How a Pressure Switch Works
This part plays a prominent role as your furnace prepares to work in your home.
Here’s what occurs 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 moves 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 signals the control board to ignite the furnace.
- Your furnace ignites and creates 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 few 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 let you know something is amiss 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 notice short 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 Becht/Givens Service Experts Expert will investigate other parts of your furnace first. A handful of other issues can also cause the error code, like a congested vent or cracked hose.
The bill 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.
