March 16, 2016
Please note the following about the Bosch HGI8054UC and HGIP054UC models of slide-in gas ranges: The oven’s heating source shuts off immediately when the door is opened and re-ignites when it is closed, even when the oven is in Sabbath Mode. Consumers are advised not to open or close the oven door on Shabbos or YomTov while the oven is on. If you own one of these models, please contact or Please provide your name, phone number, and email address, so that the company can coordinate service.
