We had a power surge from a fallen power pole. We heard a loud "pop" come from the dryer. After that the controls would not light up and the dryer would not turn on. The light inside the drum was still working however. I was pretty sure the control board got fried, so I ordered a new one. I watched a video on how to replace it. My dryer is stacked on top of my washer, but I was actually able to perform this repair without removing the dryer. I only needed access to the top panel and I had enough room to unscrew that from the back of the dryer. With the top panel removed, the control assembly in front is accessible to remove. I left the wires attached to the control assembly (the dryer was of course unplugged from the wall). I was able to dismantle the control assembly to remove the control board and replace it and reconnect the wiring to the control board. Getting the control assembly back together again was a little difficult getting the indicator lights and control knob lined up just right. But with some patience and several tries being gentle with it so to not break anything, I was able to re-assemble the controls correctly. Once everything was back in place and I restored power, the dryer worked again. There were definite burn marks on the old control board and attached assembly, so this was definitely caused by the power surge.
