How a Pressure Switch Works
This part plays an important part as your furnace prepares to warm your house.
Here’s what occurs after your thermostat’s call for heat:
- Your furnace’s control board commences 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 enough 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 functioning promptly, you’ll likely hear the fan run and the switch clicking multiple times before the furnace shuts down completely. When a part isn’t working right, your furnace will turn off for your safety.
Your furnace will show you something is wrong 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 short flashes or an alternating slow flash as it transmits a fault code.
