How a Low-Fire Pressure Switch Works

Two-stage furnaces have multiple pressure switches to help 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 Malfunctions

Your low pressure switch may not be operating right if your furnace inducer motor begins in high speed and high ignition, then slows down and enters into low-fire mode about 30 seconds after.

Your HVAC will communicate something’s wrong 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 notice fast flashes or an alternating slow flash as it reports a fault code.
