Ron M Page , AZ July 24, 2015 Appliance: Maytag 27" Built-In Double Electric Oven Convection JJW9627DDW30 Maytag Oven Jjw9627ddw30: Control board had no display reading. How to replace Oven Electronic Control Board. Removed oven from wall cabinet to access the control components. This double oven is very heavy. Remove both doors to lighten the load and have two strong boys available to assist removing the oven from the wall cabinet and setting it down on the floor. After verifying 110 volt ac power input was going into the control board and there was no display reading it meant the control board had failed. Control board has quick disconnect cables and was easy to replace. 8 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
