How a Low-Fire Pressure Switch Works
Two-stage furnaces have multiple pressure switches to allow the system to run at different speeds—and work more efficiently. These switches also guarantee 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 operating correctly if your furnace inducer motor starts up in high speed and high ignition, then slows down and shifts into low-fire mode about 30 seconds afterward.
Your furnace will demonstrate something’s wrong with a red flash from its indicator light, which it uses to display error codes. It has this red light to flash code, like Morse code.
You may see 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 generate the error, so your Comfort Masters Service Experts technician will check 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 repair it.
You can expect to pay between $40 and $350 if you require a new low-fire pressure switch.
