Coleman Evcon no fan when in heating mode

I have a Coleman Evcon Model BFU05012AX The cold air mode works fine, But, while in heating mode I get flame only for a few seconds and the main blower does not come on and the flame goes out. It cycles through this three times and then shuts off.

    With 4 successful demand tests it worked every time after cleaning the flame proving device. I am sure that it will work tonight when it gets chilly. Thank you for your assistance.

    May God Bless you and your service.

Sounds like your flame proving device is not proving the flame. It is located on the last burner looks like a piece of thick wire sitting right beside the last burner. To Save you about 50 bucks service call take some steel wool and very gently clean the carbon that has built up on the surface of the device. Should only take 4 or 5 strokes.

Main blower will delay when in heating mode as to allow the heat chamber to build up enough heat to trigger the fan switch.

look at the furnace and turn it on to see if the flames come on. Watch and see if they stay on for a period of time. If they come on then go out you may have a dirty flame sensor, if it goes out and then relights it may be a high limit switch getting weak. hope this helps.

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 :)

I have a Coleman/Evcon Presidential ser# 074878. The plumber says the Heat exchanger is cracked. Is this something I can fix myself or is it less expenxive to buy a new furnace?


The heat exchanger is a bear to change. depending on the age of the unit it might be more practical to replace the unit. However unless you trust this service tech I'd get a second opinion, because it is rare that a heat exchanger will crack, plus by law he or she should have shut the furnace down do to carbonminoxde. Especially rare in Coleman Evcon series units.
