How a Low-Fire Pressure Switch Works
Two-stage furnaces have numerous 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 extraneous 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 starts up in high speed and high ignition, then loses speed and changes 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 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 trigger the error, so your Peachtree Service Experts technician will check other parts of your furnace first.
The cost to fix your furnace depends 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 need a new low-fire pressure switch.
