If your heater is performing up, you most likely require to know how to clean gas heater pilot light components prior to you spend a fortune on a service call. It's 1 of those annoying little maintenance jobs that sounds far more intimidating than it actually is. Most of the particular time, a heater that won't stay lit isn't in fact "broken"—it's just filthy.
Consider it: that tiny small flame is burning 24/7 during the particular winter. Over period, dust, pet curly hair, and carbon deposits start to create up inside the particular pilot tube. Eventually, the flame will get weak, turns a weird color, plus stops doing its job. But don't worry, you don't need to be a licensed local plumber to get things back in purchase. Let's walk via how to get that flame azure and strong once again.
Why Does a Pilot Light Get Dirty In any case?
It's easy to forget that your gas heater is essentially "breathing" the air in your house. Because the heater pulls in air for burning, it also drags in whatever is floating around—dust bunnies, dander, and lint. When these particles hit the pilot light assembly, these people burn off and keep behind a thin layer of soot or "carbon buildup. "
If you see your pilot light has a lazy, flickering yellow flame instead of a sharp, steady blue one, that's a dead free items. A yellow fire is "cool" and weak; it doesn't have the heat necessary to keep the particular thermocouple (the small safety sensor) hot enough to maintain the gas valve open. When that occurs, your heater turns off as a safety precaution. It's frustrating, but it's actually your heater doing its job to keep a person safe.
What You'll Need Just before You Start
You don't need a specialized tool set for this. In fact, you probably possess the majority of this stuff sitting in a rubbish drawer or below the sink. Get these items:
- A can of compressed air (the kind you make use of for keyboards)
- An old toothbrush or a small wire brush
- An item of fine-grit sandpaper or an emery cloth
- A flashlight (it's darkish in there! )
- A damp publication
Safety First: Don't Skip This Part
Before we even contact the pilot set up, we now have to speak about safety. Functioning with gas isn't something to end up being flippant about.
First, turn the gas valve to the 'OFF' placement . Usually, there's a knob on the heater itself, and frequently a shut-off valve on the gas line leading to the system. Turn all of them both off.
Second, in the event that the heater had been just running, wait at least 20 or 30 minutes. Those metal parts get incredibly warm, and also you really don't want to discover that your difficult way by grabbing a scalding very hot pilot tube. As soon as everything feels awesome to the contact, you're good to go.
Step 1: Locating the Pilot Light Assembly
Every heater is a little different, but most possess a detachable front panel or a small access door. Pop that will off, and use your flashlight to choose a small metal tube that sits right next to the primary burner.
You'll see two main parts: the pilot orifice (where the gas comes out) and the thermocouple (a small metal rod that the flame hits). These are usually the two areas where dirt likes to hide. If you see a group of gray lung burning ash or black soot around them, you've found your culprit.
Step two: Clearing Out the Dust
Sometimes, the "fix" is as simple as a puff of air. Dust can negotiate right in the pilot tube, choking away the gas stream. Take your can of compressed air flow and give the pilot opening a few good blasts.
Don't stay the nozzle directly into the pit; just hold this about an inch away and apply. You might discover a little cloud of dust soar out. In case you don't have compressed air flow, you can in fact work with a drinking hay to blow in to it, though it's not quite as effective (and you may get a face filled with dust, so close your eyes! ).
Step several: Scrubbing the Pilot Orifice
When the air didn't do the technique, or if a person can see noticeable gunk on the metal, it's time for the toothbrush. Gently—and I mean gently —scrub the tip of the particular pilot light pipe. You're trying to dislodge any carbon dioxide deposits that are preventing the gas through coming out within a clean stream.
If the buildup is really stubborn, a person can use a very thin piece of wire (like a needle or the strand from a wire brush) to meticulously poke to the opening. Just be super careful not to "reams" the opening out or allow it to be bigger. You just want to clear the blockage, not replace the shape of the nozzle.
Step 4: Washing the Thermocouple
This is the step people frequently miss when studying how to clean gas heater pilot light parts. The thermocouple is that little metal rod that sits right in the path of the flame. It's a safety device; if this doesn't get hot enough, it shows the gas device to shut down so gas doesn't leak into your own house.
Soot acts like insulation on the thermocouple. If it's covered in black carbon, it won't "feel" the heat of the flame, and it'll shut the particular system down even if the pilot is theoretically lit.
Take your fine-grit sandpaper or emery cloth and lightly rub the tip of the thermocouple. You want to see shiny metal again. You don't need to proceed crazy—just a few passes until the dark soot is fully gone. Wipe it down with your damp cloth afterward to make sure there's no resolution left behind.
Step 5: Putting Everything Back Together
Once every thing looks clean and shiny, give the area one final wipe together with your publication to grab any loose debris a person knocked loose. Create sure the pilot tube and the thermocouple continue to be lined up properly. The thermocouple should be situated so that the particular pilot flame may directly engulf the top half-inch of the rod.
Right now, replace any sections you removed and obtain ready to test out your handiwork.
Relighting the Pilot
Now for the particular moment of truth. Turn your gas valve back to the 'PILOT' place. Most heaters require you to press and hold the particular knob down whilst you hit the particular igniter button (or use a lengthy lighter).
After the flame catches, keep on holding the button down for approximately 30 to one minute. This provides the thermocouple period to warm up plus "tell" the control device that it's secure to keep your gas flowing. Slowly let go of the knob. If the particular flame stays lighted, you've done this! Turn the button to the 'ON' position, as well as your heater should kick best over.
How to Tell if It Worked
A healthy pilot light should end up being a steady, bright blue color with maybe a tiny bit of yellow hue at the pretty tip. It need to resemble a small, sharp blowtorch flame, not a flickering candlestick. It should also be hitting the thermocouple directly.
If the flame is definitely still yellow, "lazy, " or making a whistling sound, there might end up being a deeper blockage or a problem with the particular gas pressure. Yet 90% of the time, that quick cleaning is usually all it will take to get things back to regular.
When Ought to You Call the Professional?
Whilst knowing how to clean gas heater pilot light devices is an excellent DIY skill, occasionally the problem is bigger than a small dust. If you've cleaned everything plus the pilot still won't stay lighted, the thermocouple may be totally burnt away and need replacement. They're cheap parts, but if a person aren't comfortable replacing out hardware, contact a tech.
Also, if you ever smell a strong "rotten egg" odor (mercaptan) even when the gas is turned off, stop what you're doing immediately. Go out and contact the gas organization. DIY is great for cleaning, but gas leaks are a whole different ballgame.
Keeping This Clean for Next Year
The best way to avoid this head ache next winter is to give the pilot area the quick blast of air once a year prior to the chilly weather starts. Just a little preventative maintenance goes a long method. Keeping the area about your heater obvious of dust plus clutter helps as well, as it gives the unit "cleaner" air to breathe in.
At the end of the day, a bit of sandpaper and a toothbrush can save a person a $150 service call. It's the simple fix that'll keep your home warm and your heater running efficiently all season longer. Now go enjoy that heat!
