W Stephen W Baltimore , MD July 14, 2014 Appliance: Maytag Microwave Hood Combo MMV4203DW00 Maytag Microwave Mmv4203dw00: The se was showing and that meant bad keyboard. How to replace Control Panel. Bought the keyboard and took the microwave apart. A little more stuff to do than expected but not bad and no decisions to be made. Put it back together with the new part and it works for now, at least it tells time. We don't use it very often. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
