Question about Coleman Propane Forced Air Heater w/Electronic Ignition (50,000-80,000 BTU)

1 Answer

I have a Coleman furnace model number 7681-8171/b. Most everything has been replaced on this unit from the circuit board to the flame censor including the firebox which was on the recall list. The unit will sometimes work correctly but in the mornings the house temp. will only be about 60 degrees even though the Thermostat is set on 70 degrees. The flame sometimes holds and it works well but other times the flame comes on then kicks off shortly afterwards. This furnace has been nothing but problems since almost day one.

Short of being able to look at everything Its impossible to say exactly what the trouble is. Does the board have a blink code showing and a legend that says what this is? What fuel are you on NG or LP? What does the flame look like (if you can see it) IE a lot of yellow, Some orange and Blue...?. Did anyone else look at the system and the thermostat? Does it have AC or HP on it too?

The only 1 thing I may be able to offer is this. On your thermostat (if it is not electronic) there is a needle pointer that points to a number it should be around .4 to .7 if set to a lower number the thermostat will cut the unit off well before it completes a heat cycle.

Coleman dgaa furnace lights then goes out


If your talking about taking out the flame proving rod and cleaning it with sand paper or abrasive cloth and that didnt work, you may have a bad flame proving rod and it needs replaced. If the flame sensor is good, it could be the board not keeping the call to the gas valve, the gas valve not keeping the call, or your thermostat not keeping the call. Hope this helps narrow it down.

Attic fan falure hed light blinking furnace wont run


Sounds like the circuit board needs to be replaced. The exact same thing happened on my house furnace. Power went to the board, producing the flashing led, but stopped there. I believe this is what you mean?

Replace the circuit board.

Does this help? Let us know.

I have a coleman furnace it comes on the electric igniter glows red the gas comes on then the blower starts and the fire goes out it gives 2 different code for this 1 is ignition failure and the other is...


I would have the ignition control board replaced. That is what tells the gas valve to come on and if there is flame or ignition it will keep the gas on if the flame sensor gives the board a signal that the burner is lite. By you shuting power off and on to the furnace it resets the board and it will go through its cycle again.

Gas furnace; flame will not stay on


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.

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

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 :)
