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.
