How a Pressure Switch Works
This part plays a critical part as your furnace prepares to heat your house.
Here’s what occurs after your thermostat’s call for heat:
- Your furnace’s control board begins running the draft inducer blower motor. This exhausts 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 Malfunctions
When your pressure switch isn’t functioning the way it should, you’ll likely hear the fan going and the switch clicking multiple 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 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 transmits a fault code.
Estimated Repair Cost for Furnace Error Code 228
Before replacing the switch, your Service Experts Heating & Air Conditioning 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 bill to repair 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 plan to pay between $40 to $350.
