3 amp is standard.the fuse is blowing to protect the transformer.It is telling you that there is a short in the low voltage wiring.Goodman also had an issue with the coil shorting on the contactor.To prevent damage.....i'd call a pro.It should be a fairly simple repair.

You need to type GOODMAN GAS APPLIANCES into you browser to find you local servicecenter. I must tell you that Goodman only sells to authorized service companies in my experience. So you become EgKraft Company.

1 FLASH
Furnace fails to operate.
• Integrated control module
diagnostic LED is
flashing ONE (1) flash.
• Furnace lockout due
to an excessive
number of ignition
“retries” (3 total)1.
• Failure to establish flame.
Cause may be no gas to
burners, front cover

• Loss of flame after establishment.
Cause may be
interrupted gas supply, lazy

pressure or restriction in flue
and/or combustion air
piping), front cover pressure
switch opening, or improper
induced draft blower
performance.
• Locate and correct gas
interruption.

operation (hose, wiring,
contact operation).
Correct if necessary.
• Replace or realign
igniter.
• Check flame sense

I have an goodman model # gsc130241ae ac unit outside it will not come on, no hum, fan doesn't run thermostat control is good swaped out with downstairs unit. Gas heat unit is in the attic, I don't use...


Does the blower indoors run and move air? if not it would mean that you don't have power to the furnace.
The 24 volt transformer in the furnace is used to power the thermostat and the control circuit on the A/C unit outdoors. Or you could have blown a fuse on the computer board in the furnace.
If this has helped please rate me, and If you need more help, give me some more info.
Thanks,
Paul

Gooman heater connected to electronic lux 500 thermostat. no response from heater at all. tried changing batteries in thermostat.could thermostat possibly be bad. had both for approx.11 years


Remove t-stat and remove red and white wires and connect them, if unit starts then it was the t-stat.
If not go to furnace and remove same two wires at furnace and jump out at circuit board or connect wires FROM furnace, if it starts the problem is in wires.
If you have power to furnace?? and nothing happens it is either a bad board or inducer motor (little one) is not starting. Remember that their is a fuse on corcuit boards that need to be checked.

Hi Proper way on wiring furnace.


I can give you a start, For heat only, R terminal on furnace to Red wire to R or RH terminal on thermostat. W terminal to White wire to W terminal on thermostat. G terminal to Green wire to G terminal on thermostat. This will get you heat but not air conditioning.

Have a goodman furnace wont fire check light staying red no errors and i cant smell gas but my gas is on could it be there limiter switches there two upper and lower please help


Probably not, take a small piece of wire and open up the furnace. On the control board find the R and W terminal. It's ok to touch the terminals because the door safety switch will be open. Take that small piece of wire and jump the R and W terminals. Then hold in the door switch to see if the furnace starts. It may take 30 seconds or so so tape the switch closed. If the furnace starts you have either a bad thermostat, broken thermostat wire or a lose wire. If it still does not operate, you have a bad circuit board.

Furnace integrated control module


The light is supposed to be on, if there is a fault in the furnace the light will begin to give u a flash pattern... ie; three flashes...or two flashes.. on the furnace exterior or on one of the doors there should be a fault code chart.... read the chart on the unit it will tell you what light is on and when..

Turn breaker on to furnace and the exhuast fon comes and ac will not come on


There should be two separate breakers for the cooling system. The furnace breaker you turned on. Now there should be a double breaker in the power panel labeled A/C or Air Conditioner. In addition there should be a disconnect at or near the outside unit. Make sure it is in the on position also. Set the thermostat to cool and the outside unit should start and run.

I don't know where you are located, but there is a Goodman distributor in Sacramento, CA. Also in Ontario CA. They are a distributor so they may be able to help you or tell where to find someone who will help. Goodman is also known as GMC or Janitrol.
