How a Low-Fire Pressure Switch Works

Two-stage furnaces have various pressure switches to help the system to run at different speeds—and be more efficient. These switches also guarantee 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 correctly if your furnace inducer motor begins in high speed and high ignition, then loses speed and enters into low-fire mode about 30 seconds later.

Your furnace will indicates something’s amiss 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.

A blocked vent or a draft can also trigger the error, so your Service Experts Heating & Air Conditioning technician will check 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 fix it.

You can plan to pay between $40 and $350 if you have to have a new low-fire pressure switch.
