Goodman gms80903bna light blinks once fan runs all the time,


I believe this code is ignition failure.
Turn power off and after 20 seconds turn power on with thermostat calling for heat. Vent blower should come on first. After a bit igniter should lite up. You should hear click noise of gas valve open up. If igniter does lite and you hear click noise, flame should come on for a few seconds minimum. If igniter doesn't lite and you hear click noise from gas valve, igniter is bad. If flame lites and then goes out, flame sensor probably needs cleaned. Both igniter and flame sensor are in metal plate under burners. Igniter has 2 wire going to it and flame sensor has one wire. If you think it is flame sensor you can remove with taking it out with 1 1/4" hex screw. Flame sensor will have white film on it if it needs cleaned, clean with steel wool or a dollar bill. If it isn't weither of these it is gas valve or circuit board.

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.

I have a goodman propane furnace, model # GMPN080-4 that lights for about five seconds and then cuts off. It does this three times and then stops all together. Tried lightly sanding the flame sensor and it...


The goodman furnace will try and light three time before it faults out for safety reasons. Adjust the flame sensor so that it is closer to the flame or actually in the pilot flame. If the flame sensor is inside the pilot flame and still does not stay lit, your flame sensor is probably defective and should be replaced. You can get one at Ferguson's counter sales.

My furnace wont lite


Problem: Your furnace will not ignite the gas to produce heat for your home.The following is the sequence of operation and probable cause:


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 (or circuit breaker ) 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 (use gloves). 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.

My goodman furnace keeps lighting for about 10 seconds than goes out lots of clicking sounds


Problem: Your furnace will not ignite the gas to produce heat for your home. When a furnace has a bad igniter 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.

If you do not visually see a crack, then you could have a furnace control board problem or a limit, roll-out 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.

All burners will not light on Goodman furnace


I have had problems like this before. Most of the time it is the connection between the burners. There are small slots that the gas runs thru to lite. Clean those with a brush and then try it. Rus

Goodman GMNT furnace goes into 'lock-out'.


The brain has to have constant verification of flame. If the burner ground is corroded then you will get the condition you prescribe.
