How to replace Touch Key Glass, Dbl,. Couldn't exactly determined what component was bad and the codes were not available to me. Decided to replace the 8303883 Assy, Control. When I applied power, found out that the touch screen (Assy, Switch) is not fully functioning. The off/cancel wouldn't work so. Tried to buy the ribbon but couldn't find one since it is a part of the Switch Assy. Ordered the black switch assy and finally have the oven fully operational. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
