coleman evcon bgu furnace

[Edmund Forsthe]

any coleman afficionados out there, got an old bgu furnace with a bad board replacement entailed rewiring the limits can not get furnace to work inducer cycles on and off four times and give a fault of bad limit checked all by the intructions and can find a problem

[Edmund Forsthe]

after much ado and argument with the boss i finnally fingered it out ,the heat exchanger high limit is taken off the pressure switch and the board wants to see 24 volts right away or the board will cycle the inducer 4 times and lock out
