How a Pressure Switch Works

This part plays a critical role as your furnace prepares to work in your home.

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

  • Your furnace’s control board commences running the draft inducer blower motor. This exhausts combustion gases from the heat exchanger and brings 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 provides heat.

What Happens When a Pressure Switch Fails

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

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 note fast flashes or an alternating slow flash as it passes on a fault code.
