The is a tough one if there is no tech there. I have not heard of this problem as yet. There could be a loose connection in one of the ribbon cables or it could just be a defective board.
You can try putting it in to test mode to see if it can self diagnose itself.
Press 'favourite' and 'settings' at the same time, 'diagnois' will appear, press them again and the prompts will appear. Note make sure the top surface is clear as well as the oven. If an error pops up at least you will know what is wrong with it. There is also a tech sheet on the back with the fault codes.
side note, do not put alluminium foil on the bottom of the oven cavity.

F1 touch pad / ERC test This simple test will help determine
whether the ERC (Electronic Range Control or Clock) or the touch pad is
defective when F1 error code is present.
Note: Some models incorporate the touch pad in to the ERC as a single
assembly, in which case this test is not necessary. Simply replace the ERC
(Clock).
Warning: If you feel in any way uncomfortable performing this test or
making this repair, please contact a qualified appliance repair technician.
1. Disconnect power to the range (unplug the range power cord or turn the power
off to the range at the circuit breaker). It is very important that the power
to the range has been disconnected, so please double check before continuing
2. Gain access inside the control panel.
3. Disconnect the touch pad (also called keypad or membrane switch) ribbon from
the ERC
4. Make sure there are no lose wires, or anything else that may cause a short
when power is turned back on. Assemble the control panel back the way it was
5. Turn the power back on.
6. Wait for at least one hour to see if the F1 code comes back (usually
accompanied by a beeping sound)
7. If F1 comes back, replace the ERC. If it does not, replace the touch pad.
