SOURCE: new furnace flame rollout
Have you checked the venting either on the side of the house or on the roof ? did you or the company who installed it go by the specs on how many elbows and length of the venting run ? It also sounds like you have some blockage somewhere, if your in a climate that has alot of snow or some type of freezing rain, your intake or exhaust could be plugged by ice or snow, if so, a quick solution for this is if you have a shop vac , take the tube and hook it up to the exhaust side of the vac, then place the vac tube into the 2" vent wrap a rag around that to make a better air seal, then turn the unit on, if ice is the problem it will blow it right out ! if this does not fix the problem, I would consult the company who installed it and have them come take a look, should be no charge if the system is new, hope this advise helped, please rate this and let us know how we did, thanks for your qquestion,

Unfortunately that means there's a hole in the heat exchanger, particularly in that cell of it. When the main blower comes on the air is pushed into the heat exchanger, causing the flame rollout. A heat exchanger crack or blowout is usually what condemns a furnace for good. Goodmans however, have a lifetime warranty on their heat exchangers, so you'll probably be able to find someone to replace it pretty cheap, or do it yourself for free.
