Whirlpool Duet Sport Dryer F-01 fault control board repair
Introduction
Your dryer is not starting and displays an F-01 fault? This guide will show how to repair in less than an hour and for under 30$.
This guide may also apply for other make/model using a similar control board.
Most of the time this failure is cause by a worn out motor relay, so this is what we are going to be replacing, along with the surge supressor and the heater relay. Basic soldering skill is then required for this fix. Otherwise the control board needs to be replaced at a +400$ cost.
Note that the original Omron relay found on my board are now obsolete, I used replacement relays with same specs and footprint (see parts).
