How a Pressure Switch Works

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

Here’s what goes on 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 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 provides heat.

What Happens When a Pressure Switch Breaks Down

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

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

You may see fast 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  Expert will investigate other parts of your furnace first. A handful of other issues can also create the error code, like a blocked vent or cracked hose.

The bill to remedy your furnace depends on what’s defective with it and how long it takes to fix it.
