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 starts running the draft inducer blower motor. This drains 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 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 operating correctly, you’ll likely hear the fan run 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 to protect you.

Your furnace will tell you 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 see quick 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 Comfortech Service Experts Heating & Air Conditioning tech will check other parts of your furnace first. A handful of other issues can also generate the error code, like a clogged vent or cracked hose.

The cost 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.
