If the display is flickering I would consider it being a bad main circuit board. If it just keeps beeping when power applied could be a bad touch pad too. Unplagging the pad and reapplying power and see if it beeps with the pad unplugged that would tell you if is the board. If it still beeps with the pad unplugged it is a bad board. It may be thinking your standing there pushing a pad. Either get both or replace the unit. Prices have come down drastically. Encompass parts was selling parts for those, sorry I do not currently have their number.

A lot of these have long screws that screw into the mounting plate behind the unit. If you take off the top trim panel look for two screw heads at each side of the unit. They will screw into the supporting plate behind the unit. Make sure you support the unit when you take them loose so it doesn't wind up falling onto the top of your stove. Those long screws do not come out only loosen so don't expect to remove them. good luck

I'm not finding that as a valid US model.

I would suggest checking the label again.

Feel free to contact me directly for more help.
