My oven contol panel went blank. Opened the door, the light came on but that was it.
I just recently replaced the ECB. Turned power back on, to get:

PF (power failure I assume)
then five beeps followed by F5 E1
then five beeps followed by E1 F2

Keyboard does not work. Touching any key makes no audio beep, nor does it result in any oven action.

Bad ECB?

or Bad Control Panel assembly?

I did try playing with the ribbon cable considerably as I read that this may be the cause but could get no response.

Thoughts?
