How a Low-Fire Pressure Switch Works
Two-stage furnaces have numerous pressure switches to help the system to run at different speeds—and work more efficiently. These switches also ensure your furnace runs safely and vents excess 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 starts up in high speed and high ignition, then slows down and changes into low-fire mode about 30 seconds after.
Your HVAC 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 observe 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 create the error, so your Coastal Service Experts Expert will investigate other parts of your furnace first.
The price to fix your furnace relies 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 need a new low-fire pressure switch.
