How a Pressure Switch Works
This part plays an important role as your furnace prepares to heat your home.
Here’s what goes on after your thermostat’s call for heat:
- Your furnace’s control board commences 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 tells 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 promptly, you’ll likely hear the fan run and the switch clicking multiple times before the furnace turns off completely. When a part isn’t functioning right, your furnace will turn off to protect you.
Your furnace will show you something is wrong 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 see quick flashes or an alternating slow flash as it transmits a fault code.
