Steven S Hurley , NY June 17, 2016 Appliance: Maytag Electric Dryer MEDB850WL0 Maytag Dryer Medb850wl0: Maytag bravos electric dryer broken and had bad display after power failure. How to replace Electronic Control Board. After utility power returned the display shows 3 dashes after rotating the knob. Trying the tech sheet diagnostics generated a different code every time I ran it. More than a dozen different error codes, many of them not even defined. Another sign is some functions of the User Interface Control Board not working; like LED's out and simple functions like the drum light not working. The fix: replace USER INTERFACE CONTROL BOARD. 4 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
