How a Pressure Switch Works
This part plays a critical part as your furnace prepares to work in your space.
Here’s what goes on after your thermostat’s call for heat:
- Your furnace’s control board begins 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 plenty of 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 operating the way it should, you’ll likely hear the fan going and the switch clicking multiple 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 let you know something is amiss 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 fast flashes or an alternating slow flash as it transmits a fault code.
