I have a Coleman forced air furnace that when turned on will heat up get to temp and then it blows the flame out but the fan motor continues to run. if i shut the furnace off and restart it it quickly heats up and blows hot air until temp is reached then turn off with the blower motor still running. what could it be ?

    The fan should continue blowing untill chamber is cooled down,{a safety precaution.}I would shut off power to unit for around 30min.&then turn it back on & see if it will do a normal cycle.If not look for reset button on the blower motor.

Based on the info you have given here, I am going to make some assumptions. In "cleaning out all the components" you cleaned the air filter or changed it, cleaned the duct-work, and the intake combustion chamber? When the "furnace stays lite" the pilot and the main burner stays on? Lastly, when it "continues to blow cold air" is this when the main burner is on after long periods of time? If the answers are all yes, then maybe some of the ducts have come off, or the burners aren't working correctly.

Yes, this a symptom when the heat exchanger has a crack in it. Get someone there today! If there is a crack, you could be exposing yourself to Carbon Monoxide! GET IT CHECKED NOW.

Rmove the two screws holding the blower in place and slide it out. With the power off, rotate the wheel and inspect for debris or an impingement. If everything turns easy, you have a bad motor or start capacitor. If you have rubbing, adjust the wheel. If the motor will not turn, replace it.

SOURCE: furnace blower not working how it should

first off buy yourself a honeywell stat, in my personal opinion lux stats are garbage, I have run into so many that are bad stats !!! but as far as your fan not shuting down, sounds to me like your fan center on your circuit board is bad and will not shut down the fan when needed, you will have to replace the circuit board, as the fan center is a part of the whole of the circuit board, hope that helps

Clean the flame sensor with a green scotch brite pad. Check all ground connections from the circuit board to the furnace cabinet. Check for a proper ground to the electrical box. Make sure polarity has not been reversed.

I have a coleman furnace model 4066A656


Make sure your air filter is clean. Is the thermostat satisfied? or is the room temp. still below the thermostat setting? When ever you have to turn the power off and then back on to a furnace that usually indicates that the furnaces ignition control locked out. The first thing that I would try is cleaning the flame rod.

Blower fan continually runs


It may be but the fan control may be set to turn off at to high a temp, or theres a short between ;r; and g at the stat or furnace or sequencer, IF it runs through it. A limit or rollout switch may have failed but this will keep the unit from firering. Check for a manual blower switch that may be on. At stat it should be at auto and alsso at the fan control. A stuck relay is always possible,

Coleman furnace problems


I take you mean there is a fan coming on that blows AC air thru the vents and is the same fan used to blow the heat ? If that is the case is the fan coming on when the heat comes on ? If not then that is why you are not getting the heat.
That can be from a temp sensor not working or a control board or a contactor
First see if the fan even comes on or if the same fan is used for both AC and heat

Furnace lights blows heat in cycle, pops sensor on blower and continuosly blows air until button on sensor is pushed back in


If the sensor knocks the unit off and the the fan keeps blowing without a flame ,the limit (the sensor is a limit comptroller that turns off flame @ a set temp and allows the fan to run until the heat exchanger cools to @ set temp) has out lived its lifetime and needs to be replaced.the button is a manual reset that once reset would allow the unit to continue to run flame and blower at the same time after having been set once, if it is an ongoing problem and needs to be reset more than once then replace the limit control (sensor) in kind. (With the same mode and set-points for the limits)

The furnace will light up and the fan will blow but the flames cut out before my house reaches temp. i have the thermostat set at 70 and the house will not get above 55. i have tried turning the propane...


First, for those of you who might not know, "What is a flame sensor?" A flame sensor is a safety device. When your furnace's main burners ignite (light Up) the flame sensor picks up the heat from the furnace's main burning and says, "YES," and sends a signal back to the main furnace control board saying that it is OK to let the main burner stay on. Or if the main burners do not ignite, the flame sensor does not pick up the heat and says, "NO" to the main control board, Shut That Gas Valve and Main Burners Down! Thank God we have safety controls like the flame sensor. Most of the time, after turning your furnace's power off, you may clean the flame sensors with light sand cloth, emery cloth or steel wool. Reinstall the flame sensor and you are back in business! Over the years flame sensors can build up a light coating of burned-in dust and dirt. This insulates the flame sensor so that it doesn't sense the heat of the flame well enough, so by cleaning it you have almost restored it to its new condition. Seldom, but sometimes they do go out completely.

Burner flame going out on windy days on Coleman Evcon LP furnace


This sounds like a bad heat exchanger. It is possible that you do not see the crack because the crack is closed when the heat exchanger is cold (or room temp). Allow the furnace to heat up, this will allow the expansion of the crack. Turn the power off and examine the heat exchanger while it is still hot.

I have a coleman furnace with a pilot light that keeps going out.When i manually light it the furnace runs 12 to 14 hours, then no more pilot light and i must relight.


Remove the burner and gas valve from the furnace and use compressed air to blow the area under the pilot area ans all around it. The dust and stuff usually cause a condition called "Lazy Pilot" and the flame is probably not going in the designed directions. While you have it out Id replace the thermocouple with a new one reassemble and re-lite and note the difference. The flame should be mostly Blue and no yellow (or vary little at the top end of the flame only) Orange in the top area indicates a good burning flame and the closer to the base the bluer it gets.


While you have the burner out look inside and inspect the inner heat exchanger for cracks or rusted open holes there should be none. Turn on your fan while inspecting and see if you feel the steady blow of air from it inside the heat exchanger indicating a hole. Don't confuse the air that may come down the flue with the air from the blower though. A little breeze is expected from this.

This will take care of over 90% of the problems with the "Blow out" symptom.

If you still have problems you can try and "turn up the pilot". Usually a screw close to the pilot tubing is covering the adjustment screw. Put some soap bubbles around it so you can see if it leaks or not and turn the screw out for more flame (CCW) and in (CW) for less.

Hope this helps Please grade me accordingly and good luck.

Coleman evcon dgat090bdd. New ignitor won't heat up.


Looks like 4 flashes might be high limit fault on this furnace. (I don't have a manual for this furnace, just searched online for the code meaning) Is the unit running flame at all? Is the unit running flame for a while then shutting flame off before desired temp is reached? Does the main air fan turn on to circulate air through your diffusers? Does it feel like the unit has much air flow out of the diffusers if the fan is running? Is your air filter clean? If it is infact your high limit switch, it is usually caused by not having enough airflow through the furnace and overheating occurs.

Hope this helped, let me know if I can assist you further :)
