Lance P Oak Harbor , WA January 05, 2019 Appliance: Samsung Microwave SMH9187ST/XAA Samsung Microwave Smh9187st/Xaa / : The control panel was giving the SE error code and the grille assembly had broken tabs. How to replace Grille Assy. After trying some cleaning to get rid of the SE error code, I ordered a new control panel and a new grille. Both took about 6-7 days to arrive; the Xmas and New Years weekend slowed delivery down. The parts came well-boxed and protected. The plastic film on the control panel wasn't applied by the factory with the same quality process as the original, so along the edges there were small bubbles of air and overall was not applied as well. However, it's not a big deal. The installation of both new items went well and just took some care in getting the old parts out and the new ones installed. Works great now.
