whirlpool dryer

Opened the dryer light was on, filled the dryer, shut the door. Turned the timer ad hit the start button and nothing. Opened the dryer door, no light, seems like no power…this happened once before and corrected itself. Found out daughter was turning the timer backwards to set it…would the timer be the issue. When I was turning the dial I cold once in awhile hear the timer hum. Checked all circuit breakers they all are on.

I have all lights but no functions…no clicking, or any sounds, coming from the fridge when you push one of the buttons on the dispenser and then the try to get water or ice.
I have the trim piece off of the freezer door but not sure how to remove the control board from the dispenser…please advise…just don’t want to break anything trying to remove.
