How a Pressure Switch Works

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

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

  • Your furnace’s control board begins 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 sufficient air is being pulled into the burners, it closes and signals the control board to ignite the furnace.
  • Your furnace ignites and supplies heat.

What Happens When a Pressure Switch Breaks Down

When your pressure switch isn’t operating the way it should, you’ll likely hear the fan start and the switch clicking a few times before the furnace shuts down completely. When a part isn’t working right, your furnace will turn off to protect you.

Your furnace will tell you something is amiss with a red flash from its indicator light, which it uses to present error codes. It uses this red light to flash code, like Morse code.

You may note quick flashes or an alternating slow flash as it passes on a fault code.
