How a Pressure Switch Works

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

Here’s what occurs 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 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 commands the control board to ignite the furnace.
  • Your furnace ignites and provides heat.

What Happens When a Pressure Switch Fails

When your pressure switch isn’t working correctly, you’ll likely hear the fan run and the switch clicking multiple times before the furnace shuts down completely. When a part isn’t working right, your furnace will turn off to protect you.

Your furnace will let you know something is incorrect with a red flash from its indicator light, which it uses to display error codes. It uses this red light to flash code, like Morse code.

You may notice short flashes or an alternating slow flash as it transmits a fault code.
