How a Low-Fire Pressure Switch Works

Two-stage furnaces have numerous pressure switches to help the system to run at different speeds—and use less energy. These switches also guarantee your furnace runs safely and vents extraneous gases from the heat exchanger.

What Happens When a Low-Fire Pressure Switch Fails

Your low pressure switch may not be functioning properly if your furnace inducer motor starts up in high speed and high ignition, then slows down and changes into low-fire mode about 30 seconds afterward.

Your system 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 observe fast flashes or an alternating slow flash as it tells you a fault code.
