*WARNING, BEFORE REMOVING OR INSTALLING ANY PC BOARD SHUT OFF ALL POWER TO THE MACHINE. DO NOT TURN POWER BACK ON UNTIL ALL CONNECTIONS TO THE PC BOARD HAVE BEEN PLUGGED IN. FAILURE TO FOLLOW THIS PROCEDURE COULD CAUSE SERIOUS DAMAGE TO THE PC BOARD AND VOID THE WARRANTY. All pc boards listed on this page have been tested in actual machines. Should the pc board you order not work when it arrives we will replace it under our 90 day limited warranty plane once it has been returned to us for examination. Should we find that the board has been miss handled, blown up due to negligence or failure to turn power off before installing then these actions void our warranty. Should your machine have another problem and the pc board does not fix your machine then remember that we do not accept returns on electronic parts. Should you order the wrong pc board for your machine then we will gladly exchange it for the correct pc board providing you pay the postage both ways.
