How a Pressure Switch Works

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

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

  • Your furnace’s control board starts running the draft inducer blower motor. This drains 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 commands the control board to ignite the furnace.
  • Your furnace ignites and supplies heat.

What Happens When a Pressure Switch Fails

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

Your furnace will tell you something is amiss 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 quick flashes or an alternating slow flash as it passes on a fault code.
