How a Pressure Switch Works
This part plays an important role as your furnace prepares to heat your house.
Here’s what happens after your thermostat’s call for heat:
- Your furnace’s control board commences running the draft inducer blower motor. This drains 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 tells 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 correctly, you’ll likely hear the fan start and the switch clicking a couple 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 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 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 Wesley Wood Service Experts technician will check other parts of your furnace first. A handful of other issues can also cause the error code, like a clogged 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 plan to pay between $40 to $350.
