How a Pressure Switch Works

This part plays an important role as your furnace prepares to work in your space.

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 sufficient 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 start and the switch clicking a couple times before the furnace shuts down completely. When a part isn’t working right, your furnace will turn off to protect you.

Your furnace will tell 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 fast flashes or an alternating slow flash as it transmits a fault code.
