you if you were GE?

  2. I think they are clarifying without saying, that GE is transitioning to a better hechsher, more complete. That’s what it sounds like to me.

    • You seem to be correct in your assumption and I take back my earlier one. I just read the Ami interview with the CEO of GE Appliance and Zman Technologies. They really believe it’s an enhanced Shabbos mode system – and it probably is as it takes care of many more issues than the built-in Shabbos Mode does.

  3. Seems like this was a financial decision to discontinue with Star K and the star K is not open enough to say it as it is that it’s not a kashrus issue but rather a financial issue.
    A kashrus agency that really does care about the consumer would be more clear and state that our business partnership is being discontinued but the Star k obviously can’t handle the truth

  4. I feel like the person on Rabbi Shmuel Kunders tape the longest PESACH. Is it PESACH today or not?

    I am more mixed up now with this article, then before.

    Can someone please explain?


  5. Note that GE recently sold off its appliance business to another firm that is keeping the GE name on the appliances.
    The new owners and Star-k (my guess) couldn’t come to terms on either money or some technical issue (my guess is probably money).
    From the context of the letter it seems that the OU and Satmar, as is with many poskim, didn’t like the workings of the old shabbos mode and are now certifying and recommending the new “Enhanced mode”.

  6. These two letters only relate to the ovens with no mention about the refrigerators.
    Also they do not discuss whether it’s permitted to cook with them on Yom Tov as claimed by the Star-K, disputed by many.

  7. Zman isn’t mentioning that now it’s going to cost us an extra $200 plus per appliance in order to pay for their device.

    Zman, although good in theory, also has bad points, such as they have two choices, take it or leave it. The damager is either one thing or it’s the other. This means if you were recipes call for a different temperature, such as if you would like to bake a cake, you can’t do that because the temperature isn’t what you needed to be.

    I for one plan on writing into GE, letting them know that this was a huge mistake on their part.

  8. I’m an appliance technician and the GE enhanced mode is the best from a halachic standpoint.

    Cooking at one temperature? Recipe? GE mode keeps the functions Non-interactive. In English that means you don’t affect the electronics. With the standard modes you do. Absolutely.

    Pay for Shabbos and Hashem will pay you back.
