How a Pressure Switch Works

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

Here’s what happens 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 sufficient 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 correctly, you’ll likely hear the fan going and the switch clicking a few 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 tell you 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 quick flashes or an alternating slow flash as it transmits a fault code.
