How a Low-Fire Pressure Switch Works
Two-stage furnaces have multiple pressure switches to help the system to run at different speeds—and use less energy. These switches also guarantee 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 switches on in high speed and high ignition, then loses speed and shifts into low-fire mode about 30 seconds after.
Your system will indicates something’s amiss 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 observe 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 create the error, so your R & M Climate Control Service Experts Expert will check 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 fix it.
You can plan to pay between $40 and $350 if you need a new low-fire pressure switch.
