Appliance is over 5 years old. I assume you mean the power board within the appliance. I have already swiched off the mains RCD switch then on again, but for less than an hour. I shall try again for an hour then get back to you.
Have switched on and no change ie RH front and back rings do not light up.
Why would half the rings still work if power board gone u/s?
If it would help I can try to get model and serial no but involves sticking my head in cupboard to read upsidedown label on bottom of appliance.
