The basic steps to relight a pilot light

Most oven pilot lights can be relit by hand in under a minute. Turn the oven's control knob to the pilot position (usually marked with a small flame icon), hold a long lighter or lit match near the pilot opening at the bottom of the oven, and press the ignition button or turn the knob slightly to release gas. The pilot flame should catch within a few seconds. Once it lights, keep the knob pressed in for 30 to 60 seconds so the thermocouple — a small metal rod that senses heat — warms up and signals the gas valve to stay open.

If you do not have a long lighter, a wooden match held in a clothespin or tweezers works just as well. The key is getting the flame close enough to the pilot opening without burning your hand. After the 30 to 60 seconds, slowly release the knob. If the pilot stays lit, turn the knob to the normal "on" position and your oven is ready to use.

If the pilot goes out as soon as you release the knob, the thermocouple may be dirty or failing. Try the process again, but this time hold the knob in for a full 90 seconds. If it still will not stay lit, the thermocouple likely needs cleaning or replacement.

Key Takeaways

  • Turn the control knob to pilot position, hold a flame near the pilot opening, and press the ignition button or turn the knob to release gas.
  • Keep the knob pressed in for 30 to 90 seconds after the pilot lights so the thermocouple warms up and holds the gas valve open.
  • A long lighter or wooden match in tweezers works for lighting; the goal is getting flame close to the opening without burning yourself.
  • If the pilot goes out when you release the knob, the thermocouple is likely dirty or worn and may need cleaning or replacement.

Where to find the pilot opening on your oven

The pilot opening is a small hole or tube at the bottom front of the oven, usually near the left side. On some models it is inside a small metal box or shield; on others it is straightforward an opening in the oven floor. Look for a thin metal rod sticking out slightly — that is the thermocouple. The pilot opening itself is just below or beside it.

If you cannot locate it, check your oven's manual or look inside the oven with a flashlight while the door is open. The opening is always at the base of the oven, never higher up. Some ovens have a removable cover plate that you may need to lift to see the pilot clearly.

Why your pilot light keeps going out

The most common reason is a dirty thermocouple. When dust or grease builds up on the rod, it cannot sense the pilot flame properly, so the gas valve closes even though the pilot is still burning. You can clean it by gently rubbing the thermocouple rod with a soft cloth or fine steel wool while the pilot is off. Do not bend it or explore heavy pressure.

A second reason is a draft or air current blowing out the pilot. If your oven is near a window, door, or heating vent, try closing those sources of air and relighting. If the pilot stays lit after that, you have found the problem.

A third reason is a failing thermocouple itself. If cleaning does not help and you have held the knob in for a full 90 seconds, the rod may be worn out and need replacement. This is a job for a technician, as it involves disconnecting gas lines.

When to call a professional instead

If you smell gas while trying to light the pilot, stop when ready and do not attempt to light it again. Turn off the oven's gas valve (usually a knob on the line behind or below the oven) and call a gas technician or your utility company's emergency line. A gas leak is a safety issue.

If the pilot will not light at all after three attempts, or if it lights but the oven burner will not ignite when you turn the knob to "on," the problem is likely beyond a straightforward relight. A technician can test the ignition system, gas lines, and valves to find the real cause.

If your oven is still under warranty, contact the manufacturer before attempting any repairs yourself. Some repairs done at home can void the warranty.

Tools and materials you will need

A long lighter (the kind used for candles or grills) is the easiest tool. If you do not have one, a wooden match, a clothespin, and tweezers will work. Some people use a thin piece of wire or a straightened paperclip to hold a match steady, though this is less safe than a clothespin.

If you suspect the thermocouple is dirty, have a soft cloth or very fine steel wool on hand. Do not use coarse steel wool or sandpaper, as these can damage the rod. A flashlight is useful for seeing inside the oven clearly.

You do not need any special chemicals or products. The pilot light system is straightforward and mechanical — it relies only on heat, gas, and a metal rod that senses temperature.

Testing whether the pilot is actually lit

After you release the knob, look inside the oven for a small blue flame at the pilot opening. It should be steady and about the size of a match flame. If you see an orange or yellow flame instead, the pilot is burning but the gas mix may be off — this is not a safety issue, but it means the oven may not heat evenly. A technician can adjust the gas-air mix if needed.

If you see no flame at all after releasing the knob, the pilot did not catch. Wait a minute for any gas to clear, then try again. Do not attempt more than three times in a row, as gas can build up in the oven.

How to prevent pilot light problems

Keep the area around the pilot opening clean. Dust and grease are the main culprits. If you spill something in the oven, wipe it up promptly so it does not drip onto the pilot assembly. Do not store items directly in front of the pilot opening, as they can block airflow.

Have your oven serviced once a year if you use it regularly. A technician can clean the thermocouple and check the gas lines before problems start. This is especially important if you live in a dusty area or if your oven is in a kitchen with a lot of cooking smoke.

Frequently Asked Questions

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

Hold it for 30 to 60 seconds on the first try. If the pilot goes out when you release it, try again and hold for a full 90 seconds. The longer hold gives the thermocouple time to warm up and signal the gas valve to stay open. If 90 seconds does not work, the thermocouple likely needs cleaning or replacement.

Can I light the pilot with a regular match instead of a lighter?

Yes. Hold the match in tweezers or a clothespin to keep your hand away from the oven opening. Light the match, position it near the pilot opening, and proceed as you would with a lighter. Wooden matches work better than paper matches because they burn longer and hotter.

What does it mean if the pilot flame is orange instead of blue?

An orange or yellow flame means the gas-air mix is not ideal, usually because there is too much gas or not enough air. The pilot will still work, but your oven may not heat evenly. A technician can adjust the air shutter on the pilot assembly to fix this. It is not an emergency, but it is worth addressing if you notice it.

Is it safe to light the pilot myself, or should I call a technician?

Lighting the pilot yourself is safe as long as you do not smell gas and you follow the steps carefully. If you smell gas at any point, stop and call your utility company's emergency line. If the pilot will not light after three attempts, or if you are uncomfortable working with gas appliances, call a technician instead.

How often do pilot lights go out?

A healthy pilot light should stay lit indefinitely. If yours goes out regularly — more than once a month — something is wrong. Common causes are a dirty thermocouple, a draft, or a failing thermocouple that needs replacement. Have it checked by a technician if it becomes a recurring problem.
