How a Pressure Switch Works

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

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 pulls 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 tells 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 functioning the way it should, you’ll likely hear the fan going and the switch clicking a couple times before the furnace switches 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 present error codes. It uses this red light to flash code, like Morse code.

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