How a Low-Fire Pressure Switch Works
Two-stage furnaces have multiple pressure switches to help the system to run at different speeds—and use less energy. These switches also make sure 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 working properly if your furnace inducer motor begins in high speed and high ignition, then weakens and enters into low-fire mode about 30 seconds afterward.
Your furnace will demonstrate something’s amiss 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 tells you a fault code.
Estimated Repair Cost for Furnace Error Code 229
A blocked vent or a draft can also generate the error, so your Service Experts Heating & Air Conditioning professional will check other parts of your furnace first.
The bill 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 need a new low-fire pressure switch.
