A new development has come to our attention. On many ranges and wall ovens when the door of oven is opened the fire will go off. Even in Sabbath mode, although there is a delay, it’s an exact amount of time. Fire will go back on after closing door and again in Sabbath mode there will be a delay but a specified exact amount of time. Obviously you must check with your Rov to find out if this is a problem To get around the problem you can use an oven shabbos switch that will be available at Town Appliance starting on tues, or at your local seforim store, that can override this issue.
Bosch newly manufactured gas ranges do not have a problem and the old ones will be corrected by customer contacting Bosch. Bosch, Thermador and Wolf E series wall ovens do not have a problem either.
To check if your oven/range has an issue, put it in the Sabbath mode and preheat oven.
After it reaches the set temperature wait till fire goes back on and then open the oven door. Check if the fire goes off and if it does time it a few times. If timing is random range is okay. If it’s an exact time you need a shabbos switch.
The following GE ranges do not have a problem
- Non self cleaning ranges
- Hotpoint ranges
- JGB630 JGB660 and JGB700
