Timeless E Mansfield , MA October 30, 2015 5e error code My Samsung over-the-range microwave started beeping on its own. Then a few days later "E5" was on the display and it was dead. I googled the error and found out the cleaning the ribbon cable sometimes fixed the problem, but I only wanted to work on it once. I saw post where the Control Panel Assembly was replaced to fix the problem. I ordered the part from AppliancePartsPros and choose standard shipping. The part still arrived in 2 days, and replacing the part was relatively easy. A lot cheaper the a service call or buying a new microwave. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
