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 Doesn’t Work

Your low pressure switch may not be functioning correctly if your furnace inducer motor starts up in high speed and high ignition, then loses speed and enters into low-fire mode about 30 seconds later.

Your furnace will communicate something’s not right 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 notice fast flashes or an alternating slow flash as it reports a fault code.
