How a Pressure Switch Works
This part plays a prominent duty as your furnace prepares to warm 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 drains combustion gases from the heat exchanger and moves 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 commands the control board to ignite the furnace.
- Your furnace ignites and provides heat.
What Happens When a Pressure Switch Malfunctions
When your pressure switch isn’t working promptly, 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 working right, your furnace will turn off as a safety precaution.
Your furnace will show you 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 notice short flashes or an alternating slow flash as it transmits a fault code.
