20 Most Recent Goodman GMS807034ANA Heater Questions & Answers

First unplug your furnace to reset it then plug it back in with thermostat set to heat high enough to make the heat come on. As soon as the inducer motor came on you JUMP the 2 wires that go to pressure switch. Your igniter should come on and gas valve should open for heat. If the flame stay on the blower should come on after a few minutes. If it get to this point your problem could be pressure switch itself or inducer clogged.

hot surface igniter may be weak. if it doesnt get hot enough it will not ignite the gas

This can be due to a dirty flame sensor or a high limit switch tripping. Clean the flame sensor first, this is a metal rod on the opposite side of the igniter, take steel wool and scrub it, then reinstall. If this does not work then the limit switch is tripping due to dirty filter, dirty blower wheel, weak blower motor. Aything that restricts airflow will cause the limit switch to trip.

3 blinks is the pressure switch not working

OK, I think the flame thing may be an igniter. So the inducer turns on, the igniter glows but the gas valve does not open so there is no ignition. Sounds like you may have either a bad gas valve or a bad circuit board. You will need to check for 24 volts at the gas valve. If you get voltage but no ignition, replace gas valve. If you get no voltage at gas valve, replace the circuit board.

This motor is no good and needs to be replaced. humming means it is getting power to it but is it getting enuff? I think from the sound of your problem the brushes are bad or it could be a worn armature. When the power is disconnected does it turn freely it probably does. If it doesnt and is still stiff you could oil it to free it up and then it may work

The symptoms seem to be related to the main blower motor and/or it's capacitor. Turn the system off for a couple of minutes and then turn just the fan on while the thermostats heat setting is in the off position. If the lights still dim then replace the motor and capacitor. The clicking noise is the fan relay.

Sorry to read about your heater problem.

Chances are you have a defective glow rod, this is the electronic pilot lite for the system, i would guess its not lighting the gas for heat

THIS IS A GAS PRODUCT, INCORRECT REPAIR CAN CAUSE A EXPLOSION, AND DEATH CAN OCCUR. IF YOU DO HAVE THE PROPER TOOLS SUCH AS MANOMETER AND LEAK DETECTORS, I SUGGEST YOU CONTACT A SERVICE COMPANY.

Does the inducer motor come on? If so doe the ignitor spark or glow bright red?

SOUNDS LIKE THERE IS NO GAS GETTING TO THE IGNITER, GAS VALVE COULD BE BAD

Hi,
One of your rollout switches has tripped, reset it and you will be going again. Check and try to find out why the rollout tripped in the frist place though...

You can see the instructions here on page 39

This manual takes awhile to download but if you have one of these firnaces I would download it and save it for future refrence.

I hope that this will help you to solve your problem!

Thanks for using Fixya!!

It sounds to me that your air flow is restricted somewhere. The first thing to check is your air filter. If that gets real dirty your restricted air flow will cause the hi-limit(hi temperature limit switch) in your heat exchanger compartment to over heat and open up your gas valve electrical circuit,thus, shutting off the gas to your burners. After the hi-limit switch cools down the furnace will go back to heating again then it will overheat again(you get the picture?) If it keeps cycling on and off like that the house will never get warm if it is cold outside. If your air filter is reasonably clean(you should be able to see light thru it easily) then the secondary heat exchanger could also be dirty, this is located above the indoor fan housing, you would need to pull the indoor blower assembly out of the furnace and look up above. The secondary heat exchanger looks similar to a radiator will fins. You can use a medium stiff plastic brush to brush the dirt,hair, whatever off of it. Another problem spot would be the cooling evaporator coil (if you have central airconditioning) located most likely above the furnace in the plenum(if your furnace is in a basement). This usually is difficult to access if an access cover wasn't installed when the airconditioning was installed. I would recommend an experience service tech to clean it for you. Also make sure all you supply air registers and return air registers are open . These are the things I would check first. Good luck!!

need to clean burners causing delayed ignition.

This is a good one! I would check for a blocked vent or intake pipe first. Also check to make sure the condensate lines are free of moisture or debris. What is the code for three blinks?

You will need to have a service technician come out. It could be a fuse out on the board, a bad board or several other problems in the circuit that can only be determined by a professional on site.

Traced wires and found the wires to the humidifer were the cuprits. I beleive the solenoid may be no good. After disconnecting the wires to the humidifier, A/C and Heat are working fine now .

Is the hole on the outside unit. If may be to stop the condensate drain pipe from freezing on the elbow. Google Goodman (model) installation manual https://www.google.com/search?q=%E2%80%8BGoodman+(model)+installation+manual ..
