A Make and Model number of the furnace not the thermostat will help but I can walk you thru the operation of a typical furnace. It sounds to me that the burners are igniting properly but the flame sensor is not sensing the flame and shutting down the system. You will need to find the sensor and clean it and check the wire from it to the control board. Typically, the flame sensor is found at one side or the other of the burner box. It is a small probe that the flame hits. Depending upon your model it may have a small wire attached to it leading back to the control. Or it may be part of your auto-pilot assembly. ? At any rate, you will need to get to it and very delicately brush it off. Then inspect the flame channel. This is a trough area where the flame travels to ignite all burners. Over time, they tend to fill with rust and debris. Take a small screwdriver and run the blade down the trough. Inspect the wire that goes from the flame sensor to the control board. Make sure it is not frayed or broken or shorting out and that the connection at the board is good.

Beyond that, it's time for a technician to come.

Let us know the Make and Model of the furnace (found inside the furnace cabinet) and maybe we can help you further.

SOURCE: gas furnace wont stay lite

I'm a little confused by your terminology. You are saying you have a pilot lite and electric heat strips? Are you possibly meaning burners? Is the heater running for 2 hours straight without shutting off? how cold is it there? Lastly what temperature do you have the thermostat set at and how close does it get to the temp. before it shuts off?

Your hot surface igniter may be bad. It may be cracked which would prevent it from starting the burner flame.

SOURCE: Blower runs, Ignitor glows, no 24V at gas valve, no click....

Check the two wires coming directly off the transformer. They will be connected to the board the line voltage will be black and white and the 24voltage will be something like blue and red undo from board and check to see if you have 24 volts there. If not your transformer is bad 10 dollar part. Take it to Heating and Air parts house to replace. Let me know ken

Goodman gmp100-3 furnace The furnace will not start when I turn power on. It will hum but no click. The status light is solid red. Could the ignitor be bad? And what color should it be?


You should hear the ignitor pop. If you don't hear that pop sound, then the igniter is bad. They are easy to change, just make sure you turn the gas off and the pit-cock into the appliance and take a photo of exactly where the igniter tip is oriented so you can put the new one in the same spacing to have it ignite properly. The status light should be green when the furnace is 'On.'

Doesnt blow any heat we checked all connections furnace clicks on but never gets warm we think maybe its the heating element but we are not sure how to get to it to check


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.

My heat won't blow through the vents. The furnace ignites itself but it cuts off after a minute. I've sanded the flame sensor but it still won't work. What can I do now? I just want heat in this blizzard!


If the ignitor glows and the burners lite and then shut off, the flame sensor was the best place you could
start at.

If this is a reg gas furnace or a High EFF. furnace make sure your gas meter is not covered up with
snow.

Turn your thermostat all the way up, if the furnace
does this 3 times in a row-then it should go into
a lock-out mode. Has it done that?

On reg. gas furnace make sure your chimney is
not obstructed where it connects to the furnace.
If it is a High EFF furnace make sure the pvc exhaust
vent is actually venting. It should also have a pvc intake air vent make sure that is not clogged.

If it is a high eff furnace, turn unit off and remove
the door that covers the ignitor and burners. This is
usually a interior door with a sight glass in it. Turn
furnace on, if it lights and stays operating, then you have a problem with the intake vent

Gas Furnace Will not light


Hi, normally when you turn the gas off at the flex line valve and leave it off for awhile, the gas has to clear the gas valve and lines up to the pilot. Purge its self of air before it will light again. It will take the electronic ignition several clicks and more before there is enough gas to light the pilot and then open the main gas valve to fire the burners. Tell me, what kind of gas furnace is this when you speak of water? you say the site glass was full and you had to drain it and then the ignitor kept on clicking when it normally only took one click to light it. Please let me know the style as in a split system, a package unit, all in one, or what you have. I will wait to hear back from you. If the pilot does not light right away, then yes let it continue to click and see if it will light. On a heater with the electronic ignition control module on it or a circuit board, this is what tells the pilot coil to energize to light the pilot. It will send power to the pilot coil to open and let gas through to light and same for the main gas valve, will get a signal to open when the pilot is on. It will not open unless the pilot is lite for saftey. I will wait for you're responce.

Gas range (oven)won't lite (gas broiler works fine)


Sounds like an ignitor problem or possibly a dirty orifice. Model #'s are usually on the frame behind the bottom drawer.
