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 begins running the draft inducer blower motor. This exhausts combustion gases from the heat exchanger and brings 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 signals 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 operating the way it should, you’ll likely hear the fan going and the switch clicking multiple times before the furnace switches off completely. When a part isn’t performing right, your furnace will turn off to protect you.

Your furnace will tell 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 short 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 Strand Brothers 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 price to repair 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.
