Hi!What you can do is try to find the tech sheet in your oven. The tech sheet is a piece of paper that will help techs when diagnosing the unit. It usually contains the error codes for your unit. It can usually be found either behind the unit, or, if you pull the bottom drawer out, it can be behind the drawer or along the tracks inside the oven.If you have any questions, please post them here. If not, please click accept. If you are satisfied, please leave me feedback so that I know how I am doing. Thank you!
