How a Pressure Switch Works

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

Here’s what goes on after your thermostat’s call for heat:

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

What Happens When a Pressure Switch Breaks Down

When your pressure switch isn’t operating the way it should, you’ll likely hear the fan going and the switch clicking a couple times before the furnace turns off completely. When a part isn’t working right, your furnace will turn off as a safety precaution.

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

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