How a Low-Fire Pressure Switch Works
Two-stage furnaces have multiple 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 extra gases from the heat exchanger.
What Happens When a Low-Fire Pressure Switch Malfunctions
Your low pressure switch may not be working correctly if your furnace inducer motor starts up in high speed and high ignition, then loses speed and changes into low-fire mode about 30 seconds after.
Your HVAC will indicates something’s amiss 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 reports a fault code.
