How a Pressure Switch Works

This part plays a prominent part as your furnace prepares to heat your house.

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 pulls in new gas and air so the burners can fire.
  • When the pressure switch senses that sufficient 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 functioning the way it should, you’ll likely hear the fan start and the switch clicking a couple times before the furnace shuts down completely. When a part isn’t performing right, your furnace will turn off as a safety precaution.

Your furnace will let you know 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 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 Stallion Heating and Air Conditioning  tech will investigate other parts of your furnace first. A handful of other issues can also create the error code, like a congested vent or cracked hose.

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