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 commences running the draft inducer blower motor. This drains combustion gases from the heat exchanger and pulls in new gas and air so the burners can fire.
  • When the pressure switch senses that enough 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 the way it should, you’ll likely hear the fan run 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 as a safety precaution.

Your furnace will tell you 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 fast flashes or an alternating slow flash as it passes on a fault code.
