Display not working

I assume yiu had the electronic oven control repaired. Sometimes the touch pad also goes bad. I have had to replace them at the same time. If the oven indicator lights showing the oven being on shows up on the display it could be that the thermal fuse behind the oven has gone out. this in in the common line and will shut down both ovens at the same time but you will get the control panel to respond to the touch pad.

When buttons are not working most of the time it is due to a short in the touch pad or the electronic control in a unit you would have to call for service if you did not know how to use a multimeter to perform ohms and continuity testing and measureing of both pieces. Usually though due to the button not working most of the time it is the touch pad though. If you have any further questions message me back Thanks again

there should be a 40 amp breaker in your electrical panel turn off and back on again to reset power

eith touch pad or control board un plug the touch pad if it returns the board is bad if it dont the touch pad is

Hi. this will only get worse. i would replace this defective touch pad asap if possible.

FO- the touch pad is faulty. replace the eoc(electronic oven control)

F2-E0 - Shorted Touch Pad (Keypad) - Check the connection between the touch pad (keypad) and control board (clock) to make sure it is secure.
Select the 'cancel' function and wait 60 seconds.
If error code reappears then replace the touch pad, or touch pad and control board (clock) if all one assembly.

you can replace touch pad and not very hard to do,you may want to replace control board also.

That error means the main control board has a internal failure. The board will have to replaced to fix that issue. If you need detailed repair help with that visit the link below:

F3 is Open oven temperature sensor circuit.
F4 Shorted oven temperature sensor circuit .
F7 Component failure.

To fix this you need to read oven temperature sensor circuit at oven temperature sensor ( approx 1000 ohms at room temp); check for cut or pinched wire or loss of contact, if wirings are ok, then replace the probe.
