Bill T Dixon , MO April 17, 2015 Error code f0 1 main circuit board failure After diagnosing the problem, I went to the AppliancePartPros.com website and found the correct replacement part. I ordered it and it arrived very quickly. The repair itself took less than 20 minutes, and I saved hundreds of dollars over calling in a repairman in to fix the issue.
