How a Low-Fire Pressure Switch Works
Two-stage furnaces have various pressure switches to allow the system to run at different speeds—and use less energy. These switches also make sure your furnace runs safely and vents extraneous gases from the heat exchanger.
What Happens When a Low-Fire Pressure Switch Doesn’t Work
Your low pressure switch may not be operating properly if your furnace inducer motor begins in high speed and high ignition, then loses speed and shifts into low-fire mode about 30 seconds later.
Your HVAC will indicates something’s not right 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 tells you a fault code.
