How a Low-Fire Pressure Switch Works

Two-stage furnaces have various pressure switches to help the system to run at different speeds—and be more efficient. These switches also make sure your furnace runs safely and vents extra gases from the heat exchanger.

What Happens When a Low-Fire Pressure Switch Doesn’t Work

Your low pressure switch may not be working properly 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 system will demonstrate something’s amiss 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 tells you a fault code.
