How a Low-Fire Pressure Switch Works

Two-stage furnaces have multiple pressure switches to help the system to run at different speeds—and be more efficient. 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 operating correctly 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 afterward.

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 notice fast flashes or an alternating slow flash as it reports a fault code.

Estimated Repair Cost for Furnace Error Code 229

A blocked vent or a draft can also generate the error, so your Stevenson Service Expertsprofessional will check other parts of your furnace first.

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

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