How a Pressure Switch Works
This part plays a critical duty as your furnace prepares to heat your home.
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 moves 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 commands 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 multiple times before the furnace shuts down completely. When a part isn’t working right, your furnace will turn off for your safety.
Your furnace will tell you something is amiss 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 short flashes or an alternating slow flash as it communicates a fault code.
