How a Pressure Switch Works

This part plays a prominent duty 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 starts running the draft inducer blower motor. This pushes out 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 signals 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 promptly, you’ll likely hear the fan start and the switch clicking a couple times before the furnace shuts down completely. When a part isn’t working right, your furnace will turn off for your safety.

Your furnace will let you know 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 short flashes or an alternating slow flash as it passes on a fault code.
