How a Pressure Switch Works
This part plays a prominent duty as your furnace prepares to heat your home.
Here’s what occurs after your thermostat’s call for heat:
- Your furnace’s control board begins 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 plenty of air is being pulled into the burners, it closes and signals 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 working 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 functioning 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 notice quick flashes or an alternating slow flash as it communicates a fault code.
