Technician would need to check to see if the proper voltage from pcb is being generated for the heater cooktop coils and the bake and broil heater elements for the oven compartment.
If not the digital thermocontrol system would need replaced.
DIGITAL THERMOCONTROL SYSTEM: Each part number is specific to the model, CANNOT be interchanged.
