How a Pressure Switch Works

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

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

  • Your furnace’s control board commences 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 enough 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 Fails

When your pressure switch isn’t operating promptly, you’ll likely hear the fan run and the switch clicking a few times before the furnace turns off completely. When a part isn’t functioning right, your furnace will turn off for your safety.

Your furnace will let you know something is amiss 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 passes on a fault code.
