How a Low-Fire Pressure Switch Works

Two-stage furnaces have multiple pressure switches to let the system to run at different speeds—and work more efficiently. These switches also guarantee your furnace runs safely and vents excess gases from the heat exchanger.

What Happens When a Low-Fire Pressure Switch Fails

Your low pressure switch may not be functioning properly if your furnace inducer motor switches on in high speed and high ignition, then loses speed and shifts into low-fire mode about 30 seconds afterward.

Your furnace will demonstrate something’s amiss with a red flash from its indicator light, which it uses to display error codes. It has this red light to flash code, like Morse code.

You may see fast flashes or an alternating slow flash as it reports a fault code.
