Most no-heat calls in Springfield trace to one of five faults: a failed igniter, a dirty or misaligned flame sensor, a pressure switch held open by a blocked flue or condensate line, a failed blower motor or capacitor, or a control board that has locked out after repeated failed ignition attempts. Of those, the flame sensor and igniter are inexpensive parts and account for a large share of winter calls.
A furnace that lights and then shuts down after a minute or two is usually telling you about the flame sensor or about airflow. The sensor confirms to the control board that a flame is actually present, and a light carbon coating on it is enough to break that signal. Airflow-driven shutdowns come from a clogged filter or blocked returns causing the limit switch to trip on high temperature, which is the furnace protecting its own heat exchanger.
Short cycling deserves attention beyond the immediate discomfort, because repeated overheating cycles are exactly what cracks a heat exchanger over time. A cracked exchanger is a combustion gas problem, not just an efficiency one, which is why any furnace diagnosis we run includes an exchanger inspection rather than only clearing the fault code.
If the furnace is over fifteen years old and the repair involves the heat exchanger, the inducer motor, or the control board, the replacement conversation is worth having honestly. See furnace installation for what that costs, and our comparison of heat pumps and furnaces if you are weighing a change of system type.
