How a Pressure Switch Works
This part plays a critical part as your furnace prepares to heat 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 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 promptly, you’ll likely hear the fan start and the switch clicking a few times before the furnace turns off completely. When a part isn’t performing right, your furnace will turn off to protect you.
Your furnace will tell you something is incorrect 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 note fast flashes or an alternating slow flash as it communicates a fault code.

Before replacing the switch, your Stevenson Service Experts tech will check other parts of your furnace first. A handful of other issues can also generate the error code, like a congested vent or cracked hose.
The bill to repair 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.
