Thank You for using JustAnswer - My name is Tony and I am more than happy to help with your question today.The control board is a non serviceable item so may need replacing.You could try remove the board in case the touch buttons on the board have bad connections.
Both sides of the board are now failing, I think I have pressed every configuration that can be done. It appears to be a power failure, but plug & switch have been checked. Is there any sequence maybe I can release time switch or child locks ?
Is there any power going to the panel, is it displaying any light indicators.If the control panel has been locked out then you would see some sort of symbol or number displayed on the control panel.Let me know what is being displayed so I can figure a way of helping you.
Switched off the unit over night & when pressing the left set of on- buttons the hobs will power up ok !
The right set of hobs are as I reported still dead. Left set of hobs working satisfactorily.No lights at all on any buttons with reference to right side.
It's most likely to be the board that is at fault.If it was just locked out then you would have indicators to all controls.Take the control board out and check the PCB for any burn marks.
