David G Stillwater , MN December 01, 2015 Appliance: Model MGDE500VM F01 error code Replaced the Electronic Control Board, Part #AP4425770. Very simple and easy to do. Had some difficulty removing one of the connectors by hand, so I reverted to using the pliers. Overall repair took 30 minutes.(probably would have been done in 10 minutes if I would have given up sooner on the difficult connector and grab the pliers) Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
