How a Low-Fire Pressure Switch Works

Two-stage furnaces have numerous 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 extraneous 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 weakens and shifts into low-fire mode about 30 seconds later.

Your furnace will demonstrate something’s not right 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 notice 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 create the error, so your Roland J. Down Service Experts technician will investigate other parts of your furnace first.

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

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