How a Pressure Switch Works

This part plays a critical part as your furnace prepares to warm your space.

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

  • Your furnace’s control board begins running the draft inducer blower motor. This pushes out combustion gases from the heat exchanger and moves in new gas and air so the burners can fire.
  • When the pressure switch senses that sufficient air is being pulled into the burners, it closes and commands 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 correctly, you’ll likely hear the fan run 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 to protect you.

Your furnace will show you something is wrong 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 see quick flashes or an alternating slow flash as it communicates a fault code.
