Most likely your flame rod is either dirty, bad or the flame is not hitting it. It is located either to the far left or far right of the burner box. It has one wire going to it and looks like a small stick pointing into the flame. Clean it with a long tooth brush. Inspect the wire where it attaches to both the rod and the control module. Inspect the flame as it starts and see if the flame reaches it within 2 to 3 seconds from first flame. If not, you may have debris clogging the flame tray not allowing the flame to pass. If this is beyond your mechanical skills (no offence) contact your gas technician.

If the pilot go out on a furnace would gas continue to flow to the pilot , or would it shut off with in a few seconds


The pilot flame heats a thermocouple, so if the pilot goes out, the thermocouple cools and shuts off the gas. It can take anywhere from 20 seconds to 2 minutes for it to shut off. You should hear an audible click when it happens.

Hi~ i have a coleman-evcon heater in a mobile. The heater comes on when the thermosat is turned up to, say 65 from 55, then before the air blown out is even really warm, it shuts off. it runs on propane,...


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).

Heater will fire but wont stay lit.


I assume that you are referring to a natural gas forced air furnace. If so you just described the symptoms of a dirty flame sensor. Remove the sensor with a 1/4" nutdriver. clean the flame sensor with a small piece of fine grit sandpaper or emery cloth. replace the sensor and turn the furnace back on.
Good luck.....

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.

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 :)

Coleman direct vent forced air furnace


I am a furnace technician and to solve the problem.You will find on the opposite side of the ignitor their is a flame rod with a wire connected to it.Remove it and clean it with sandpaper and re install it and it should fix the problem.If this is dirty it won't sense ignition and the board thinks that is it introducing raw gas into furnace and it isn't igniting and shuts off as a safety precaution.If you see a blueish tinge on the flame rod you should probably replace it.
