We’ll also cover common myths, maintenance advice, and answer the most frequently asked questions on this topic. By the end, you’ll feel confident about the inner workings of your gas stove—no matter what model you own.
What Is A Pilot Light?
A pilot light is a small, steady flame that burns constantly inside some gas appliances. Its main purpose is to act as an ignition source. When you turn on the gas, the pilot light ignites the gas, creating the larger flame you use for cooking.
The pilot light is usually hidden from view, placed near the burners or inside the oven compartment. It burns a small, continuous stream of gas, ready to light the main burner when needed. This system was common in older gas stoves and is still found in some homes today.
How Does A Pilot Light Work?
A pilot light works by using a tiny tube (called a pilot tube) that delivers gas from the main supply. This gas is ignited and kept burning by a small flame. When you turn your stove knob, gas flows to the main burner, and the pilot flame lights it instantly.
To keep things safe, most pilot systems include a thermocouple—a safety device that senses heat from the flame. If the pilot goes out, the thermocouple shuts off the gas, preventing leaks. This is a critical feature because unburned gas can be dangerous.
Where Can You Find Pilot Lights?
You’ll usually find pilot lights in:
- Older gas stoves (especially those made before the 1980s)
- Some commercial kitchen equipment
- Gas ovens and water heaters
If you have a newer residential stove, it’s less likely to have a pilot light. But in older homes or vintage appliances, pilot lights are common.
Types Of Gas Stove Ignition Systems
Over the years, the way gas stoves light their burners has changed. Today, two main systems are used: pilot lights and electronic ignition. Understanding the differences will help you identify your stove’s system and maintain it properly.
1. Standing Pilot Light
This is the traditional system. The pilot light stays on all the time, even when the stove is not in use. It uses a small amount of gas continuously.
Pros:
- Simple technology, easy to understand
- Works even during a power outage
Cons:
- Wastes gas (pilot burns 24/7)
- Needs occasional relighting and maintenance
2. Electronic Ignition
Most modern gas stoves use electronic ignition. When you turn the knob, a small electric spark lights the gas—no pilot flame needed.
Pros:
- Saves energy (no gas burned when not in use)
- Safer (no open flame when stove is off)
- Easier to maintain
Cons:
- Needs electricity (may not work during a blackout)
- More complex parts to repair if something goes wrong
3. Intermittent Pilot (hybrid Systems)
Some newer stoves and ovens use a hybrid system called intermittent pilot. Here, a small pilot flame lights only when needed, then turns off.
Pros:
- Reduces gas waste
- Still allows for reliable ignition
Cons:
- More complex than standing pilots
- Still uses a pilot flame, just not all the time
Comparison Of Ignition Systems
To make it easier, here’s a side-by-side look at the main types:
| Ignition Type | Pilot Flame | Energy Use | Works Without Electricity | Maintenance Needs |
|---|---|---|---|---|
| Standing Pilot | Always On | High (constant gas use) | Yes | Relighting, cleaning |
| Electronic Ignition | No | Low | No | Spark igniter may need service |
| Intermittent Pilot | On Only When Needed | Medium | Sometimes | Occasional maintenance |
Do Most Gas Stoves Today Have Pilot Lights?
In the past, almost every gas stove had a pilot light. But things have changed. Since the late 20th century, most new stoves use electronic ignition instead. This shift happened mainly for two reasons: energy savings and safety.
Why Did Manufacturers Move Away From Pilot Lights?
- Energy Waste: A pilot light can use up to 600 BTUs (British Thermal Units) of gas per hour. That may not sound like much, but over a year, it adds up—sometimes costing $50 or more in extra gas bills.
- Safety: If the pilot light goes out and gas keeps flowing, it can create a dangerous situation. Modern safety systems help, but electronic ignition eliminates this risk.
- Convenience: Relighting a pilot can be tricky and sometimes frustrating. Electronic systems are more reliable for most users.
- Environmental Impact: Constantly burning gas for a pilot light increases carbon emissions. Electronic ignition is more eco-friendly.
Which Gas Stoves Still Have Pilot Lights?
You are more likely to find pilot lights in:
- Stoves made before the mid-1980s
- Some commercial or heavy-duty kitchen ranges
- Areas with unreliable electricity (since electronic ignition needs power)
Most gas stoves sold today in the U.S. do not have standing pilot lights. If you buy a new stove, it will almost always use electronic ignition.
How To Tell If Your Gas Stove Has A Pilot Light
Not sure which system your stove uses? Here are some easy ways to check:
1. Listen For A Clicking Sound
When you turn the burner knob, do you hear a rapid clicking noise? That’s the spark from an electronic ignition system. If you hear nothing, your stove may have a pilot light.
2. Look Under The Burner
- Turn off all burners and let your stove cool.
- Remove the burner grates and look closely near the center.
- A small, blue flame burning all the time means you have a pilot light.
- If you see a small metal rod (with no flame) or a ceramic tip, that’s probably a spark igniter.
3. Check The Owner’s Manual
If you have the manual, it will say which ignition system your stove uses. If you don’t have the manual, search online for your stove’s model number.
4. Power Outage Test
If your burners still light with no electricity, you likely have a pilot light. Electronic ignition needs power.
5. Look For A Reset Or Ignition Button
Some stoves with electronic ignition have a separate button or switch for lighting the burner. Pilot systems usually do not.
Example: Identifying A Pilot Light
Suppose you have a 1970s gas range. You peek under the cooktop and see a small, steady flame. When you turn a burner knob, the main flame lights instantly—no clicking sound. In this case, you have a standing pilot light system.
How To Relight A Pilot Light
If you have a stove with a pilot light, sometimes it goes out. Maybe a draft, spilled liquid, or cleaning knocked it out. Relighting is usually simple, but it’s important to do it safely.
Step-by-step Relighting Guide
- Turn Off All Burners: Make sure no gas is flowing.
- Wait a Few Minutes: This lets any unburned gas dissipate.
- Locate the Pilot Light: Usually under the cooktop or inside the oven. Check your manual if unsure.
- Light a Long Match or Lighter: Use a long-reach lighter for safety.
- Press the Safety Button (if present): Some stoves have a button you must hold while lighting.
- Light the Pilot: Hold the flame at the pilot opening. The flame should catch quickly.
- Hold for 30 Seconds: If there’s a thermocouple, keep holding the button for about 30 seconds to heat the sensor.
- Release and Check: The pilot flame should stay lit. If not, repeat or check for blockages.
Safety Tip: If you smell strong gas, stop and ventilate the area. Do not try to relight. Call a professional.
Pros And Cons Of Pilot Lights Vs. Electronic Ignition
Choosing between a stove with a pilot light and one with electronic ignition depends on your needs. Here’s a closer look at the advantages and disadvantages.
Advantages Of Pilot Lights
- Works During Power Outages: You can still cook if the electricity goes out.
- Simple Technology: Fewer electronic parts mean less can go wrong.

Common Problems With Pilot Lights
While pilot lights are reliable, they do have some typical issues. Knowing these can help you troubleshoot and avoid bigger problems.
1. Pilot Light Won’t Stay Lit
This usually means the thermocouple is dirty or faulty. Cleaning or replacing the thermocouple often solves the problem.
2. Weak Or Yellow Flame
A pilot flame should be small and blue. If it’s yellow or flickering, the pilot tube may be dirty. Cleaning with a small brush or needle can help.
3. Pilot Light Goes Out Repeatedly
Drafts, spilled food, or grease can cause the flame to go out. Make sure the area is clean and shielded from strong air flow.
4. Gas Smell
If you smell gas near your stove, turn off everything and ventilate the room. Do not relight the pilot. Call a professional immediately.
5. Hard To Access
Some older stoves have pilot lights in tricky places. Use a flashlight and long-reach lighter for safety.
Non-obvious Insight: Many people forget that cleaning the area around the pilot light is as important as cleaning the burners. Even small crumbs or grease can block gas flow and cause the pilot to go out.
How Electronic Ignition Systems Work
Electronic ignition stoves use a spark to light the gas. This is how most new stoves operate.
How It Works
- You turn the knob to the “light” position.
- An electrical circuit sends a voltage to a spark module.
- The module creates a rapid clicking sound and makes a visible spark.
- The spark ignites the gas, and the burner lights.
Types Of Electronic Ignition
- Spark Ignition: Most common. Produces a visible spark.
- Hot Surface Ignition: Uses a heated element instead of a spark (more common in ovens than cooktops).
What If The Power Goes Out?
Most stoves with electronic ignition can still be lit with a match if the power is out, but you must be careful. Some newer models have safety features that stop gas flow entirely without electricity. Always check your manual.
Practical Tip: If your spark igniter clicks but does not light, it may be dirty or misaligned. Cleaning with a toothbrush or adjusting its position often fixes the problem.

Safety Features In Modern Gas Stoves
Both pilot light and electronic ignition stoves have important safety features. Here’s what you should know:
Thermocouples And Flame Sensors
- Thermocouple: Senses heat from the pilot light. If the flame goes out, it shuts off the gas.
- Flame Sensor: Used in electronic ignition. Detects if the burner flame is present and cuts gas if not.
Auto Shut-off
Most new stoves cut off gas flow if the burner doesn’t light within a few seconds. This reduces the risk of gas buildup.
Child Lock And Control Knobs
Some stoves have child safety locks or recessed knobs to prevent accidental ignition.
Ventilation
Good ventilation is essential with any gas stove. Install a range hood or exhaust fan to remove fumes and improve air quality.
Non-obvious Insight: Many people think only older stoves need ventilation. In reality, all gas appliances should be vented to avoid buildup of carbon monoxide and other gases.
Environmental And Cost Impact
Pilot lights and electronic ignition systems affect both the environment and your wallet.
Gas Consumption
A standing pilot light uses about 600 BTUs per hour. Over a year, that’s about 5 million BTUs—enough to cook a lot of meals!
Cost
Depending on gas prices, a pilot light can cost $40–$60 per year just to keep burning. Electronic ignition cuts this to almost zero.
Carbon Footprint
Burning gas produces carbon dioxide. Switching to electronic ignition reduces your home’s greenhouse gas emissions.
Example: The U.S. Department of Energy recommends electronic ignition for energy savings and environmental benefits. For more, see the U.S. Department of Energy.
