Wyatt M Spartanburg , SC November 06, 2016 Appliance: Samsung Microwave SMH9187ST/XAA Samsung Microwave Smh9187st/Xaa / : Samsung microwave se (or perhaps 5e) error. How to replace Microwave Control Panel Assembly. Internet suggested cleaning the end of the data ribbon that attaches the touch pad to the control board. GREAT suggestion! Google "Samsung microwave SE error" and find the steps. It worked for over a year. Periodically "SE" would show up; clean ribbon; all would be great for a period of time. BUT, finally it began presenting the error 2-3 times a day. Time for AppliancePartsPros!!!! Ordered new Assembly Control Panel. Removed control board from old Control Panel and put in into the new one. (Just four screws...a no brainer)! Attached new data ribbon to control board. Reattached to microwave (you can't miss...all attachments have specific shaped and color coded plugs. Just match 'em up). AppliancePartsPros even double checked to be sure this part would solve the issue. Part arrived in 3 days. Probably took less than 15 minutes to install. Now, GOOD AS NEW! THANKS APPros!!!!
