The Basic Steps to Light Your Oven's Pilot Light

To light a pilot light in an oven, you need to locate the pilot assembly (usually at the bottom of the oven or inside the firebox), turn the gas knob to the pilot position, hold a lit match or lighter near the pilot opening, and keep the knob pressed for 30 to 60 seconds after the flame catches. The exact location and procedure depend on your oven model, so checking your manual first saves time and prevents mistakes.

Most ovens have the pilot assembly visible when you open the oven door and look at the bottom or sides of the interior. Some models hide it behind a removable panel or require you to remove the oven racks to see it clearly. If you cannot find it after a quick look, consult your manual or the manufacturer's website — they often have diagrams showing exactly where yours is located.

Key Takeaways

  • The pilot light sits at the bottom or side of your oven interior, and you light it by holding a flame near the opening while the gas knob is set to pilot position.
  • You must keep the knob pressed down for 30 to 60 seconds after the flame ignites so the thermocouple heats up and stays open.
  • If the pilot will not stay lit after you release the knob, the thermocouple may be dirty or failing, and you should clean it with a soft brush or call a technician.
  • Never use a lighter or match if you smell gas in the kitchen — turn off the gas supply and open windows instead.
  • Some newer ovens have electronic ignition and no pilot light, so check your manual to confirm your model has one before you start.

Locating Your Oven's Pilot Assembly

Open the oven door fully and look at the bottom interior, usually toward the back or to one side. You are looking for a small metal tube with an opening about the size of a pencil tip. On many models, it sits near the edge of the oven floor or along the side wall. The tube connects to a small metal box or bracket — that is the thermocouple, which senses when the pilot is lit and tells the gas valve to stay open.

If you do not see it when ready, check whether your oven has a removable bottom panel or floor. Some models require you to lift or slide out a metal plate to access the pilot. Your manual will show you how to remove it safely. If you have lost the manual, search the manufacturer's name and model number online — most companies post PDF manuals on their websites for free.

On a few older or commercial-style ovens, the pilot assembly sits inside a small chamber you reach from the side or back of the oven. Do not force anything open. If the pilot is not visible after a reasonable search, stop and consult the manual rather than guessing.

Preparing to Light the Pilot

Before you strike a match, make sure the oven is completely cool. If you have just used the oven, wait at least 30 minutes. A hot oven can ignite a match or lighter before you are ready, and the heat can also prevent the pilot from staying lit because the thermocouple may already be warm.

Gather your tools: a long lighter or long-stemmed match works best because it keeps your hand farther from the pilot opening. A regular match can work if you hold it carefully, but you risk burning your fingers. Have a flashlight or phone light ready so you can see inside the oven clearly — the pilot opening is small, and poor lighting makes the job harder.

Check that the oven's gas supply is on. If you have a gas valve outside the oven (usually on the line coming into the appliance), make sure it is turned to the open position. If you are unsure whether gas is flowing, you may smell a faint gas odor near the pilot opening — that is normal. If the smell is strong or you smell gas elsewhere in the kitchen, turn off the gas supply when ready and open windows before proceeding.

Lighting the Pilot Step by Step

Turn the oven's temperature knob or control dial to the pilot position. On most ovens, this is a separate setting marked "Pilot" or "Light Pilot," usually found by turning the knob all the way counterclockwise or to a marked position. Some older models have a small button you press instead. If your knob does not have a pilot setting, your oven may have electronic ignition and no traditional pilot light — check your manual to confirm.

Once the knob is set to pilot, press and hold it down. This opens the gas valve so gas flows to the pilot opening. While holding the knob, bring your lit match or lighter to the pilot opening and hold the flame there. You should see a small blue flame ignite within a few seconds. If nothing happens after 10 seconds, release the knob, wait 30 seconds for any gas to clear, and try again.

After the pilot flame appears, keep the knob pressed down for another 30 to 60 seconds. This allows the thermocouple to heat up. The thermocouple is a heat-sensing device that tells the gas valve to stay open once you release the knob. If you let go too soon, the pilot will go out because the thermocouple has not warmed enough yet. Count slowly to 60 to be safe.

Slowly release the knob. The pilot flame should stay lit. If it goes out when ready, the thermocouple is likely not working properly — see the troubleshooting section below. If the flame stays on, turn the knob to the normal oven temperature setting. The main burner should ignite, and you are done.

What to Do If the Pilot Will Not Stay Lit

If the pilot light goes out as soon as you release the knob, the thermocouple is probably the problem. This small metal rod senses heat from the pilot flame and signals the gas valve to open. When it fails, the valve closes even though the pilot is burning. Before you call a technician, try cleaning the thermocouple.

Turn off the gas supply and let the oven cool completely. Locate the thermocouple — it is the thin metal rod sitting just to the side of the pilot opening, usually held in place by a small bracket. Gently brush the tip of the thermocouple with a soft, dry brush or a clean cloth to remove any dust or soot. Do not scrub hard or bend the rod. Turn the gas back on and try lighting the pilot again.

If cleaning does not work, the thermocouple may be bent, corroded, or failing internally. A bent thermocouple can sometimes be carefully straightened, but if it is corroded or broken, it needs to be replaced. Replacement thermocouples are inexpensive (usually under $30) and available online or from appliance parts suppliers, but installation requires some mechanical skill. If you are not comfortable doing it yourself, a technician can replace it in under an hour.

Safety Precautions and Common Mistakes

Never attempt to light a pilot if you smell strong gas in the kitchen. Turn off the gas supply at the main valve or the oven's gas line, open all windows, and leave the area. A strong gas smell means there is a leak, and striking a match could ignite it. Call your gas company's emergency line or a technician before trying again.

Do not hold the knob down for longer than a few minutes. If the pilot will not light after two or three attempts, stop and wait 30 seconds before trying again. Holding the knob open too long floods the oven with gas, which is a fire hazard and makes it harder for the pilot to ignite.

Avoid touching the thermocouple or pilot opening with your bare hands after the oven has been in use. Even if the oven feels cool, these parts can retain heat. Always wait at least 30 minutes after using the oven before working on the pilot.

If your oven has an electronic ignition system instead of a pilot light, you cannot light it manually. Electronic ignition ovens have a spark or glow plug that ignites the gas automatically when you turn on the oven. If the ignition is not working, the problem is electrical, not a missing pilot flame. Consult your manual or call a technician.

When to Call a Professional

If you have followed the steps correctly and the pilot still will not light after cleaning the thermocouple, a technician should inspect the oven. The problem could be a faulty gas valve, a blocked pilot tube, or a broken igniter in electronic models. These repairs require specialized tools and knowledge.

You should also call a professional if you smell gas but cannot find a leak, if the pilot flame is yellow or orange instead of blue, or if the oven does not heat properly even after the pilot is lit. A yellow or orange flame suggests incomplete combustion, which can indicate a clogged burner or a ventilation problem. These issues are not dangerous to fix yourself, but they do require professional diagnosis.

Frequently Asked Questions

How long should I hold the knob down after the pilot lights?

Hold it for 30 to 60 seconds. This gives the thermocouple time to heat up and signal the gas valve to stay open. If you release too soon, the pilot will go out. If you hold it longer, that is fine — just do not exceed a few minutes, as that wastes gas.

What if I cannot find the pilot light in my oven?

Check your oven's manual first — it will show you exactly where the pilot is located on your model. If you have lost the manual, search online for your oven's brand and model number. Some ovens have electronic ignition instead of a pilot light, so your manual will tell you whether yours has one.

Is it safe to use a regular match instead of a lighter?

Yes, but a long-stemmed match or long lighter is safer because it keeps your hand farther from the flame. A regular match works, but you need to hold it steady and close to the pilot opening, which increases the risk of burning your fingers.

Why does the pilot light keep going out?

The thermocouple is usually the culprit. It senses the pilot flame and tells the gas valve to stay open. If it is dirty, bent, or failing, the valve closes even though the pilot is burning. Try cleaning it with a soft brush first. If that does not work, it may need to be replaced.

Can I light the pilot if the oven is still warm?

It is better to wait until the oven is completely cool. A warm oven can make it harder for the pilot to stay lit because the thermocouple may already be warm. Wait at least 30 minutes after using the oven before lighting the pilot.
