How a Low-Fire Pressure Switch Works

Two-stage furnaces have various pressure switches to help the system to run at different speeds—and be more efficient. These switches also make sure your furnace runs safely and vents excess gases from the heat exchanger.

What Happens When a Low-Fire Pressure Switch Malfunctions

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

Your system will indicates something’s amiss 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 announces a fault code.

Estimated Repair Cost for Furnace Error Code 229

A blocked vent or a draft can also generate the error, so your Teays Valley Service Experts technician will check other parts of your furnace first.

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

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