One Small Sensor, One Big Furnace Problem

Furnaces are still a popular home heating choice, but they have a very unpopular problem. It stems from a safety device, but even so, it can be inconvenient to deal with. This safety feature helps you sleep easy at night and protect your family–until this happens.

We’re talking about your flame sensor: a small sensor that may be preventing your furnace from starting in the first place, and requiring you to get heating repair in Las Vegas, NV. Let’s talk about what it does and why it’s a more in-depth task than it may sound.

Safety First

First and foremost, this sensor is a safety feature that’s designed to cut off the flow of gas. If it cannot detect a live flame from the ignition, it shuts down the gas line. This prevents gas leaks from entering your air, which would be a massive fire hazard and personal safety issue. While it can be frustrating to deal with a flame sensor malfunction, know that it’s there for a very good reason.

So What’s Wrong With It?

It’s more than likely just dirty. Because it’s in contact with burning gas on a semi-constant basis, soot and debris build on the sensor over time (which is one reason it’s good to have annual maintenance appointments).

While it may sound simple to just clean it, the reality is quite far from it. Your flame sensor needs to be taken apart and cleaned piece by piece. When you consider the steps of shutting off your gas, powering down your furnace ignition, disconnecting the flame sensor, etc., it becomes tedious–and beyond that, you may void your furnace warranty if you take the DIY approach.

You Need a Certified HVAC Technician to Handle it For You

Your warranty likely states that work performed on your furnace can only be performed by a professional, certified technician. The reason for this isn’t to dissuade you from working on your own unit, but to ensure that it’s handled by a professional so that any problems that may occur don’t stem from the quality of the work provided.

Beyond that, it’s a safety issue. If you work on your flame sensor without proper knowledge and training, not to mention the right tools, you may damage the sensor so it doesn’t function properly once it’s reinstalled, or reinstall it incorrectly.

While that may not sound bad, remember how important this is for your home safety. This is a job that requires a professional touch 100% of the time.
