How a Pressure Switch Works
This part plays a prominent part as your furnace prepares to heat your house.
Here’s what goes on after your thermostat’s call for heat:
- Your furnace’s control board starts running the draft inducer blower motor. This exhausts combustion gases from the heat exchanger and pulls in new gas and air so the burners can fire.
- When the pressure switch senses that sufficient air is being pulled into the burners, it closes and commands the control board to ignite the furnace.
- Your furnace ignites and creates heat.
What Happens When a Pressure Switch Malfunctions
When your pressure switch isn’t functioning the way it should, you’ll likely hear the fan start and the switch clicking a couple 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 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 notice fast flashes or an alternating slow flash as it communicates a fault code.
