Mine was my thermostat. The power splitter for the ecobee got wet and for some reason everything would run but their was no fire. Removed the power splitter and everything worked fine
There inside the combustion chamber is a steel rod very thin that is screwed on from top it gets coated with dust and it stops furnace from staying on clean out all of furnace put a little machine oil after cleaning out this will make dust stick to metal frame But I’ve cleaned this rod happens if you don’t clean furnace every year
+Chad Colston I pulled the igniter and cleaned it. That seemed to do something but it only worked intermittently. I suspected a control board problem. Ended up changing my programmable thermostat (I was using a HydroOne Peaksaver) and I switched back to my more basic programmable Honeywell model. I haven't had a problem since. So I'm not 100% sure of the fix but it's working now for me
@@Sixslo-47799 I had to replace the motherboard. It was like 88$ thru Amazon. I bet I had a power surge or something. I first thought maybe the thermostat but that was good.

Chad Colston you need to change your pressure switch. Round black thing with tubes and wires connected. Apparently very common on Armstrong’s.
This was not helpful at all
what did you do to fix yours?
