How a Pressure Switch Works

This part plays an important duty as your furnace prepares to warm 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 moves 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 provides heat.

What Happens When a Pressure Switch Fails

When your pressure switch isn’t functioning promptly, 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 let you know something is incorrect 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 transmits a fault code.

Estimated Repair Cost for Furnace Error Code 228

Before replacing the switch, your Broad Ripple Service Experts Heating & Air Conditioning tech will investigate other parts of your furnace first. Several other issues can also cause the error code, like a blocked vent or cracked hose.

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

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