How a Pressure Switch Works
This part plays a prominent duty as your furnace prepares to warm your home.
Here’s what happens after your thermostat’s call for heat:
- Your furnace’s control board begins 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 plenty of air is being pulled into the burners, it closes and signals the control board to ignite the furnace.
- Your furnace ignites and supplies heat.
What Happens When a Pressure Switch Breaks Down
When your pressure switch isn’t functioning promptly, you’ll likely hear the fan run and the switch clicking a few times before the furnace turns off completely. When a part isn’t working right, your furnace will turn off as a safety precaution.
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 notice fast 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 Sunbeam Service Experts Heating & Air Conditioning Expert will investigate other parts of your furnace first. Several other issues can also generate the error code, like a blocked vent or cracked hose.
The bill to fix 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.
