How a Pressure Switch Works
This part plays a prominent role as your furnace prepares to work in 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 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 operating promptly, you’ll likely hear the fan going and the switch clicking a couple times before the furnace turns off completely. When a part isn’t functioning right, your furnace will turn off for your safety.
Your furnace will let you know something is amiss with a red flash from its indicator light, which it uses to present 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.

The price to repair your furnace depends on what’s defective with it and how long it takes to fix it.
If your pressure switch needs to be replaced, you can plan to pay between $40 to $350.
