Check the venting for a restriction, check the condensate hose for blockage, check the pressure switch and hoses going to it. And make sure the small exhaust fan spins freely.

Heater unit will not ignite, will note fire up


Check your furnace by the electrical panel, there should be a blinking error light. Sometimes there is a legend to how many blinking lights means what. I had an issue with mine, read the code and it turns out it was hitting the high heat limit. Turns out my blower motor wasn't turning on. Replaced it with a spare and it was fixed. Find out what type of furnace, and google the name, model, and the words, 3 blinking lights. Does your furnace turn on at all? Does it start to go through the cycle then stop? This is the proper cycle of a furnace and what should happen.

Inducer motor kicks on, it runs for a little bit, about 3-5 seconds, then you should see a bright yellow glow, this is the igniter, shortly after, you should hear a click and the gas should start to flow, almost immediately it turns to a blue flame. Then your igniter should turn off and the blower motor start up.

Goodman gms80903bna light blinks once fan runs all the time,


I believe this code is ignition failure.
Turn power off and after 20 seconds turn power on with thermostat calling for heat. Vent blower should come on first. After a bit igniter should lite up. You should hear click noise of gas valve open up. If igniter does lite and you hear click noise, flame should come on for a few seconds minimum. If igniter doesn't lite and you hear click noise from gas valve, igniter is bad. If flame lites and then goes out, flame sensor probably needs cleaned. Both igniter and flame sensor are in metal plate under burners. Igniter has 2 wire going to it and flame sensor has one wire. If you think it is flame sensor you can remove with taking it out with 1 1/4" hex screw. Flame sensor will have white film on it if it needs cleaned, clean with steel wool or a dollar bill. If it isn't weither of these it is gas valve or circuit board.

Goodman 075-3 fan runs but no voltage going to igniter


One thing you can checkmis the continuity through the ignitor itself if you have continutity through that there is also some safeties it has to go through but the board is where the voltage is supplied for the ignitor. I would check the high limit and the roll out before condeming the board.

Goodman GMP075-3 Has 1 single blink on the light


The blink codes are differant on every furnace. Read your code on the schematic found on the inside of the door. You most likey have a dirty flame sensor. Under the burners you should find a "single" wire going to a connector. This will be to the far left or right. Just opposite of a "two" white wires going to the hot surface igniter. Remove the 1/4 inch screw closet to the single wire under the burner. carefully pull out the flame sensor. Clean it with a small piece of sandpaper. Re install it. This should fix your furnace. KEEP IN MIND Goodman GMP models are noted for defective heatexchangers. Pull out the blower assembly and turn it over. If small rings about the size of a dime falls out.... this furnace is unsafe and should replaced!
