Entered diagnostic mode did not seemed OK when unit had not run.Wouldn't enter diagnostic mode after running & lights start flashing any trouble shooting help is appreciated.
Answer Hello Greg, There are a few things you need to check before ordering parts. First remove the kick panel at the bottom of the unit. With the power to the unit turned off, remove the power connection cover/box. This is the box that contains the wire nut connections. You need to verify polarity and 120Vac. By polarity I am referring to the hot wire, neutral return, and ground. If the hot wire and neutral are swapped, this can cause all sorts of issues including premature control board failure and program deviations. also, it is important that neutral and ground are not crossed. If this all checks good, replace the control board WP8564543. Read More... Answered by AppliancePartsPros.com | Wednesday, November 21, 2012
