This guide explains how to make use of various types of ovens on Shabbos. It provides helpful pre-purchase advice as well as important usage guidelines.

1. Which ovens carry a Kehillas/FedTech Hechsher?

Fisher Paykel (click here) and Smeg (click here) have emerged as market leaders and have been the first to achieve Sabbath compliance certification from Kehillas/FedTech for their oven’s Sabbath mode.

Click on the links above to find out more about each company’s ovens.

FedTech recommends these ovens as the ideal way of using an oven on Shabbos or Yom Tov.

2. My oven has a ‘sabbath mode’ but is not listed as having a Kehillas/FedTech hechsher – can I use it on Shabbos?

We recommend that you contact us directly for guidance about use of any oven which does not have a reputable hechsher.

In recent years, ovens have been produced with ‘Sabbath Mode’s  which were found to be non-compliant.


At FedTech, we have long argued that ovens do not need a Shabbos mode; they must instead be Shabbos compliant.

We advise the Kehilla to take a cautios approach to the use of any oven on Shabbos or Yom Tov. Only after the device has been carefully reviewed should it be considered for use on Shabbos and Yom Tov.

You can contact FedTech here to check whether the oven you plan to use is Shabbos compliant and instructions on how to use it.
