For the past couple of winters, my furnace goes through a period of stopping, particularly during the coldest days of the season. The service technician replaced the logic board during one of his visits, but that did not stop the problem. I checked the fresh air intake, and there was nothing blocking it. However, the furnace would start when I disconnected it as it pulled air from my two-car garage where the furnace is located. When the weather improved, the furnace would run without any problem. Is this a sign that my 13 year old high-efficiency furnace needs to be replaced, or is there something about my furnace that cannot deal with very cold air? Thanks.
