How a Pressure Switch Works
This part plays an important part as your furnace prepares to work in your house.
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 tells the control board to ignite the furnace.
- Your furnace ignites and provides heat.
What Happens When a Pressure Switch Fails
When your pressure switch isn’t functioning the way it should, 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 performing 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 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 transmits 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. Several other issues can also create the error code, like a congested vent or cracked hose.
The price 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.
