Center post on front panel broke off making use of the timer or clock impossible. Switch on top that operates the downdraft fan and stove light was broken.

Changing the complete front control module would not have been a hard job but the two screws under the left stove knob would not release and the hex wrench stipped the bolt. I was able to undo both right screws on the right knob, releasing the knob control and the right bracket that holds the center control module. Being careful I pried the two left side tabes on the left bracket allowing me to slide the control module
out. I replaced the module and reversed my steps. The top switch that controls the downdraft and oven light was simple. Remove the two screws that holds the bracket housing the switch. Remove the two hold down compression nuts by prying them up. hold broken switch next to new one and attach the four wires. Replace switch, tried to replace the two compression nuts and after a half hour figure out they are too small. Spen another half hour in assorted nut drawer until I found two small nuts and luckily was able to force thread tham on. I can't believe I saved at least $200.00 in labor doing the repair myself. (and the stove works). I'll be doing my own repairs myself from now on. (Okay, within reason)
