How a Low-Fire Pressure Switch Works
Two-stage furnaces have multiple pressure switches to allow the system to run at different speeds—and use less energy. These switches also make sure 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 begins in high speed and high ignition, then weakens and shifts into low-fire mode about 30 seconds after.
Your furnace 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 notice 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 A1 Chesney Service Experts professional will check 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 plan to pay between $40 and $350 if you have to have a new low-fire pressure switch.
