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 ensure 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 functioning properly if your furnace inducer motor starts up in high speed and high ignition, then loses speed and shifts into low-fire mode about 30 seconds later.

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