How a Low-Fire Pressure Switch Works

Two-stage furnaces have multiple pressure switches to help the system to run at different speeds—and use less energy. These switches also make sure your furnace runs safely and vents excess gases from the heat exchanger.

What Happens When a Low-Fire Pressure Switch Malfunctions

Your low pressure switch may not be working properly if your furnace inducer motor switches on in high speed and high ignition, then slows down and changes into low-fire mode about 30 seconds later.

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

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