How a Pressure Switch Works

This part plays an important role as your furnace prepares to work in 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 pulls 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 provides heat.

What Happens When a Pressure Switch Malfunctions

When your pressure switch isn’t working the way it should, you’ll likely hear the fan start and the switch clicking multiple times before the furnace shuts down completely. When a part isn’t performing right, your furnace will turn off for your safety.

Your furnace will let you know 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 note short flashes or an alternating slow flash as it passes on a fault code.
