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 extraneous gases from the heat exchanger.

What Happens When a Low-Fire Pressure Switch Fails

Your low pressure switch may not be working properly if your furnace inducer motor begins in high speed and high ignition, then weakens and changes into low-fire mode about 30 seconds afterward.

Your HVAC will demonstrate something’s wrong 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 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 Midland Air Service Experts technician will investigate other parts of your furnace first.

You can expect to pay between $40 and $350 if you need a new low-fire pressure switch.
