Hey guys, had a goodman gms80403an-12040013772 furnace. tech support said to replace board and we did. whats going on is inducer goes, glows,and hear gas valve click a bit and flutters, have good gas to unit.if i put 24volt direct to gas valve it opens properly and dumps gas out. i tried jump all interlocks and read 24 vlts to gas valve for a couple seconds. another tech support said harness,another said no. we widened pin connections on board plug also.They kept bringing up bad ground.The unit is almost 5years old as well as the home.Could this be the problem?I told home owner to get electrician to prove that ground is in tact from panel to attic furnace. They still have no heat and the tech support seems to be all over the place and we are running out of things to check.Any help would be very helpful as we are getting frustrated! thx
