How a Pressure Switch Works
This part plays a critical role as your furnace prepares to heat your home.
Here’s what occurs after your thermostat’s call for heat:
- Your furnace’s control board starts running the draft inducer blower motor. This drains 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 creates heat.
What Happens When a Pressure Switch Fails
When your pressure switch isn’t functioning the way it should, you’ll likely hear the fan run and the switch clicking multiple 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 tell you something is wrong with a red flash from its indicator light, which it uses to exhibit 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.
