How a Pressure Switch Works

This part plays an important duty as your furnace prepares to warm your space.

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

  • Your furnace’s control board starts 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 plenty of air is being pulled into the burners, it closes and commands the control board to ignite the furnace.
  • Your furnace ignites and creates heat.

What Happens When a Pressure Switch Malfunctions

When your pressure switch isn’t operating correctly, you’ll likely hear the fan going 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 amiss with a red flash from its indicator light, which it uses to display 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 communicates a fault code.

Estimated Repair Cost for Furnace Error Code 228

Before replacing the switch, your Falso Service Experts tech will check other parts of your furnace first. A handful of other issues can also cause the error code, like a clogged vent or cracked hose.

The bill to fix your furnace depends on what’s defective 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.
