How a Pressure Switch Works

This part plays a critical duty as your furnace prepares to work in your house.

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

  • Your furnace’s control board starts running the draft inducer blower motor. This exhausts combustion gases from the heat exchanger and pulls 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 supplies 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 run and the switch clicking a couple times before the furnace shuts down completely. When a part isn’t performing right, your furnace will turn off as a safety precaution.

Your furnace will let you know something is amiss with a red flash from its indicator light, which it uses to exhibit 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.
