Goodman furnace no gas , 3 blinking

I have bought a new ignitor and have cleaned the other stem on the far right gun. no gas is even getting to the furnace im guessing. i have followed the instructions for reigniting the pilot. All i get when it kicks on is the blower. No gas is coming out of the guns. Also, i get 3 red blinking flashes when it trys to kick on. Very frustrating Thanks for anyone who can help

3 blinks is a pressure switch error clear the hose going to the inducer housing you may need a paper clip to stick into the barb fitting on the motor housing

I had the same issue... check the hose that feeds off of the blower motor to the pressure switch,( if you dont know where the pressure switch just follow the yellow wire to the switch. there should be a hose that feed off of it at the bottom. check and make sure its not cracked, or slipped off. mine got brittle and broke off. went to home depot and got replacement hose and reset the system and now it works great

Most likely the gas valve needs replacing.

I had a problem when the gas valve not opening but gets 24volt ac after the ignitor cycle. Changed the gas valve and working like new again..

Check the gas line. It's either clogged, or run out of gas. Also check the gas valve, as well as the solenoid
valve if it has one. After all of these items are checked,
and everything alright, then your unit must run fine.

Furnace was working fine and just stopped working...it reacts to raising the thermostat but doesnt actually flame on


This is probably a ignitor.


1. Thermostat calls for heat. 2. Draft inducer motor starts. 3. Pressure switch attached by a small plastic or rubber tube senses the negative pressure produced by the draft inducer and closes. 4. Draft inducer runs for 30 seconds to a minute before you hear a gas hissing sound. The ignitor did not glow, the flame sensor (a small metal probe about 1/8" in diameter, with a white porcelain base) does not sense the flame, so after 8 to 10 seconds the hissing sounds stops with no ignition of gas to heat your home. Your furnace shuts down and goes into a lock out condition until you turn your power switch back off and on again. Then the sequence starts all over again with no ignition of the gas. Solution:You probably need to purchase and install a new ignitor. I would suggest that you inspect your ignitor closely for cracks.Make sure you do not touch the ignitor with your bare hands. If you do not visually see a crack, then you could have a furnace control board problem or a limit, rollout switch problem. Please see "limits, rollout switches & furnace control boards" further down on this page. The furnace's control board might not be supplying the voltage to the ignitor. If your furnace lights and the gas stays on for 8 to 10 seconds, then shuts right back off, then you need to clean your flame sensor with light sand paper or steel wool. You might need a new flame sensor, but most of the time they can be cleaned an will work well after cleaning.
Please leave feedback... Thanks...

I have a goodman furnace, the ignitor glows gas lights and then burns only a short time and then goes out, this hapens 3 times then furnace cycles out and I get a blinking light,


Do you have Natural Gas, or LP Gas (Propane)
Do you have any other gas appliances?- like an oven?
Do you have gas at the other appliances?

The Ignitor getting bright, and cycling 3 times is a normal number of 'LIGHT' attempts -- and shows that you do have a good ignitor- That is important! and that is GOOD!

However-- it sounds like you have NO GAS.-- Is that possible?
If you do have gas in the kitchen, then either the manual Shut off valve is shut to this appliance, or the main gas valve is not opening --- for any of a number of reasons-

Tell us more about what you do have in other appliances.

The Goodman Heater was installed in 2004. Thermostat set at 75F, the fan that blows CO2 out was on for about 1 minute, then I could hear the sound of the gas blowing into the furnace, but the ignitor...


Problem: Your furnace will not ignite the gas to produce heat for your home. When a furnace has a bad ignitor what I see most of the time is the following sequence of operation:


1. Thermostat calls for heat. 2. Draft inducer motor starts. 3. Pressure switch attached by a small plastic or rubber tube senses the negative pressure produced by the draft inducer and closes. 4. Draft inducer runs for 30 seconds to a minute before you hear a gas hissing sound. The ignitor did not glow, the flame sensor (a small metal probe about 1/8" in diameter, with a white porcelain base) does not sense the flame, so after 8 to 10 seconds the hissing sounds stops with no ignition of gas to heat your home. Your furnace shuts down and goes into a lock out condition until you turn your power switch back off and on again. Then the sequence starts all over again with no ignition of the gas. Solution:You probably need to purchase and install a new ignitor. I would suggest that you inspect your ignitor closely for cracks. Make sure you do not touch the ignitor with your bare hands. If you do not visually see a crack, then you could have a furnace control board problem or a limit, rollout switch problem. The furnace's control board might not be supplying the voltage to the ignitor. If your furnace lights and the gas stays on for 8 to 10 seconds, then shuts right back off, then you need to clean your flame sensor with light sand paper or steel wool. You might need a new flame sensor, but most of the time they can be cleaned an will work well after cleaning.

Heater exhaust blower comes on ignitor lights but it doesn't seem to get gas everything works but no flame and blower won't kick on the unit is brand new and was working this morning then stopped


This furnace should have a trobleshooting diagnostic led flashing light. Each blink (for example 3 blinks means open limit switch) has a particlur meaning. On the bottom panel has an explaination on what the blinks mean. But in the meantime check 24v at the gas right as the ignitors light. If you have 24v and the gas valve doesnt let the gas thru then the gas valve might be defective. I usually put 24v dircetly to the gas valve for 2-3 seconds to see if gas will come out. It is loud enogh to hear as well as smell. If you dont have 24v as the ignitor tries to light then check the air pressure switch. Also follow the wire off the gas valve. One is to ground. Make sure the gas valve is grounded. Follow not the grounded wire but the other one. Find out where the 24v power stops.

GOODMAN GAS FURNACE. IGNITOR GLOWS, GAS FIRES FOR 3-4 SECONDS THEN SHUTS OFF..CYCLES OVER AND OVER. SOMETIMES IT STAYS ON...THEN SHUTS OFF BEFORE TEMPERATURE GETS UP TO THE STAT SETTING...


I suspect that the flame is not traveling to all the burners within a given time so the flame sensor is shuting down the gas valve. Clean out the flame rail where the flame travels and carefully brush off the flame rod with an old tooth brush.

Goodman furnace


you should not need the owners manual. most likely you will find a chart listing the diagnostic codes on the inside of the door to the blower compartment. diagnostics are printed next to the wiring schematic. the most common problem on this style furnace is just a dirty flame sensor. a small piece of fine grit sandpaper and a 1/4" nutdriver is needed. the sensor is located in front of the burner on either the far left or right. be carefull....(do not remove the hot surface ignitor that has two wires). you want the part that has only one wire connected to the sensor under the buner. pull it out and sand the dirt off of the metal rod. reinstall and enjoy your heat

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!
