How a Pressure Switch Works

This part plays a critical role 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 drains combustion gases from the heat exchanger and moves in new gas and air so the burners can fire.
  • When the pressure switch senses that plenty of 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 working the way it should, 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 to protect you.

Your furnace will let you know something is incorrect 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 see fast flashes or an alternating slow flash as it transmits a fault code.
