How a Low-Fire Pressure Switch Works

Two-stage furnaces have various pressure switches to allow the system to run at different speeds—and work more efficiently. 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 Malfunctions

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 shifts 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 display 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 create the error, so your Stark Services Expert will look at other parts of your furnace first.

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

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