    Concord 80 Plus Gas Furnace 6 blinks
    My furnace has been working on and off for about 5 months... first it would go out completely.. and I found the wiring was loose.. then it worked for a few weeks.. now it doesn't work at all.. when I reset it the first time the LED lashed 3 times for the pressure switch... and I reset it again now it blinks 6 times for a system lockout... it starts it cycle.. lits the burners for a few secs.. then stops and repeats same process 3 times before... shutting back off... the thermostat is brand new... and always blinks filter no matter if it is if I replace it or not... Anyone have any tips
