How a Pressure Switch Works

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

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 brings 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 tells the control board to ignite the furnace.
  • Your furnace ignites and supplies heat.

What Happens When a Pressure Switch Breaks Down

When your pressure switch isn’t functioning correctly, you’ll likely hear the fan going and the switch clicking a couple times before the furnace switches off completely. When a part isn’t performing right, your furnace will turn off to protect you.

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