How a Pressure Switch Works

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

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

  • Your furnace’s control board starts running the draft inducer blower motor. This pushes out 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 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 functioning promptly, you’ll likely hear the fan run and the switch clicking a couple times before the furnace switches 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 display error codes. It uses this red light to flash code, like Morse code.

You may note short flashes or an alternating slow flash as it passes on a fault code.
