How a Low-Fire Pressure Switch Works
Two-stage furnaces have numerous pressure switches to allow the system to run at different speeds—and be more efficient. These switches also ensure your furnace runs safely and vents extra gases from the heat exchanger.
What Happens When a Low-Fire Pressure Switch Doesn’t Work
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 afterward.
Your HVAC will communicate something’s wrong 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 observe 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 trigger the error, so your Service Experts Heating & Air Conditioning professional will check other parts of your furnace first.
