Two screw hold the clock in place, after removal and disconnecting the plug-in you can reinstall the new clock control. The Heat Sensor inside the oven will also need to be replaced. It is located inside the oven and attached with two screws; the back of the oven will need to be removed to unplug. Reverse removal procedure and turn the power back on to the stove.
