Not one to ask for directions ..or help ...but
time is an issue... so blah blah blah.
furnace I am installing is GMV9115dxa-93%
Why the Amv9115dxa is 95%and this one is not is another but the customer is angry already as the 2% difference screws up his fed tax credit.
Ok here is the dilemma:
A connection on the primary limit got broken during gas pipe install. Hooked everything up and bypassed the primary limit just to see if the b*tch would fire up. It didn't fan only works, cooling fan/condensing unit comes on.heat no..but circuit board constant LED flash which manual says is reversed polarity... Ok check breaker ohm line m,ake sure it is a direct connect it is. Black hot -white neutral connected properly ok though what the F_ck. It is a goodman .Reverse it strange blower and vent fan come on and at high speed but no flahing lights... but gas valve does not no spark, no fire ... Manual also says could be bad ground. electrical I used was existing bx 2 wire 1 hot , 1 neutral and bx casing should be good for the ground.
Anyway when I put polarity back correctly same thing happened continuous flash. However when i disconnected the bypass I amde to the primary limit both blower and vent fan came on.
So any good ideas?
Getting the limit switch tomorrow and considering running new electric line to system with a direct ground not using the bx casing as ground.
But also thinking the circuit board ... Why if when the polarity was actually incorrect it did not flash this and when itr is correct it does and whenm i leave primary limit open it does not flash this?
Well hopefullythis comes to me in a dream tonite or in the morning when i check the board.
Otherwise I will be in meter-ville tomorrow chasing phantoms of Goodmanvania ...
