Matthew D Hartland , WI February 26, 2017 Appliance: Maytag 30" Built-In Double Electric Oven Self-Clean MEW6630DDB19 Maytag Oven Mew6630ddb19: Electronic control board failed causing oven temperature to remain locked (on) at 500 degrees f. How to replace Electronic Control Board. I ordered a replacement board assembly from AppliancePartsPros.com. I was skeptical because this was my third attempt at fixing the oven myself. Other companies had tried to repair the board and another sent the wrong parts. Most Internet sites said the board couldn't be found. I am extremely happy to report the electronic control board shipped by AppliancePartsPros.com worked perfectly for my Maytag model MEW6630DDB. It saved me over $2,000, which would have been the cost of a new double, wall-mounted oven. I needed a phillips screwdriver and nut driver to complete the repair, which took only 30 minutes. Afterwards, we baked a pasty and it tasted delicious! 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
