How a Pressure Switch Works

This part plays a critical role as your furnace prepares to heat your house.

Here’s what happens after your thermostat’s call for heat:

  • Your furnace’s control board starts running the draft inducer blower motor. This exhausts combustion gases from the heat exchanger and moves 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 signals 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 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 for your safety.

Your furnace will tell you something is incorrect 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 notice quick flashes or an alternating slow flash as it transmits a fault code.
