How a Low-Fire Pressure Switch Works

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

What Happens When a Low-Fire Pressure Switch Fails

Your low pressure switch may not be working right if your furnace inducer motor starts up in high speed and high ignition, then weakens and shifts into low-fire mode about 30 seconds after.

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 observe fast flashes or an alternating slow flash as it announces a fault code.
