How a Low-Fire Pressure Switch Works
Two-stage furnaces have numerous pressure switches to help the system to run at different speeds—and be more efficient. These switches also ensure your furnace runs safely and vents extraneous 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 switches on in high speed and high ignition, then weakens and changes into low-fire mode about 30 seconds after.
Your furnace will demonstrate 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 notice fast flashes or an alternating slow flash as it announces a fault code.
Estimated Repair Cost for Furnace Error Code 229
A blocked vent or a draft can also generate the error, so your Rolf Griffin Service Experts Heating & Air Conditioning professional will investigate other parts of your furnace first.
The cost to fix your furnace relies 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.
