Chris B Shamong , NJ April 24, 2015 Samsung microwave had the dreaded e5 error After trying to clean the contact several times, which didn't work, I decided to try and replace the control panel. I had to remove the circuit board and metal frame from the old panel and insert into the new panel. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
