How a Pressure Switch Works

This part plays a critical part as your furnace prepares to warm your space.

Here’s what goes on after your thermostat’s call for heat:

  • Your furnace’s control board begins 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 commands the control board to ignite the furnace.
  • Your furnace ignites and creates heat.

What Happens When a Pressure Switch Fails

When your pressure switch isn’t functioning correctly, you’ll likely hear the fan run and the switch clicking multiple times before the furnace shuts down completely. When a part isn’t working right, your furnace will turn off as a safety precaution.

Your furnace will show you 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 quick flashes or an alternating slow flash as it passes on a fault code.
