How a Pressure Switch Works
This part plays聽a prominent聽role聽as your furnace prepares to聽work in聽your聽space.
Here’s what聽happens聽after your thermostat’s call for heat:
- Your furnace’s control board聽starts聽running the draft inducer blower motor. This聽drains聽combustion gases from the heat exchanger and聽pulls聽in new gas and air so the burners can fire.
- When the pressure switch senses that聽sufficient聽air is being pulled into the burners, it closes and聽signals聽the control board to ignite the furnace.
- Your furnace ignites and聽provides聽heat.
What Happens When a Pressure Switch聽Fails
When your pressure switch isn’t聽working聽promptly, you’ll likely hear the fan聽run聽and the switch clicking聽multiple聽times before the furnace聽shuts down聽completely. When a part isn’t聽performing聽right, your furnace will turn off聽as a safety precaution.
Your furnace will聽let you know聽something is聽incorrect聽with a red flash from its indicator light, which it uses to聽exhibit聽error codes. It uses this red light to flash code, like Morse code.
You may聽see聽short聽flashes or an alternating slow flash as it聽communicates聽a fault code.
