How a Low-Fire Pressure Switch Works
Two-stage furnaces have various pressure switches to help the system to run at different speeds—and use less energy. These switches also ensure your furnace runs safely and vents extra gases from the heat exchanger.
What Happens When a Low-Fire Pressure Switch Fails
Your low pressure switch may not be functioning properly if your furnace inducer motor switches on in high speed and high ignition, then loses speed and changes into low-fire mode about 30 seconds later.
Your system will communicate something’s amiss 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.

A blocked vent or a draft can also trigger the error, so your Service Experts Heating & Air Conditioning technician will look at other parts of your furnace first.
