Diagnostics and Service Information
Control Voltage
WARNING: Components are electrically HOT on control when voltage is connected to oven. To prevent electrical
shock, use extreme caution when diagnosing oven with outer covers removed and power on.
Note: Mode and temperature selection is necessary for operation of relay contacts. This model incorporates
Double Line Break, meaning there is no voltage on the elements when the control is in standby.
