How a Pressure Switch Works
This part plays a critical duty as your furnace prepares to heat your house.
Here’s what happens after your thermostat’s call for heat:
- Your furnace’s control board commences running the draft inducer blower motor. This pushes out combustion gases from the heat exchanger and brings 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 provides heat.
What Happens When a Pressure Switch Fails
When your pressure switch isn’t functioning 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 performing right, your furnace will turn off for your safety.
Your furnace will tell 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 note quick flashes or an alternating slow flash as it passes on a fault code.
