How a Low-Fire Pressure Switch Works

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

What Happens When a Low-Fire Pressure Switch Malfunctions

Your low pressure switch may not be operating properly if your furnace inducer motor begins in high speed and high ignition, then loses speed 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 exhibit 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 tells you a fault code.
