How a Pressure Switch Works

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

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

  • Your furnace’s control board begins running the draft inducer blower motor. This pushes out combustion gases from the heat exchanger and brings 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 operating 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 working right, your furnace will turn off as a safety precaution.

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 note short flashes or an alternating slow flash as it passes on a fault code.
