Randy S Houston , TX June 24, 2017 Appliance: Maytag 30" Built-In Microwave/Electric Oven Combo Self-Clean JMW9330DAB16 Maytag Oven Jmw9330dab16: The control panel was no longer working lights were not coming on no beeps could be heard hen you hit a key on the control panel it first started with the 3 6 and 9 keys and became worse. How to replace Control Panel. I replaced the old control panel with a new one. I also changed out the door seal to help prevent the control panel from going bad a second time. It was the heat from the oven getting to the keypad on the control panel that caused it to go bad. 4 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
