How a Pressure Switch Works
This part plays an important part as your furnace prepares to warm your space.
Here’s what happens after your thermostat’s call for heat:
- Your furnace’s control board starts running the draft inducer blower motor. This exhausts 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 Malfunctions
When your pressure switch isn’t functioning the way it should, you’ll likely hear the fan run and the switch clicking a couple times before the furnace switches off completely. When a part isn’t performing right, your furnace will turn off for your safety.
Your furnace will let you know 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 see fast 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 D.A. Bennett Service Experts Expert will investigate other parts of your furnace first. Some other issues can also generate the error code, like a blocked vent or cracked hose.
The bill to fix 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 expect to pay between $40 to $350.
