How a Pressure Switch Works

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

Here’s what happens after your thermostat’s call for heat:

  • Your furnace’s control board commences running the draft inducer blower motor. This pushes out combustion gases from the heat exchanger and moves 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 supplies 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 start and the switch clicking multiple times before the furnace shuts down completely. When a part isn’t performing right, your furnace will turn off to protect you.

Your furnace will show 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 short flashes or an alternating slow flash as it transmits a fault code.

Estimated Repair Cost for Furnace Error Code 228

Before replacing the switch, your Service Experts Heating & Air Conditioning  tech will investigate other parts of your furnace first. Some other issues can also cause the error code, like a blocked vent or cracked hose.
