How a Low-Fire Pressure Switch Works
Two-stage furnaces have multiple pressure switches to help the system to run at different speeds—and work more efficiently. 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 operating 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 furnace will communicate something’s wrong 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.
Estimated Repair Cost for Furnace Error Code 229
A blocked vent or a draft can also create the error, so your McElroy Service Experts professional will look at other parts of your furnace first.
