How a Pressure Switch Works

This part plays a prominent part as your furnace prepares to heat your house.

Here’s what happens after your thermostat’s call for heat:

  • Your furnace’s control board commences running the draft inducer blower motor. This pushes out combustion gases from the heat exchanger and brings in new gas and air so the burners can fire.
  • When the pressure switch senses that enough air is being pulled into the burners, it closes and tells the control board to ignite the furnace.
  • Your furnace ignites and creates heat.

What Happens When a Pressure Switch Breaks Down

When your pressure switch isn’t functioning promptly, you’ll likely hear the fan going and the switch clicking multiple times before the furnace turns off completely. When a part isn’t functioning right, your furnace will turn off as a safety precaution.

Your furnace will show you something is incorrect with a red flash from its indicator light, which it uses to display error codes. It uses this red light to flash code, like Morse code.

You may notice quick flashes or an alternating slow flash as it communicates a fault code.
