How a Low-Fire Pressure Switch Works
Two-stage furnaces have numerous 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 Doesn’t Work
Your low pressure switch may not be operating properly if your furnace inducer motor switches on in high speed and high ignition, then slows down and shifts into low-fire mode about 30 seconds afterward.
Your system will demonstrate something’s wrong with a red flash from its indicator light, which it uses to display 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 tells you a fault code.
Estimated Repair Cost for Furnace Error Code 229
A blocked vent or a draft can also create the error, so your Service Experts Heating & Air Conditioning Expert will check other parts of your furnace first.
