I have a goodman GMP075-3 that won't turn on. I think it is the pressure switch since I do not have a vent blockage. What is a venter and where can I find it??

SOURCE: fan only runs on high - variable speed goodman

your variable speed modulator on the fam motor it self has gone bad.
it can be easily removed and unpluged, and repaired by you
i believe goodmans are held on by 3 scres around the hub and a four wire connector back to the control
with out the exact modle of the fan i cannot help you find the modulator
but almost any HVAC supply store in your area will have it on the shelf....very common part
or they may need to order it
but its probably cheaper online somewhere
when you get the model of the var sp cntrl
type it in google
im sure it will pop up in a few hundred hits

SOURCE: Model #GMPN100-4 Goodman furnace. Vent fan

The sequence of events for furnace operation is -

Fan purge for 30-45 seconds. During this time, a pressure switch is actuated by the running of the purge fan, proving the control board the purge fan is running.

After purge and purge prove, the hot surface ignition and or spark begins. After a few second delay, the gas valve will open. The control board then monitors for flame prove through another sensor located near the burners. If there is no flame within 3-5 seconds, the gas valve closes. It will repeat this process, usually 3 times, before it shuts the system down, which requires a power down of the system to reset.

I have seen trash get into the hose between the purge blower and the purge switch. But you could be having other problems.

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.

After one heat cycle, the blower motor keeps running, even after cool down is complete. The furnace will not refire until i turn off the power and wait about 20 minutes for a reset.


your limit switch is opening up, that causes constant fan. Check for flashing codes after flame shuts off and fan continues. Check airflow, filters, lack on return air for possible hi temp limit problems.

I have a Goodman GMP 125-5 furnace. It had a 3 light code i replaced the presure switch now it is giving me a 1 light code please help


A sampling of various failure codes on a furnace:

Read one LED flash that stays on continuously to mean your furnace has no signal coming from the thermostat and will not operate. Turn the power off and check the thermostat for improper settings or connections.

Interpret one LED flash that blinks on and off to mean your furnace has locked out because it could not ignite after three tries, and must be reset. Interrupt power to your furnace for 20 seconds or lower the thermostat so your furnace does not try to heat, then reset the thermostat to the previous setting. After one hour of lockout, your furnace will automatically reset itself and try to operate as usual.

Decipher two LED flashes to mean the draft blower is not working, or your furnace has a short in the pressure switch circuit. Turn off the furnace power and repair a short or replace the pressure switch.


Read three LED flashes to mean your furnace has an open pressure switch circuit or it has an induced draft blower operating. Check the pressure switch hose of your furnace for blocks or an improper connection. Also, look for blockages in the flue, and tighten any loose wiring.

Translate four LED flashes to mean your furnace has a primary limit circuit open, possibly from loose wiring or blocked filters. Check and clean filters, tighten wiring and check the flue for blockages.

Interpret five LED flashes to mean your furnace senses a flame without a call for heat. This could be from a gas valve closing slowly or a burner flame lingering.



Read seven LED flashes as a warning of a low flame sense microamp signal. This could happen with a coated flame sensor or a lazy flame from poor gas pressure. Turn off the power and adjust the gas pressure according to the information on the rating plate.



See eight LED flashes as meaning an igniter circuit problem due to a bad igniter or an igniter connected improperly. Replace the bad igniter or check the ground wiring, making necessary corrections.



Decipher nine LED flashes to mean the high-stage pressure switch circuit will not close during a high-stage-induced draft blower operation. Your furnace may have a pinched or blocked pressure switch hose, a blocked flue or loose wiring.

Read continuous flashing on the LED to mean your furnace has a reversed polarity of 115 volts. Turn off the power and correct the wiring polarity after reviewing the wiring diagram.

My circuirt board has a rapid flashigh trouble light, and the blower does not shut off. What seems to be the problem?


with just the information you have provided, i would guess you have a rollout sensor somewhere that has been tripped. there are usually a push button reset on the goodman models. this usually happens when you have flame outside the heat exchanger and is not a good thing. i have seen some goodmans where the wiring for the safety sensors is melted from the flame rolling out due to a crack in the heat exchanger. it this is the case, you need to replace the heat exchanger or consider getting a new furnace. the safety wiring on most goodmans is usually purple. trace all the purlple wiring and see if some of it is melted or if any of the push button switches has tripped. on a high efficiency model, there will be several wires and rollout switches located along the top of the burner box above the burners.
good luck. by the way, anytime a safety has been tripped, the fan will default to the on postion as a precaution in case the furnace has got too hot. that may explain the fan running all the time.

I have a goodman gmnt 100 b furnace 2 stage when the gave valve turns on and floods the heat exchanger with flame then the squirl cage fan turns on and i loose the the flame


If you are getting flame distortion when the blower comes on it usually means a cracked heat exchanger which can lead to carbon monoxide, get your furnace checked by a qualified tech..
