How a Pressure Switch Works
This part plays an important duty as your furnace prepares to heat your space.
Here’s what goes on after your thermostat’s call for heat:
- Your furnace’s control board commences 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 enough air is being pulled into the burners, it closes and commands the control board to ignite the furnace.
- Your furnace ignites and supplies heat.
What Happens When a Pressure Switch Breaks Down
When your pressure switch isn’t functioning correctly, you’ll likely hear the fan start and the switch clicking a few times before the furnace shuts down completely. When a part isn’t functioning right, your furnace will turn off to protect you.
Your furnace will show 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 note 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 Service Experts Heating & Air Conditioning technician will look at other parts of your furnace first. Several other issues can also cause the error code, like a blocked vent or cracked hose.
The cost 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.
