How a Pressure Switch Works

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

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

  • Your furnace’s control board begins 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 provides heat.

What Happens When a Pressure Switch Breaks Down

When your pressure switch isn’t working promptly, you’ll likely hear the fan run 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 as a safety precaution.

Your furnace will let you know something is amiss 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 quick flashes or an alternating slow flash as it passes on a fault code.

Estimated Repair Cost for Furnace Error Code 228

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

The bill to repair 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.
