How a Pressure Switch Works

This part plays an important role as your furnace prepares to heat your space.

Here’s what happens 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 pulls 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 signals the control board to ignite the furnace.
  • Your furnace ignites and supplies heat.

What Happens When a Pressure Switch Malfunctions

When your pressure switch isn’t operating correctly, you’ll likely hear the fan run and the switch clicking a few 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 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 see short 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 BW/Cook Service Experts  tech will check 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 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.
