How a Low-Fire Pressure Switch Works

Two-stage furnaces have multiple pressure switches to help the system to run at different speeds—and work more efficiently. These switches also guarantee 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 correctly if your furnace inducer motor starts up in high speed and high ignition, then loses speed and changes into low-fire mode about 30 seconds later.

Your HVAC will indicates something’s not right with a red flash from its indicator light, which it uses to show error codes. It has this red light to flash code, like Morse code.

You may see 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 Commercial HVAC Expert will look at other parts of your furnace first.

The bill to fix your furnace hinges on what’s wrong with it and how long it takes to remedy it.
