How a Pressure Switch Works
This part plays an important part as your furnace prepares to heat your house.
Here’s what happens after your thermostat’s call for heat:
- Your furnace’s control board begins 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 tells 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 promptly, you’ll likely hear the fan going and the switch clicking a few times before the furnace turns off completely. When a part isn’t performing right, your furnace will turn off to protect you.
Your furnace will show you something is incorrect 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 fast flashes or an alternating slow flash as it passes on a fault code.
