How a Pressure Switch Works
This part plays a prominent role as your furnace prepares to work in your house.
Here’s what happens after your thermostat’s call for heat:
- Your furnace’s control board commences running the draft inducer blower motor. This pushes out combustion gases from the heat exchanger and pulls 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 tells the control board to ignite the furnace.
- Your furnace ignites and provides heat.
What Happens When a Pressure Switch Fails
When your pressure switch isn’t operating the way it should, you’ll likely hear the fan going and the switch clicking a couple times before the furnace shuts down 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 display error codes. It uses this red light to flash code, like Morse code.
You may see fast flashes or an alternating slow flash as it passes on a fault code.
