Why Won’t My Water Heater Pilot Light Stay Lit?
A water heater is an essential appliance in our daily lives, providing us with hot water for washing, bathing, and other purposes. However, when the pilot light on your water heater goes out, it can be frustrating and inconvenient. In this article, we will explore the reasons why your water heater pilot light won’t stay lit and provide you with some troubleshooting steps to resolve the issue.
Why Won’t My Water Heater Pilot Light Stay Lit?
The pilot light on your water heater is responsible for igniting the main burner, which heats the water. The pilot light is usually electrically controlled and is supposed to stay lit continuously, unless there is a specific reason for it to turn off. If the pilot light won’t stay lit, it can be a sign of a problem with the water heater or one of its components.
Here are some common reasons why your water heater pilot light won’t stay lit:
- Dirty or faulty thermocouple: A thermocouple is responsible for sensing the pilot flame and shutting off the gas supply when the flame goes out. If the thermocouple is dirty or faulty, it may not be able to detect the pilot flame, causing it to shut off.
- Incorrect gas pressure: If the gas pressure in your home is too high or too low, it can affect the pilot light’s ability to stay lit.
- Clogged pilot orifice: If the pilot orifice (the small hole where the pilot flame comes out) is clogged with sediment or debris, it may not be able to flow properly, causing the pilot light to go out.
- Faulty spark generator: The spark generator is responsible for igniting the pilot flame. If it’s faulty, it may not be able to produce a strong enough spark to keep the pilot flame lit.
- Weak or dirty pilot flame: If the pilot flame is weak or dirty, it may not be able to stay lit.
How to Troubleshoot Your Water Heater Pilot Light?
Before calling a plumber or replacing your water heater, you can try troubleshooting the issue yourself. Here are some steps to help you identify the problem:
- Check the gas supply: Make sure the gas supply to your water heater is turned on.
- Check the thermocouple: Clean or replace the thermocouple if it’s dirty or faulty.
- Check the pilot orifice: Clean or replace the pilot orifice if it’s clogged.
- Check the spark generator: Clean or replace the spark generator if it’s faulty.
- Check the pilot flame: Adjust or clean the pilot flame if it’s weak or dirty.
- Check the air shutter: Adjust or clean the air shutter if it’s clogged.
Preventative Maintenance
Preventative maintenance is crucial to keep your water heater pilot light running smoothly and efficiently. Here are some tips to help you keep your water heater in good condition:
- Clean the pilot orifice and thermocouple regularly: Use a small brush to clean the pilot orifice and thermocouple of any sediment or debris that may accumulate.
- Check the gas supply and pressure regularly: Make sure the gas supply is turned on and the pressure is within the recommended range.
- Check the water heater’s temperature and pressure relief valve: Make sure the valve is functioning properly and not clogged with sediment or debris.
- Drain the water heater regularly: Drain the water heater every 6-12 months to remove sediment and debris that can accumulate and affect its performance.
Conclusion
If your water heater pilot light won’t stay lit, it can be frustrating and inconvenient. However, by troubleshooting the issue and performing some preventative maintenance, you may be able to resolve the problem yourself. Remember to check the gas supply, thermocouple, pilot orifice, spark generator, and pilot flame regularly to ensure your water heater is running smoothly and efficiently. If you’re not comfortable troubleshooting the issue yourself or if the problem persists after trying the above steps, it’s recommended to consult a professional plumber to resolve the issue.
Additional Tips and Resources
Here are some additional tips and resources to help you troubleshoot and maintain your water heater:
