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 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 working right 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 HVAC will indicates something’s not right 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.
