How a Pressure Switch Works

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

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 brings 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 Malfunctions

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

Your furnace will tell you something is incorrect 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 see quick flashes or an alternating slow flash as it passes on a fault code.
