How a Pressure Switch Works
This part plays a prominent 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 begins running the draft inducer blower motor. This exhausts combustion gases from the heat exchanger and brings 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 signals the control board to ignite the furnace.
- Your furnace ignites and creates heat.
What Happens When a Pressure Switch Malfunctions
When your pressure switch isn’t operating the way it should, you’ll likely hear the fan going 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 as a safety precaution.
Your furnace will tell you something is incorrect 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 quick flashes or an alternating slow flash as it passes on a fault code.

Before replacing the switch, your Stallion Heating and Air Conditioning Expert will check other parts of your furnace first. Some other issues can also cause the error code, like a clogged vent or cracked hose.
The bill to remedy your furnace depends on what’s wrong with it and how long it takes to fix it.
