This 5 yr. old microwave started dispaying an F3 error code, beeping and the touchpad was totally unresponsive. After researching on GE Support website and reading on this forum, it seemed that the solution was to replace the touchpad/control panel. I ordered p/n AP3418746; received it today and installed it. I still get the F3 error code. After plugging in power cord, the display show "Press Clock" but does not recognize when I perform that function, then eventually displays the F3 code and starts to beep. What else could be wrong? Is the "smart board" possibly bad?
Thanks for your help.
