How a Low-Fire Pressure Switch Works
Two-stage furnaces have various pressure switches to allow the system to run at different speeds—and use less energy. These switches also ensure your furnace runs safely and vents extra gases from the heat exchanger.
What Happens When a Low-Fire Pressure Switch Fails
Your low pressure switch may not be working properly if your furnace inducer motor switches on in high speed and high ignition, then loses speed and changes into low-fire mode about 30 seconds after.
Your HVAC will demonstrate something’s not right 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 notice 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 technician will investigate other parts of your furnace first.
The price to fix your furnace depends on what’s wrong with it and how long it takes to repair it.
You can expect to pay between $40 and $350 if you need a new low-fire pressure switch.
