Thought I'd post a quick DIY guide and let you know this repair of the keyboard only cost me $120 (parts + shipping).
This is based upon my
Model ZSC2001FSS02
wallmount model. Keypad broke in 24 months of use... not bad for a $2500 microwave... not!
0. Order the keypad/chrome trip plate (#68 in the diagram).
1. Turn off breaker to the Advantium oven and remove rotissarie plate/frame from inside oven.
2. position a tall platform with a blanket on it (sawhorses or stools) to set the oven on when you remove it from the wall... it will probably have an armored cable attached to the back that might not be easy to remove... so you'll have to work on it in front of where it was mounted.
3. Open the microwave door... remove the four screws on the sides mounting it to the cabinetry.
4. With help (it's about 120 pounds), slide the oven forward and onto the work space, being wary of it's electrical cord.
5. Remove the screws holding the top panel in place. Remove by tilting the panel backside upwards to disengage the lip on its front side.
6. Now, with a long magnetized philips screwdriver, remove the four screws which hold the front keypad assembly to the oven.
7. Remove the front stainless keypad assembly by sliding it upwards off its pegs which are on either side. (Lift it straight up)
8. Follow the set of black/white wires from the keypad assembly to the main electical board near the back of the oven... disconnect the rectangular plugs from the main board carefully (they have a small latch on them).
9. Remove the stainless keypad assembly with wiring from the unit and place upside down on a padded towel to avoid scratching the old (and the new) stainless keypad assembly.
10. Remove the knob from its post... careful and slow... it's REALLY on there. I was able to use my fingers only...but it was a workout.
11. Remove the three screws holding the rotary knob circuit board from the black plastic base. (This will allow you to remove the black base from the stainless keypad surround.
12. Disconnect the flat ribbon cable by pulling outward on the black plastic sleeve. (You might want to practice re-inserting it... and see how far in it really has to go to bottom out and be firmly inserted.)
13. Remove the screws holding the black base to the stainless keypad surround, and remove the black base... it is held in place by a small metal tab under just to the side of where the rotary knob circuity board was prior to you removing it.
14. Remove the four brackets from the old stainless surround and save for the next step.
15. Now get your new keypad and stainless surround, lay it on the soft towel, and mount the old four brackets to the new piece.
16. Now reverse install everything. Remember, the black plastic base that holds the display will NOT go back into the new part if the knob shaft is installed... that has to be installed AFTER you mount the black plastic base onto the keypad stainless surround.
Reverse everything and then power up. The display should go completely lit (all pixels) for about 15 seconds, and then you set the clock. If you can set the clock... you are good to go.
Good job!!!
