You are getting improper voltage to the ignitor. Check all grounds both in the furnace as well as at every connection heading back to the circuit breaker panel. If you find none, you will need to replace the circuit board.

What's your problem? goodman furnace lights, burns 10 secs goes out


Hello,sounds like you have a dirty flame sensor. This is a metal rod on the oppositenside of the hot surface ignitor. turn off power to the furnace and remove the flame sensor, then use steel wool and clean the flame sensor and reinstall. Next turn back power to Furnace.

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.

I have a goodman gmpn 100-4 REVB furnace that will not stay lit


If the igniter lights the burners the ignitor..... is not bad. Its like a light bulb.... it works or ot doesn't.
You are describing a dirty flame sensor. Dishonest contractors will sell you a new ignitor but clean the flame sensor when the are installing the ignitor. It is located at the opposite end of the burners than the ignitor. It has one wire going to it. Remove it and clean the rod with a piece of fine grit sandpaper. this should be done every year before heating season.
Good luck

Goodman GMP075-3 ignition problem


OK, if the furnace is not lighting for even a few seconds, you have either a bad gas valve, bad wire, bad control module or no gas. The pressure switch is not the issue. Check all wires to the gas valve and look for 24 volts across them when the ignitor glows and you hear the click. Then test for 24 volts to ground. It could be a bad ground wire.
