How a Pressure Switch Works

This part plays an important duty as your furnace prepares to work in your space.

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

  • Your furnace’s control board commences 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 signals the control board to ignite the furnace.
  • Your furnace ignites and creates heat.

What Happens When a Pressure Switch Breaks Down

When your pressure switch isn’t working correctly, 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 for your safety.

Your furnace will tell you something is amiss 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 note short 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 Winnipeg Supply Service Experts technician will investigate other parts of your furnace first. Some other issues can also generate the error code, like a blocked vent or cracked hose.

The cost to fix your furnace depends on what’s defective 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.
