If it's just a standard bed burner atmospheric type only there are some real problems might be. 1st as has been suggested that it might be the fan motor. 2 could be the end of career fan. There is an active temperature switch that brings the fan when the temperature warms the heart. This switch also turns off the fan once the heart is cooled. Some units have individual fans and limits, some have combination. There is another temperature activated switch should close the burner (upper limit) if the temperature reaches the highest in the plenary. If your furnace has air conditioning, so you can quickly check the fan simply by switching the air conditioner of the position. If the fan starts and runs the problem is in the final race. If you do not have air conditioning that also have a fan relay. The relay is powered by a 24v signal and 110v to fan motor transfers.
