How a Pressure Switch Works

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

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 exhausts combustion gases from the heat exchanger and brings in new gas and air so the burners can fire.
  • When the pressure switch senses that plenty of 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 Fails

When your pressure switch isn’t functioning the way it should, you’ll likely hear the fan run and the switch clicking a few 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 present 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 communicates a fault code.
