How a Pressure Switch Works
This part plays an important role as your furnace prepares to work in your space.
Here’s what goes on 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 plenty of 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 working correctly, you’ll likely hear the fan going and the switch clicking a couple times before the furnace shuts down completely. When a part isn’t working right, your furnace will turn off to protect you.
Your furnace will let you know something is wrong with a red flash from its indicator light, which it uses to exhibit error codes. It uses this red light to flash code, like Morse code.
You may note quick 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 Donelson Air Service Experts tech will look at other parts of your furnace first. Several other issues can also cause the error code, like a congested vent or cracked hose.
The price to remedy 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 expect to pay between $40 to $350.
