How a Low-Fire Pressure Switch Works
Two-stage furnaces have numerous 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 extraneous 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 begins in high speed and high ignition, then loses speed and shifts into low-fire mode about 30 seconds afterward.
Your system will communicate something’s wrong 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 observe fast flashes or an alternating slow flash as it reports a fault code.
