How a Pressure Switch Works
This part plays an important part as your furnace prepares to heat your space.
Here’s what occurs 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 brings in new gas and air so the burners can fire.
- When the pressure switch senses that plenty of air is being pulled into the burners, it closes and commands the control board to ignite the furnace.
- Your furnace ignites and creates 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 couple times before the furnace switches off completely. When a part isn’t performing 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 note short flashes or an alternating slow flash as it passes on a fault code.

Before replacing the switch, your Service Experts Heating & Air Conditioning tech will check other parts of your furnace first. Some other issues can also create the error code, like a blocked 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 plan to pay between $40 to $350.
