How a Pressure Switch Works

This part plays an important part as your furnace prepares to heat your home.

Here’s what happens 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 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 the way it should, you’ll likely hear the fan start and the switch clicking a few times before the furnace turns off completely. When a part isn’t functioning right, your furnace will turn off to protect you.

Your furnace will tell you something is amiss with a red flash from its indicator light, which it uses to display error codes. It uses this red light to flash code, like Morse code.

You may see short flashes or an alternating slow flash as it passes on a fault code.
