To access the control panel components, remove the screw at the top of the control panel and pull the top
of the control panel out and down (see drawing below). A wiring diagram for the oven is located on the side
of the control panel assembly. When the control panel is folded down, all power to the control panel is
cut off by a shut down switch that is located directly behind and below the control panel. To re-
energize the controls for troubleshooting, pull the white plunger on the shut down switch up.
