How a Pressure Switch Works
This part plays a critical duty 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 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 provides heat.
What Happens When a Pressure Switch Breaks Down
When your pressure switch isn’t working promptly, you’ll likely hear the fan run and the switch clicking a few times before the furnace turns off completely. When a part isn’t functioning right, your furnace will turn off to protect you.
Your furnace will let you know something is incorrect 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 transmits a fault code.
Estimated Repair Cost for Furnace Error Code 228
Before replacing the switch, your Peitz Service Experts Expert will investigate other parts of your furnace first. A handful of other issues can also create the error code, like a congested vent or cracked hose.
The cost 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.
