Robert S Pocatello , ID September 16, 2014 Appliance: Whirlpool Gas Dryer WGD9600TW0 Whirlpool Dryer Wgd9600tw0: F 01 error code. How to replace Control Board. I couldn't find a repair manual for my specific model, but other Duet dryer manuals all indicated that F-01 was a defective main control board. I located the board from the parts blow-ups, removed the top cover, took pictures of all the wiring, and removed the board, I verified that the part number matched what was in the parts list and ordered the board on Tuesday evening. It arrived Friday afternoon. I installed the board, connected the wiring and tested it. Everything worked properly, so I put the top cover back on and was done. Split between the two days, the repair took less than 30 minutes. The only hard part was getting a couple of the wire connectors to release (specifically the two connectors at the left of the board as it is pictured in the parts list). Some gentle persuasion with a pair of pliers solved that. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
