SOURCE: Coleman furnace -- fan runs, ingniter won't light,

Hi,
The chances are that the furnace was running when the power went out. This will cause the high limit switch to cutout and needs to be manually reset.
You will find that switch in the blower compartment near the blower. Usually somewher near the highest point of the cabinet.
Push the little red button firmly till it clicks.
When the power goes out while the furnace is running the heat builds up because the blower shuts down immediately and causes this limit switch to cut out.
If you have a electric tester you can also follow the low voltage circuit till you find the open switch. Ther is usually a wiring schematic on the door cover of most furnaces.

I hope that this will help you to solve your problem!

Thanks for using Fixya!!

My furnace did not have a reset switch on that particular limiter. I unpugged the switch, it had 2 wires, waited 15 seconds or so and then plugged it back in . Turned the furnace back on and the limiter reset itself.

This furnace should have a diagnostic light that will give you a starting point where to look. It is located on the control board and will blink a code. If you remove the panel with the door switch on it, you will erase the code. Look for a small viewing port that looks on to the circuit board. Once you get the code, look on the wiring diagram for a explaination of the codes.

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).

Is this a blend air system? If so, there is an upper & lower control board that communicate to each other, and if the exhaust fan on the roof is out, it will give you intermittent issues. The fan mixes or blends outside air with the return of the air handler, & duals to pressurize the attic. These were installed due to mobile homes built too air tight. Without this fan, your roofing shingles will curl, and your roof decking will bow prematurely.

Solid red typically means bad controller. Try unplugging the furnace, wait about 30 secs, then plug it back in. The possibility that the controller was sending voltage to the valve even when there was no flame is a bad sign. If the controller starts the furnace, watch it very closely and see what it does. If the solid light comes back on, it's time for a new board.

Coleman mobile home furnace...Model number DGAA077BDTB...The furnace about a month ago started going out ( flash code- Combustion Air switch stuck closed)We replaced the thermostat on the wall and it...


I had the same errror code on my coleman furnace (3 flashes combustion air switch failed to close) but at first didnt realize there was even a light that gave codes..Anyways long story short, after searching many forums one guy mentioned about the furnace giving a false reading and talked about improper air flow ( coming in and going out) which isnt triggering the switch correctly. After thinking about it and after getting the furnace to run correctly every time I took the door off to tap on the switch (and other spots not knowing what the problem was yet) I always put the door right back on then the furnace would do the same thing (stop running). so I pulled the door off again got the furnace to work properly and left the door off and tested it. It ran great, it started and stopped like normal for a hour and realized I might not be getting proper air flow. Then I remembered I asked my roommate to change my filters for me while I was gone (which he did) and looked at them while I still had the door off and realized the filters were in backwards! which resticted the air flow so much the switch wouldnt operate fully. so check your air filters, something so stupid almost cost me a house visit by the furnace guy....this may not be everyones problem but maybe I will help someone save a house visit....I still cant believe that was my problem and the furnace is still running great.
