Papi M San Francisco , CA January 17, 2017 Appliance: Samsung Microwave Hood Combo SMH1816S/XAA-0000 Samsung Microwave Smh1816s/Xaa-0000 / : Se error on the control panel. How to replace Control Panel Assy. Based on what I found on the internet, decided to replace the entire control panel rather than try to clean up the touch pad. Once I got the part from AppliancePartsPros.com (thanks for the fast shipping), swapping out the old control panel with the new one was fairly easy. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
