How a Pressure Switch Works
This part plays a critical duty as your furnace prepares to work in your house.
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 drains combustion gases from the heat exchanger and pulls 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 signals 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 working correctly, you’ll likely hear the fan going and the switch clicking a few times before the furnace switches off completely. When a part isn’t functioning right, your furnace will turn off to protect you.
Your furnace will let you know 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 note fast flashes or an alternating slow flash as it transmits a fault code.
