My Coleman propane furnace kicks out once and a wile and flashes a 10 flash code (gas flow with no call for heat) what need to be fixed the furnace is only 1 year old.


This sounds like you have an intermittent main board problem. It may be turning on you furnace when the thermostat is not calling for heat. It also could be a short in your low voltage(thermostat wire) going to your furnace. Either way you need to have it checked. It's under a year it should still be under warranty.

Have a Evcon Coleman Furnace shows three green blinking lights but will not ignight what could be wrong


I have had the same problem with mine for the last 2 years. Remove the motor on the side of the furnace(usually held on by 3 screws) and turn the fan blades inside by hand. after sitting all summer it seems to get stuck. If it moves freely, replace the motor and try to start it again. This fixed mine the last 2 years! Hope this helped.

Coleman furnace wont fire


Check inside the door panel next to the wiring schematic, you should find the diagnostic codes. Look up 7 blinks. This should narrow down the problem. ( It sounds like a bad hot surface ignitor).
Good luck.....

Running out of LP??


Yes. The ignitor is trying to find fire and it can't. That's an ignition error. It should go away once you get fire to the sensors. You might have to hit a reset button, it all depends on the heater.

Coleman evcon Dgato7obdc


Small blower motor? Are you talking about the combustion blower if so then check your vents for blockage.. if the vents are blocked won't work... if it has a control board init it will give you a diagnostic code. Flashing light on the board... count the flashes and look up the fault on the chart in your owners manual ot on the furnace door..

Furnace shuts off


Defective combustion air switch. The 3 blinks are an error code. You didn't say, but I'm guessing you have a Coleman Evcon. They had alot of defective Combustion air switches. Your specialists were not that.
