How a Pressure Switch Works

This part plays a prominent role as your furnace prepares to work in your home.

Here’s what happens 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 Breaks Down

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

Your furnace will tell you something is wrong with a red flash from its indicator light, which it uses to exhibit 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 passes on a fault code.
