I find a fault code F3 on the display indicating shorted touch pad. Is installing a new touchpad something I can do myself? I am handy with tools.

It might be easy im not a microwave tech i do work on all other major appliances here is a quick article i copied showing how dangerous a microwave is. There are plenty of stories on how people are killed working on UNPLUGGED microwaves.
When diagnosing a microwave oven, many problems can be detected merely with careful observation, that is, with the power disconnected. Most tests can be accomplished with the power off and the oven unplugged. We suggest that you leave the "live" testing to the professionals. Nonetheless, certain safety habits must be developed and maintained. If you have experience in troubleshooting electrical equipment, some of these safety precautions may be familiar. However, the high-current potential of the high-voltage circuits in a microwave oven make them possibly life-saving steps. If you are uneasy or unsure about any of these safety procedures or warnings; or if you feel uncertain as to their importance or your ability to manage them, it would be in your best interest to leave the repair to a qualified professional.
- FIRST and ALWAYS, before attempting any repairs, make certain that the unit is not plugged in.
- Before touching any components or wiring, ALWAYS DISCHARGE THE HIGH VOLTAGE CAPACITOR! The high voltage capacitor will quite normally maintain a painfully high-voltagecharge even after the oven is unplugged. Some capacitors employ a bleeder resistor (either externally or internally) that allows the charge to slowly bleed (or drain) off after the oven is unplugged. Do not trust a bleeder resistor—it may be open.
[LIST=1] If you forget to discharge the capacitor, your fingers may ultimately provide the discharge path. You only make this mistake a few times, because, while the electric shock is painful, the real punishment comes when you reflexively yank your hand out leaving behind layers of skin on razor-like edges that are there as a reminder to never again forget to discharge the high voltage capacitor. [/LIST]
