The furnace is likely over heating and the high temp. safety is shutting it down. It then cools and starts again. Things to check: Filter, Blower wheel and indoor A/C coil. If any or all are dirty you are limiting air flow and need to clean them.

Having problem with lennox furnace Model ML193DF090P48C-02.Furnace has been working but now and getting worse furnace will kick on 20 seconds or so but nothing.Igniter does not come on.When it finally


Usually when your flame sensor gets dirty, the igniter and burner come on for approx.15 seconds, then shuts down. After 3 tries it will lock the furnace out. You have to shut the power off to the furnace then turn it back on to reset it. You need to turn all the power off to the furnace and remove the flame sensor, clean it with some very fine steel wool and put it back in. Be careful not to handle the Sensor (metal) part with your fingers. Turn the power on and set your thermostat so that it will call for Heat. That should fix, it if not you may need a new flame sensor.

Weather king select furnace


At the opposite side of the burners from the igniter there is a small metal probe/rod situated where the flame would blow across it during operation. This rod is for flame verification so the gas valve will know that the gas is being ignited. Often that probe will get carbon built up on it which will cause the furnace to light but then abruptly shut off because "the probe doesn't know there is a flame there". A fine grit sandpaper works well to restore it's conductive ability. However, if the furnace runs for a while before it shuts off you could very well have an obstruction in the vent pipe or an obstructed indoor coil. If cleaning the flamerod doesn't remedy the problem, I strongly recommend a qualified serviceperson look at it! The furnace could well be turning itself off because something is getting too hot and coming back on when it cools. Good luck.

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 Carrier Weathermaker 8000 furnace. it will not light.I tested the igniter on my upstairs furnace and it will glow and light that furnace. I can manualy light the furnace with a match. flame sensor...


If you're sure the igniter is good and the controller is sending voltage to gas valve to open, but not to the igniter then, yes, the controller is bad. The only way to know for sure is to remove the igniter's molded plug from the board and test voltage directly at the board. You should get about 100-120 vac to the igniter.

Having problems with Carrier 58RAV furnace. Goes through the motions, but gas never turns on. I think it is a problem with the LPGS. Please advise. Thanks


On a call for heat, the 24 volt thermostat sends a signal to the control module. The control module will indicate a call for heat with a light on the control either blinking or remain solid depending upon model. The inducer (exhaust) blower will purge all gasses from the furnace and pressurize a pressure switch. Once the pressure switch tells the module to continue, the electronic ignition will energize and send 120 volts to the igniter. The igniter will glow and you will be able to see it if viewed thru the small inspection port. Once the igniter gets hot enough, it sends a signal to the module opening up the gas valve (24 volts). Either a pilot will come on or the burner tube will ignite then spread the flame to all burners. Lastly a safety sensor will be looking for a certain temperature within a few seconds and the furnace will continue to operate and the room air blower will turn on in a minute or two.

What could go wrong? The unit will not run if there is no signal from the thermostat (bad thermostat or broken wire), the control module does not sense a signal from the thermostat (bad control), the inducer does not energize (bad motor), the pressure switch does not close (blocked vent piping, bad switch, plugged condensate hose), the igniter does not energize (bad control, bad igniter), the gas valve does not open or there is no gas (bad gas valve, broken wire, no gas), the pilot does not light (dirty pilot), the burner does not light (bad burner, plugged orifice, not enough combustion air), the flame does not spread to each burner (bad flame spreader, dirty flame spreader, more bad burners), the flame safety sensor does not detect flame (dirty or bad flame spreader, bad flame sensor, broken wire, bad control), or the room air blower does not energize (bad fan motor, bad control).

Gas furnace, main burner ignites the other 2 don't. then shutdn.


Between the burners is a small rail in the pressed steel where the flame runs across to light the other burners and it sounds like there is dirt or debris in the step over rails causing the problem. You will need to use some compressed air on those rails to clear them out. Once the rails are clear the other two burners should ignite right away.

What kind of ignition is it? If it is a Hot surface igniter(glow coil) look for a small, maybe 3-4 inch long rod that is mounted to or near the burner. It's probably on the burner on the side away from the igniter and would be in the flame when the burner comes on. Clean it with sand paper. It's a flame sensor and the igniter is sending a small amount of voltage through the flame(fire is a conductor) to the sensor and if it's dirty it won't complete the circuit. If after cleaning it works then great you need to get a new one within a few days. If it doesn't work then the igniter is probably weak and needs replacing but it could be something else so I would call for service instead of guessing.

Carrier furnace weathermaker 8000


. Several times of recyling power normally brings the furnance up. Though the failure code has always been 31, there are several different behaviour when the blower starts after reset :
a. blower simply creases.
b. there is an attempt to start the heating unit (I hear the high pitch noises), then everything stops.
c. there is an attempt to start the heating unit (I hear the high pitch noises), once I see the orange glow from the coil, normally the gas is lit up and the unit starts working.

Honeywell Gas Furnace


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.
