Do you have to put a blech on an electric range top on Shabbos?
Gas and electric coil rangetops must be covered with a blech in order to leave food on them over Shabbos. In addition, the control knobs should be covered so that you do not inadvertently adjust the dial. If the rangetop has the element built into a corean or glass top, you risk cracking the top by using a blech, and it would be sufficient to cover the control knobs. | Back to Top | 5. Can Itake dry food out of my fridge and put it on top of the blech on Shabbos? No, unless the food would never get hot (120 F) in the spot you placed it, even if you would leave it there all day. However, you can take solid dry food that is completely cooked (such as kugel), and put it on top of another pot of food (such as a chulent pot) that is on the blech, even if the dry food will get hot.
