Absolutely nothing is quite such as waking up to a freezing house only to recognize you need to determine how to restart a furnace pilot light before the indoor temp hits refrigerator amounts. It's one of those classic home owner "uh-oh" moments that will feels a lot more overwhelming than it really is. Many people assume that will when the heat isn't kicking on, they're looking at a massive repair bill, but most of the time, it's just that little glowing blue flame that decided to call it quits.
For those who have an older furnace, it likely relies on a standing pilot light. This is a small, continuous flame that will stays lit almost all the time so it can ignite the primary burners whenever the particular thermostat calls for heat. If a draft blows it out or a little bit of dust gets in the manner, the whole system shuts down since a safety safety measure. Knowing how to have it going again is a skill that'll save you a lot of shivering and a potentially costly service call.
First, let's talk about safety
Before you proceed poking around in the guts associated with your heating system, we now have to deal with the elephant in the room: fuel. You're dealing with organic gas or gas, so you need to use your nose. In case you scent something like spoiled eggs or a skunk, stop what you're doing immediately . That's the fragrance manufacturers add to gas so a person can detect leakages. If the smell is strong, obtain everyone out associated with the house and call the gas company from outdoors.
However, in case you don't smell something and it's simply cold, you're probably fine to move forward. Most furnaces possess a built-in basic safety valve that turns off the gas flow if the pilot light will go out, which helps prevent your basement through filling up along with fumes. Still, it's a good idea to turn the furnace's gas valve to "Off" plus wait about five or ten minutes before you try out to relight this. This gives any kind of residual gas a chance to desolve, just to end up being safe.
Locating the pilot light assembly
Once you've waited a few minutes, you'll need to find where the magic happens. Look regarding a small doorway or a detachable panel within the front side of your furnace. Behind that section, you'll usually observe a bunch of pipes and a control knob. This knob should possess three settings obviously marked: On, Off, plus Pilot .
Follow the little copper tube leading from that handle valve; it'll guide you right to the pilot burning. It's usually tucked away near the main burner tubes. A person might need a flashlight to notice clearly because these corners can get pretty dark plus dusty. If you see a small metal rod sitting down right next to where the flame should be, that's the thermocouple. We'll talk more about that finicky little bit of piece of equipment in a bit, but for now, just note exactly where it really is.
How to restart a furnace pilot light step-by-step
Fine, let's get straight down to business. In case you've got your long-reach lighter or a fireplace match up ready, here is definitely the basic work flow for getting that flame back to life.
- Turn the button to "Off" if you haven't already. Wait a couple of minutes for any gas to clean out.
- Turn the knob to "Pilot. " This tells the program you're ready to light it personally.
- Discover the reset key. On many models, the particular knob itself will be the button—you'll want to push it down. On others, there might be a separate reddish button nearby.
- Get a flame ready. Hold your lit up match or lighter in weight near the pilot burner.
- Push and contain the knob/button. While you're holding it down, the gas will start flowing to that will specific tiny burner. You should see the particular pilot light fire up almost instantly.
- Don't release yet! This is the part where nearly all people mess upward. You have to keep holding that switch down for about 30 to sixty seconds.
- Slowly release the particular button. If the fire stays lit, you're golden.
- Turn the knob to the "On" position. This enables the main burners to lastly kick in.
You should listen to a satisfying whoosh as the main burners fire up once you turn it to "On" and the thermostat is set to heat. If the pilot light flickered and passed away the moment a person let go associated with the button, don't worry—it happens. Just wait a minute and try again, perhaps holding the particular button down a bit longer this particular time.
Precisely why won't the pilot light stay lighted?
If you've tried the actions above a few instances and the fire just keeps venturing out the second you release the switch, you're likely dealing with a thermocouple problem . The thermocouple is a protection sensor that picks up heat. If this doesn't get hot good enough, it tells the particular gas valve to shut down because it thinks there's simply no flame. It's a "fail-safe" to maintain gas from pumping into your house.
Sometimes the particular thermocouple just gets dirty. A very little bit of soot or carbon buildup can insulate this from the temperature, which makes it think the flame isn't there. You can sometimes fix this by gently cleaning it along with a piece of fine sandpaper or a dry material once it's cool.
Another common culprit is definitely a simple draft. If your furnace is in a drafty basement or near a doorway that opens regularly, a sudden gust of air may literally blow the particular pilot light out there. Issue is a recurring problem, you may need to look into ways to shield the area or check if your venting program has issues.
When it's time to get in touch with the pros
I'm all for a good DIY repair, but there are times when you simply have to acknowledge defeat and call a technician. If the pilot light fire is yellow or orange instead of a crisp blue, that's an indication that the burning is dirty or not getting more than enough oxygen. A healthful pilot light should be a stable blue cone that will wraps around the tip of the particular thermocouple.
Furthermore, if you effectively relight the furnace but it will go out again a few hours later on, you likely possess a failing thermocouple or a defective gas valve. These types of parts are relatively cheap, but if a person aren't comfortable functioning with gas ranges and small parts, it's much more secure to let a professional handle the particular replacement. It'll provide you with peace of thoughts knowing the job was done correct and that your house isn't going to turn into a giant ice cube in the center of the night.
Keeping things operating smoothly
To avoid having to search for how to restart a furnace pilot light in the future, a little bit of maintenance goes a lengthy way. Each year, just before the cold climate really hits, it's worth opening up the furnace and blowing out any kind of dust or cobwebs with a may of compressed air flow. Keeping the region about the furnace clear of clutter also helps with airflow plus reduces fire hazards.
It's furthermore worth noting that if you possess a much newer furnace, you might not have a pilot light from all. Most contemporary systems use digital ignition—either a "hot surface igniter" that will glows orange or even a "spark igniter" that clicks such as a gas barbeque grill. If those systems fail, you won't be able to light these a complement. You'll usually see a blinking DIRECTED light on the furnace control plank that flashes a code telling you exactly what's wrong.
In the end, the actual basics of your home heating is just part of getting a responsible adult, even if it's not the almost all exciting way to spend a Saturday morning. Once you've got that flame back on plus the house starts to warm up, you'll feel like a total hero. Just remember to put the furnace cover back upon correctly and probably treat yourself to a hot coffee—you've earned it!
