Mark A Elkgrove , CA December 09, 2014 Appliance: Samsung Microwave SMH9187W/XAA Samsung Microwave Smh9187w/Xaa / : E5 code on my samsung microwave. How to replace Control Panel Assembly. I removed the two screws from the top cover and took it off. (opps, I unplugged the MW first) I took out the one screw from the control pad and pulled it out. I snapped a picture of the wiring then removed the wires. I cleaned all the connections and reassembled. The code went away put not all the buttons worked. I called Appliance Parts Pro and talked them about my issue. They recommended replacing the touch pad. They gave me two options on the replacement parts. One was just the unit I needed, the other included the plastic cover. I choose the more expensive one which was still cheaper than what I saw on E-bay. I asked for normal delivery. not rush and was surprised when my part arrived 2 days later. It took 10 minutes to install the new control pad, and my wife is happy to report that I am still King of his castle. Thanks for the great service and advise. I am no electrician by any means but this job was easy thanks to the info I received. :) 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
