How a Pressure Switch Works
This part plays a prominent part as your furnace prepares to warm 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 drains 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 creates heat.
What Happens When a Pressure Switch Breaks Down
When your pressure switch isn’t operating correctly, you’ll likely hear the fan going and the switch clicking a few times before the furnace shuts down completely. When a part isn’t performing right, your furnace will turn off as a safety precaution.
Your furnace will let you know 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 notice fast flashes or an alternating slow flash as it communicates a fault code.
