How a Pressure Switch Works

This part plays a prominent part as your furnace prepares to work in your space.

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

  • Your furnace’s control board starts running the draft inducer blower motor. This exhausts combustion gases from the heat exchanger and moves 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 signals the control board to ignite the furnace.
  • Your furnace ignites and creates heat.

What Happens When a Pressure Switch Breaks Down

When your pressure switch isn’t functioning promptly, you’ll likely hear the fan run and the switch clicking a couple times before the furnace turns off completely. When a part isn’t performing right, your furnace will turn off for your safety.

Your furnace will tell you something is wrong 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 notice fast flashes or an alternating slow flash as it communicates a fault code.
