Hello,
The touchpad display has gone out on this Whirlpool Gold Accubake System wall oven and microwave combination unit. Some control still exists. The microwave will operate using the add minute button, and the lower, electric oven light will turn on and off, but no display while microwave is operating. Resetting the breaker has no effect. I am trying to determine if the problem is the control panel membrane switch, or the microcomputer behind. Thanks.
