WED92HEFW0 Whirlpool Front Load Dryer. 2016 model Unit powers on fine. Can select cycle and change settings. But soon as you hit the start button it powers off and a PF code comes on the display.

Whirlpool Dryer PF Error means the control lost power to the control. If you continue to get this error and you are certain your outlet is providing the proper voltage to the dryer then the mainboard is bad and will have to be replaced.
