How a Pressure Switch Works
This part plays a prominent role as your furnace prepares to warm your space.
Here’s what goes on after your thermostat’s call for heat:
- Your furnace’s control board starts running the draft inducer blower motor. This exhausts 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 tells the control board to ignite the furnace.
- Your furnace ignites and supplies heat.
What Happens When a Pressure Switch Malfunctions
When your pressure switch isn’t functioning the way it should, you’ll likely hear the fan start and the switch clicking a couple times before the furnace shuts down completely. When a part isn’t performing right, your furnace will turn off to protect you.
Your furnace will show you 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 quick flashes or an alternating slow flash as it passes on a fault code.
Estimated Repair Cost for Furnace Error Code 228
Before replacing the switch, your Teays Valley Service Experts Heating & Air Conditioning technician will check other parts of your furnace first. A handful of other issues can also create the error code, like a blocked vent or cracked hose.
The cost to fix your furnace depends on what’s wrong 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.
