How a Low-Fire Pressure Switch Works
Two-stage furnaces have various pressure switches to allow the system to run at different speeds—and work more efficiently. These switches also guarantee your furnace runs safely and vents excess gases from the heat exchanger.
What Happens When a Low-Fire Pressure Switch Fails
Your low pressure switch may not be working correctly 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 furnace will indicates 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 see fast flashes or an alternating slow flash as it reports a fault code.
