How a Pressure Switch Works

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

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 signals 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 working promptly, you’ll likely hear the fan start and the switch clicking a few times before the furnace shuts down completely. When a part isn’t functioning right, your furnace will turn off as a safety precaution.

Your furnace will let you know 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 note quick flashes or an alternating slow flash as it communicates a fault code.

Estimated Repair Cost for Furnace Error Code 228

Before replacing the switch, your Stevenson Service Experts  technician will look at 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 fix your furnace depends on the issue with it and how long it takes to fix it.

If your pressure switch needs to be replaced, you can plan to pay between $40 to $350.
