How a Low-Fire Pressure Switch Works
Two-stage furnaces have multiple pressure switches to allow the system to run at different speeds—and be more efficient. 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 functioning properly if your furnace inducer motor switches on in high speed and high ignition, then weakens and shifts into low-fire mode about 30 seconds after.
Your system 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 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 McKinley Heating Service Experts technician will look at other parts of your furnace first.
The price to fix your furnace hinges on what’s wrong with it and how long it takes to remedy it.
You can expect to pay between $40 and $350 if you have to have a new low-fire pressure switch.
