Have a GE PTAC that needs to have the drive board replaced because it has bad relay on it and nothing on this board is repairable so GE sells you a new board .The board number is WP26X10028 it is the one that controls all of the functions of this unit.What I need is some tips and instructions on how to go about changing this board,some  do's and don'ts and if at all possible an instruction sheet.I don't thing one will be sent with the board so I need some help.You guys have always been great about helping my out,and thanks to all of you for such a wonderful helpful forum.

None of you HVAC guys can help here?

Most boards are plug and play.  With power off/unplugged visually inspect the new and old board terminals.  They should be labeled exactly the same on the board although they may be in a slightly different location in a worse case scenario.  Simply remove one and plug into the new one.  The reason no one probably answered is because that's an eyes on repair - hard to give help for an unseen item that's specific to a particular brand.  Most of us HVAC guys are working between 1710 and 1725 hrs.

dkpd1581,thank you so much for your reply,I hope that I didnot offend you or anyone else because that was not my attention,it is just so hard to get info on any GE  units.I was woundering about static interferance with board replacements.Once again thanks so much

[dkpd1581]

The best way to get rid of the static is to keep your forearm or some part of your skin in contact with the metal case before and during handling the board.  You pre-ground yourself and keep grounded during the install.  Static can be a concern but not so much as you might suspect. In the summer the humidity usually keeps that down...in the winter may be a complete different story.  Best of luck....let us know.
