How a Low-Fire Pressure Switch Works

Two-stage furnaces have various pressure switches to help the system to run at different speeds—and use less energy. These switches also ensure your furnace runs safely and vents extra gases from the heat exchanger.

What Happens When a Low-Fire Pressure Switch Doesn’t Work

Your low pressure switch may not be working right if your furnace inducer motor starts up in high speed and high ignition, then loses speed and enters into low-fire mode about 30 seconds after.

Your furnace will communicate something’s not right 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 notice fast flashes or an alternating slow flash as it reports a fault code.

A blocked vent or a draft can also generate the error, so your Epperson Service Experts professional will investigate other parts of your furnace first.

The price 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 have to have a new low-fire pressure switch.
