How a Pressure Switch Works

This part plays a prominent duty as your furnace prepares to work in 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 brings in new gas and air so the burners can fire.
  • When the pressure switch senses that sufficient 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 Malfunctions

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

Your furnace will show you something is amiss 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 fast flashes or an alternating slow flash as it communicates a fault code.
