Question about Goodman GDS80703ANA Open Flame Mid-Size Heater
MODEL # GMS80903BNA. MY EXHAUST FAN COMES ON BUT THE AUTOMATIC IGNITER WON'T COME ON. i CHECKED FOR POWER AT THE CIRCUIT BOARD GOING TO THE IGNITER AND NOTHING. THE OTHER BLACK WIRE NEXT TO IT HAS POWER GOING TO THE FAN. THE RED LIGHT IS SOLID THEN STARTS BLINKING.
Turn the heat up and observe the flash code....there's a legend in the furnace,or in the blower compartment that tells you what the flash sequence means...or in the Manual...........The flash code is likely for the Pressure switch...this part can either be defective or your Vent or Air intake could be blocked with Leaves,rodents,kids rocks etc...check the vent outside and look for obstructions and see that the air coming out the exhaust seems to be normal...........find the pressure switch which is round and has usually a grey small hose coming from the pressure switch and going to the furnace body or the exhaust fan....pull the hose off the opposite end (not the pressure switch...with the power off)...and slightly **** and blow repeatedly...(Really) and you will here the switch clicking....do this several times at least...make sure you're activating the switch by hearing the clicking.....Turn the furnace back on and see if it works...if it does you need a new Pressure switch...if it doesn't your vent could still be blocked or the switch could still be defective
