How a Low-Fire Pressure Switch Works
Two-stage furnaces have various pressure switches to allow the system to run at different speeds—and be more efficient. These switches also make sure 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 properly if your furnace inducer motor begins in high speed and high ignition, then weakens and shifts into low-fire mode about 30 seconds later.
Your HVAC will demonstrate 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 see fast flashes or an alternating slow flash as it reports a fault code.
