It would be nice to know if this is a condensing furnace or not. With the lack of information, I cannot suggest that there could be a problem originating from a plugged condensate drain or a blocked combustion air inlet pipe on a two pipe furnace or a blocked flu pipe.
If it has only one pvc pipe, that will be the flue and it could be partially blocked with mud daubers or another critter. A blockage in either will effect the flu's positive pressure and possibly open the pancake style pressure switch causing no gas but the indoor blower will still run because it is energized off of a circuit board and not a thermal sensing switch.

Of course, you could have 80% furnace with galvanized flu connection to a masonry (or metalbestos) chimney and it won't have all the sophistication in the control circuit that the 90 percenters have. 80 percenters also have an inducer motor, but they don't have the condensing coils of the more efficient.

This probably wasn't a lot of help, but maybe the door still has the troubleshooting chart on it that tells you what the blinks mean. That should put you more in the right direction than a stab in the dark. Seldom is too much information provided within a question.

SOURCE: GMPN 100-4 furnace. Blower motor runs when not calling for heat.

The board is bad. The unit thinks a flame is present, so it tells the blower to come on. Replace the board.

Need your model # to check the codes but, this coming back on after turning the t-stat off is rare. You may have been in a lockout and the furnace re-started. Some furnaces try to start three times , then lock out. Time out, then re-start. The codes should be on your furnace blower door. Write back with this info and i could help.

I have a goodman modle gms80703ana and at first the inducer fan would kick on in it's normal cycle then the furnace would shut off do to a pressure switch. Now the inducer fan only come on perodicaly...


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.

Heater does not come on gms80703an


There are too many reasons for this to happen so we would have to narrow it down. The sequence of operation on a Goodman furnace is usually:
1: Inducer draft motor comes on
2: Hot surface ignitor comes on and glows
3: Gas valve opens, lights burners
4: Flame sensor detects flames
5: Blower comes on

If the inducer motor never came on, then you start looking at power to the unit, thermostat issues, or inducer motor issues. Just a few places to start. Hope this helps!

Our furnace keeps shutting down soon after burner ignites inducer motor stays running wont heat until reset switch behind inducer motor is pushed


Sometimes a "Flame Sensor" gets carboned up and does not detect that the furnace has ignited, so it shuts down the fuel source. Might try cleaning that if so equipped.

Goodman GMP Furnace problem. Original problem is


Good one! Is the flame getting to the flame sensor within the few seconds? Maybe a good cleaning of the burners or flame tray would help. 1.3 ma is enough for the flame rod to tell the board to stay on. Re-do all the ground connections both at the board and furnace cabinet to be safe. Check the polarity of the power going to the furnace. What are the chances the second board is bad?

Goodman GMP 125-4 one blinking light code. Gas valve has been replaced (at cost of $443). Didn't fix problem. Same co wanted $415 to replace circuit board. I did it myself for $99 part. Still same problem!...


One blink means it didn't light after a number of attempts. You replaced the circuit board and gas valve. Read on for some suggestions. On a call for heat, the 24 volt thermostat sends a signal to the control module. The control module will indicate a call for heat with a light on the control either blinking or remain solid depending upon model. The inducer (exhaust) blower will purge all gasses from the furnace and pressurize a pressure switch. Once the pressure switch tells the module to continue, the electronic ignition will energize and send 120 volts to the igniter. The igniter will glow and you will be able to see it if viewed thru the small inspection port. Once the igniter gets hot enough, it sends a signal to the module opening up the gas valve (24 volts). Either a pilot will come on or the burner tube will ignite then spread the flame to all burners. Lastly a safety sensor will be looking for a certain temperature within a few seconds and the furnace will continue to operate and the room air blower will turn on in a minute or two.

What could go wrong? The unit will not run if there is no signal from the thermostat (bad thermostat or broken wire), the control module does not sense a signal from the thermostat (bad control), the inducer does not energize (bad motor), the pressure switch does not close (blocked vent piping, bad switch, plugged condensate hose), the igniter does not energize (bad control, bad igniter), the gas valve does not open or there is no gas (bad gas valve, broken wire, no gas), the pilot does not light (dirty pilot), the burner does not light (bad burner, plugged orifice, not enough combustion air), the flame does not spread to each burner (bad flame spreader, dirty flame spreader, more bad burners), the flame safety sensor does not detect flame (dirty or bad flame spreader, bad flame sensor, broken wire, bad control), or the room air blower does not energize (bad fan motor, bad control).

Weatherking furnace is starting and stopping


This just sounds like a couple of problems. First, your blower is designed to only turn on once the heat exchanger heats up, so the flame will be on for a minute or two before the blower starts. it sounds like your blower is cooling down the heat exchanger too fast and causing it to shut off so it can warm up again...check blower speed for heat, it should be the lowest speed (black wire). Blue=medium speed, red= high speed. second problem could be your flame sensor rod is calcified, you just need to locate this and clean it off with some fine sand paper.it is located in the flames near the burners. Also change your filters, for proper air flow through your heat exchanger.

Sequence of operation on your gas furnace may help diagnose your problem.

On a call for heat, the 24 volt thermostat sends a signal to the control module. The control module will indicate a call for heat with a light on the control either blinking or remain solid depending upon model. The inducer (exhaust) blower will purge all gasses from the furnace and pressurize a pressure switch. Once the pressure switch tells the module to continue, the electronic ignition will energize and send 120 volts to the ignitor. The ignitor will glow and you will be able to see it if viewed thru the small inspection port. Once the ignitor gets hot enough, it sends a signal to the module opening up the gas valve (24 volts). Either a pilot will come on or the burner tube will ignite then spread the flame to all burners. Lastly a safety sensor will be looking for a certain temperature within a few seconds and the furnace will continue to operate and the room air blower will turn on in a minute or two.

What could go wrong? The unit will not run if there is no signal from the thermostat (bad thermostat or broken wire), the control module does not sense a signal from the thermostat (bad control), the inducer does not energize (bad motor), the pressure switch does not close (blocked vent piping, bad switch, plugged condensate hose), the ignitor does not energize (bad control, bad ignitor), the gas valve does not open or there is no gas (bad gas valve, broken wire, no gas), the pilot does not lite (dirty pilot), the burner does not lite (bad burner, plugged orifice, not enough combustion air), the flame does not spread to each burner (bad flame spreader, dirty flame spreader, more bad burners), the flame safety sensor does not detect flame (dirty or bad flame spreader, bad flame sensor, broken wire, bad control), or the room air blower does not energize (bad fan motor, bad control).

Most newer furnaces like yours will have a diagnostic center or control built into the control module. You may be able to view it as it is running thru a small viewing port. Some models will require the removal of an access panel prior to finding it. On the reverse of the access panel, there will be a diagnostic chart that will aide you in understanding any error code recorded (usually a blinking light).

• Check flue piping for
blockage, proper
length, elbows, and
termination.
• Verify proper induced
