How a Pressure Switch Works

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

Here’s what occurs 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 commands 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 functioning correctly, you’ll likely hear the fan going 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 for your safety.

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