How a Pressure Switch Works
This part plays an important duty as your furnace prepares to work in your space.
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 moves 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 signals the control board to ignite the furnace.
- Your furnace ignites and provides heat.
What Happens When a Pressure Switch Breaks Down
When your pressure switch isn’t functioning correctly, you’ll likely hear the fan going and the switch clicking multiple times before the furnace shuts down completely. When a part isn’t performing 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 short flashes or an alternating slow flash as it transmits a fault code.

Before replacing the switch, your Winnipeg Supply Service Experts tech will investigate other parts of your furnace first. Some other issues can also generate the error code, like a clogged vent or cracked hose.
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 expect to pay between $40 to $350.
