How a Low-Fire Pressure Switch Works

Two-stage furnaces have various 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 excess gases from the heat exchanger.

What Happens When a Low-Fire Pressure Switch Fails

Your low pressure switch may not be operating 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 later.

Your HVAC 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 tells you a fault code.

A blocked vent or a draft can also generate the error, so your All American Air Service Experts Expert will investigate other parts of your furnace first.
