    Goodman furnace doesn't come on.blower doesn't start
    Hi, I have a Goodman Furnace GMP075-04 about 9 years old.. it doesn't come on when I switch my thermostat to heat... I replace the ignitor last year and it worked fine until now... blower doesn't come on either... I tried turning the air conditioner on and it works fine... I have went through the routine of turning off the gas, unplugged power, wait 5 min, turn on gas, plug in power and nothing... any suggestions...

    Does the furnace do anything when you turn on the heat? By the way that furnace needs a safety inspection, be prepares to replace the furnace or heat exchanger. Sorry, but your health is worth more than a furnace.

    If the system will not try to come on at all after you reset the power. You may have a vent limit or flame rollout limit tripped and they are manual reset you will have to push a button in the center of the limit to get it to reset. A bad inducer motor or inducer control will have the same symptom. You should have a blinking light on the control board that gives you the code telling you what's wrong.

    Thanks T-Top, I removed the cover panel to check the circuit board and the status light blinks continuously... the recommendation on the panel states there is an equipment problem with either incorrect Twinning or incorrect primary polarity... and the fix is to reverse Transformer secondary leads and reverse primary wires... I see the transformer but am not sure of what to reverse... there are lots of wires going everywhere and I don't want to make a simple problem worse than what is already.

    Don`t go to switching any wires,, if it worked yesterday or last week, or last month,, these wire are OK and don`t need switching,, count the number of short blings that come between the longer space of no blinking

    A fast continuos blinking light is polarity incorrect. A slow blinking light with a pause and then blinks again will be a deferent code. Have you done any electrical work on your house the past few days, any fuses blown or breakers thrown? If so the light for incorrect polarity may be correct.

    Hi guys,
    I turned the power off from my unit at the breaker and left it off for 24 hours.. after that I closed the gas valve... waited 5 minutes and turned everything on and opened the valve and my furnace lit and is working... We have heat... Thank you for all the info

    You do realize the probability of broken eyelets in that furnace at 9 years of age is very great. This failure will release carbon monixide into the house. Maybe you can put a canary over one of the registers. When he falls off his perch it is time to replace the furnace. Just a joke. Please have it inspected.

    Have your Goodman replaced with a GOOD furnace. Ggodman is crap. Mine is three months old and the "company", Park and Sons or Emergency heating and Repair in Omaha Nebraska, doesn't back his product. What a surprise, eh? The lowest bid is a crook. Get rid of the Goodman, go with a reputable furnace company. There is a reason no one has heard of Goodman. They are worthless
