I have a Kitchenaid Superba free standing gas range. Had a transformer blow in my back yard and it took out the circuit boards on my oven and dryer. Repairman replace the circuit board under the control panel and a circuit board on the lower right side of the oven. He said the lights came on and the burners lite but he never checked the oven. Said it may be in Sabbath Mode or may need the be reprogramed with a series of buttons pushed in correct sequence but said tech support is closed until Monday. Any ideas anyone? Getting a F1:E3 code after he left and oven still does not work.
