How a Low-Fire Pressure Switch Works

Two-stage furnaces have numerous 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 extra gases from the heat exchanger.

What Happens When a Low-Fire Pressure Switch Fails

Your low pressure switch may not be functioning correctly if your furnace inducer motor switches on in high speed and high ignition, then weakens and enters into low-fire mode about 30 seconds later.

Your furnace will indicates 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 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 Norrell Service Experts Expert will check other parts of your furnace first.

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

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