SOURCE: Goodman GMS90904CXA Wont ignite, light blinks 3 times

Ok, you either have a inducer fan issue or a pressure switch issue or a plugged vent pipe. The inducer turns on to establish a draft for the exhaust. If it is not working you will get this error code. If the pressure switch does not sense pressure caused by the inducer, it will give this code. If either the intake pipe or exhaust pipe is blocked (even y just a little) it will give you the same error code. If the condensate hose or receptical is plugged, again it will give you this error code. Good Luck!

SOURCE: goodman furnace blinked 1 time

Furnace attempted to start but failed after so manay tries. This may help you.

Sequence of operation, Gas Furnace.

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 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).

This is why we technicians earn the big bucks!

SOURCE: goodman GMP075-3 Has 1 single blink on the light

The blink codes are differant on every furnace. Read your code on the schematic found on the inside of the door. You most likey have a dirty flame sensor. Under the burners you should find a "single" wire going to a connector. This will be to the far left or right. Just opposite of a "two" white wires going to the hot surface igniter. Remove the 1/4 inch screw closet to the single wire under the burner. carefully pull out the flame sensor. Clean it with a small piece of sandpaper. Re install it. This should fix your furnace. KEEP IN MIND Goodman GMP models are noted for defective heatexchangers. Pull out the blower assembly and turn it over. If small rings about the size of a dime falls out.... this furnace is unsafe and should replaced!

SOURCE: LED light blinking constantly

short in a/c wires on contactor is bad, disconnect wires at a/c and power up if no pop fuse it is the contactor. if still pops replace wire.

I'm thinking the heat blinking means its calling for heat and its not completed the Rh to W1 circuit yet. Once the circuit closes, the blinking heat will go steady....usually. Or if the thermostat is satisfied, it will stay steady and not blink...

I guess your thermostat could blink whether its mode is satisfied or not because I am not familiar with that particular stat. You forgot to say if the furnace is gas or electric heat, so if its gas, it sounds like it could have misfired and locked itself out. Go to the furnace, and cycle the power switch that should be mounted on the side. This will reset the controller and give it another attempt at firing correctly. If it continues to lock our after several attempts and you still have no heat, you have no choice but to call for service.

If its an electric furnace, there isn't much you can do but call a technician for a service call.

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.

Turned my furnace off while going away on vacation. When I came back, the furnace would not turn back on. Lockout light is blinking.


with some thermostats you must cycle the power after a lockout relay energizes, so turn the stat off and back on and then check operations to see what caused it to lockout, often the lockouts are on low and hi pressure safeties, so you may have a refrigerant charge problem

I have a Rheem Furance that has turned off. Just a few hours ago the main fan turned off. The Furnace doesnm't light even the draft fan does turn on and then the main fan blower motor turns on. I can hear...


You will need to reset the furnace by turning the power off to it. Then as the furnace tries to light, watch the LED for blinking. Hopefully it will give a code other than 1. Try checking the air filter for blockage, make sure all hoses are free of moisture and any drains are not blocked. Check the air intake and exhaust pipe for sags where water could block it.

The sequence of operation is this:
Thermostat calls for heat, the LED may blink telling you it registers the call. The inducer (exhaust) blower starts closing contacts in the pressure switch (small disc shaped thing), the igniter glows orange (seen thru a small window high up on furnace front), gas valve opens allowing main burner to light, flame travels to all other burners, flame rod senses flame within a few seconds and keeps gas on. Room air blower starts within 90 seconds.

Any deviation or delay in this sequence and it goes into lock-out.
