How a Pressure Switch Works

This part plays an important role as your furnace prepares to work in your house.

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 enough air is being pulled into the burners, it closes and tells 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 operating the way it should, you’ll likely hear the fan start and the switch clicking a couple 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 tell you something is wrong 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 see quick flashes or an alternating slow flash as it communicates a fault code.

Before replacing the switch, your Orangutan Home Services Expert will investigate other parts of your furnace first. A handful of other issues can also generate the error code, like a congested vent or cracked hose.

The cost to repair your furnace depends on what’s wrong with it and how long it takes to fix it.
