Always turn off the gas and open windows before fixing. Check your manual for more safety tips. Important safety steps include:
- Regularly check the thermocouple and pilot tube for dirt or blockages
- Look for kinks or damage in the flex tubes
- Make sure there’s good venting and airflow around the pilot light
By following these steps and knowing about thermocouple issues, you can stay safe. If you’re not sure or feel unsure, get help from a pro.
Common Causes of Pilot Light Failure
It’s really frustrating when your pilot light won’t stay lit. Let’s look at some common reasons for pilot light failure. Issues often come from thermocouple problems, gas line issues, or not enough air for burning.
A bad thermocouple can cause the pilot light to fail. This happens because thermocouples wear out over time. They only work well about 30% of the time.
Other common reasons include:
- A dirty pilot light opening can make flames weak and easy to put out.
- Kinks or twists in gas tubes can stop gas from flowing right.
- A broken gas regulator can also stop gas from flowing right.

Troubleshooting Water Heater Pilot That Won’t Stay Lit
When your water heater’s pilot light won’t stay lit, it’s really frustrating. You might not have hot water. Start by checking a few things. Make sure the gas valve is fully open. A valve that’s not fully open can stop the pilot light from staying lit.
Then, look at the thermocouple. Problems with this part are common. The thermocouple checks for a flame and tells the gas valve to keep the gas flowing. If it’s broken, the pilot light won’t stay lit. Use a multimeter to test it. A good thermocouple should show a voltage of 25-30 millivolts.
Also, check the gas line for damage or blockages. A clogged or bent gas line can stop the pilot light from getting gas. Look at the gas control valve too. A bad valve can also stop the pilot light. Regular checks and maintenance can help avoid these problems and keep your water heater working well.
| Component | Issue | Solution |
|---|---|---|
| Thermocouple | Faulty or damaged | Replace with a new thermocouple |
| Gas control valve | Faulty or clogged | Replace with a new gas control valve or clean the existing one |
| Gas line | Clogged or kinked | Clear or replace the gas line |
Step-by-Step Pilot Light Relighting Process
First, find and fix the problem. Then, it’s time to light your pilot light. We’ll show you how to do it right. You’ll learn how to light it, keep it burning, and check if it’s working.

Here are some tips for pilot light maintenance:
- Check the pilot light and thermocouple for dirt often.
- Make sure there’s good air flow to avoid gas buildup.
- Always follow the maker’s guide for relighting pilot light and gas water heater repair.
Conclusion: Ensuring Long-Term Pilot Light Performance
To keep your water heater’s pilot light burning well, regular maintenance is key. About 70% of homeowners face pilot light problems. But, by taking a few easy steps, you can lower these risks a lot.
Check your pilot light every 3-6 months. This can cut down pilot light issues by 40%. Make sure the flame is blue and 1-2 inches tall. If it’s yellow or orange, it’s not working right and might need a new thermocouple.
Replacing a bad thermocouple can cost $20-$100. This can save you money on professional help. Also, cleaning the tank and getting a yearly check-up can make your heater 30% more efficient. It can also last 5-10 years longer.
