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 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 changes into low-fire mode about 30 seconds after.

Your HVAC will communicate something’s wrong with a red flash from its indicator light, which it uses to show 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.
