How a Low-Fire Pressure Switch Works
Two-stage furnaces have multiple pressure switches to allow the system to run at different speeds—and use less energy. 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 Doesn’t Work
Your low pressure switch may not be functioning right if your furnace inducer motor switches on in high speed and high ignition, then weakens and enters into low-fire mode about 30 seconds later.
Your HVAC will demonstrate something’s amiss 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 notice fast flashes or an alternating slow flash as it announces a fault code.

A blocked vent or a draft can also create the error, so your Service Experts Heating & Air Conditioning professional will investigate other parts of your furnace first.
