How a Low-Fire Pressure Switch Works

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

What Happens When a Low-Fire Pressure Switch Malfunctions

Your low pressure switch may not be operating right if your furnace inducer motor begins in high speed and high ignition, then slows down and changes into low-fire mode about 30 seconds later.

Your HVAC will demonstrate something’s not right with a red flash from its indicator light, which it uses to display 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 announces a fault code.
