i have a sears model 790.94462702 electric oven that has been taking a long time to preheat. Tonight it was preheating for almost an hour to get to 350. i finally gave up. What’s wrong with it?

  1. Hello robo76. You could have a problem with the hidden bake element in the oven. You can unplug the range to disconnect electrical power and remove the bottom panel to check that bake element. You should see 2 thumb screws at the back of the bottom panel inside the oven cavity. Remove the oven door as shown in your owner's manual if necessary to reach those screws. Once you remove those thumb screws, you can carefully lift up on the back of that bottom panel and move it back slightly to release the panel from the front lip. Remove the panel from the oven cavity and examine the bake element (with the range still unplugged). If that element is damaged, then it will need to be replaced. You can visit the Sears PartsDirect website to order that part and replace it (with the range unplugged). If the element is okay, then you could have a wiring failure or a problem with the electronic control board in the console. A temperature sensor problem could also prevent the oven from heating properly. If you need to have a service technician examine and repair the range, you can schedule service by calling Sears at 1-800-469-4663 (1-800-4MY-HOME).
