Two-stage furnaces have various pressure switches to allow the system to run at different speeds—and work more efficiently. These switches also make sure your furnace runs safely and vents extra gases from the heat exchanger.
Your low pressure switch may not be functioning right 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 later.
Your furnace will indicates something’s wrong 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 notice fast flashes or an alternating slow flash as it reports a fault code.
A blocked vent or a draft can also trigger the error, so your Falso Service Expertsprofessional will investigate 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.
