How a Low-Fire Pressure Switch Works

Two-stage furnaces have various pressure switches to help the system to run at different speeds—and be more efficient. These switches also guarantee your furnace runs safely and vents excess 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 starts up in high speed and high ignition, then slows down and changes into low-fire mode about 30 seconds after.

Your furnace will communicate something’s not right 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 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 Roy Inch & Sons Service Experts technician will look at other parts of your furnace first.
