How a Pressure Switch Works

This part plays an important part as your furnace prepares to work in your space.

Here’s what goes on 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 pulls 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 provides heat.

What Happens When a Pressure Switch Breaks Down

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 turns off completely. When a part isn’t performing right, your furnace will turn off as a safety precaution.

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