How a Low-Fire Pressure Switch Works

Two-stage furnaces have multiple pressure switches to allow 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 operating right if your furnace inducer motor begins in high speed and high ignition, then weakens and changes into low-fire mode about 30 seconds afterward.

Your furnace will demonstrate something’s wrong with a red flash from its indicator light, which it uses to exhibit 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 announces a fault code.
