Thaddeus G Conway , NH July 08, 2015 Appliance: Samsung Built-In Microwave Oven SMH9207ST/XAA-0001 Samsung Microwave Smh9207st/Xaa-0001 / : Control panel buttons broken. How to replace Assy Control Panel;Smh92. Replaced control panel. The biggest challenge was removing the circuit board and metal shield. I decided not to remove all the wired connections. Instead, I unscrewed the circuit board with connections in place. Removing the metal shield required patience since it is a snug fit with several plastic tabs holding it in place. Installing the shield in the new control panel was easy. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
