There is a flame sensor located in the same area as the ignitor (usually on the other end of the burners). remove the flame sensor with the power off. Then use steel wool or light sand paper to clean the silverish end. Reinstall the sensor and ToDA you are done! Best of Luck!

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.

My heater isn't blowing any heat. I hear the fan come in, and i think i hear the gas come on, but nothing comes out of the vents. The fan only comes on for a couple of minutes and then goes off.


Ok so here is a sequence of the heater lighting and the solution for your problem...
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 see the pictures below to help you identify a flame sensor.
Thanks and I hope this helps. Feedback apprec.

It doesn't want to shut off and we have no heat?


when you say it doesnt want to shut off i'm guessing you mean the fan. the fans run on a timer when the thermostat calls for heat it will come on 90-120 sec.later. turn your t stat down below room temp and it will shut off in 30-60 sec.your ignitor is most likly bad. turn your t stat back up and look at it. it should glow. furnace will try to light 3 times,you may hear the gas flow for 3 sec.during this cycle. if no glow good chance that is your problem and you will need to replace it.be carefull it is very brittle and breaks easy if tapped. be sure to turn the t stat down again or the fan will start running again.

Inductor blower comes on and runs then the ignitor glows flame comes up and burns for approx. 10-15 sec then goes out then fan comes on. Model number is PBKMLB12N0B0F I believe this is a goodman furnace.

Goodman gmnt060 3b doesn't light


check for 24vac between wires on gas valve about 5-10 seconds after ignitor starts to glow. If ignitor does not glow, check for 120 vac to ignitor after inducer goes on.
First...sequence of operation..power to W, inducer motor gets 120v and starts, 10-15 seconds later, ignitor gets 120v and glows, 5-10 seconds, gas valve gets 24v and opens, after 3-4 seconds the flame sensor approves flame and unit stays on. If this is not happening, it has to be in this sequence. Which ever is not happening and you do have voltage to that component, that component is bad. If you are getting a error code on board after it tries to light, pay attention to the code. if a 1 lock out code, that just means it tried 3 times and did not recognize a flame.

Goodman Furnace Lights But Won't Continue to Run


The flame sensor is dirty. You can not see the build up on the sensor but enough build up will change the resistance and the furnace thinks there is no flame.

To clean the sensor, first you need to locate it. it will be a sensor located in the path of one of the flames. Once you locate the sensor, open the bottom panel to turn"off" the furnce. After the panel is removed, unscrew the sensor from the frame above the jets. Use a clean rag and gently wipe the sensor several times. Place back in the cut out and close the lower panel.

The furnace should cycle on and the flame stay on for the normal cycle.
