Harold D Nevada , TX July 02, 2016 Appliance: Model 401.80089700 The code se came up I looked up online what that meant and found the answer here on APpliancePartsPros. Not only did I find the answer, I found out I could fix it myself, so instead of replacing a $380 microwave oven I just fixed it. I ode red the part number DE94-01647A and looked on their site for instructions to install it. It only took me 20 minutes to complete the project. Totally recommend this place for all your appliance needs. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
