How a Pressure Switch Works
This part plays a critical 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 pushes out combustion gases from the heat exchanger and moves 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 commands 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 operating the way it should, you’ll likely hear the fan run and the switch clicking a couple times before the furnace shuts down completely. When a part isn’t working right, your furnace will turn off as a safety precaution.
Your furnace will show you something is wrong with a red flash from its indicator light, which it uses to display error codes. It uses this red light to flash code, like Morse code.
You may notice fast flashes or an alternating slow flash as it communicates a fault code.

Before replacing the switch, your Peachtree Service Experts Expert will investigate other parts of your furnace first. Some other issues can also cause the error code, like a clogged vent or cracked hose.
The price to remedy 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.
