Why Would Pilot Light Go Out on Water Heater?
The pilot light on a water heater is a crucial component that ensures the appliance is functioning properly. However, it’s not uncommon for the pilot light to go out, leaving you without hot water. In this article, we’ll explore the reasons why the pilot light might go out on your water heater and what you can do to prevent it.
Common Causes of Pilot Light Failure
Before we dive into the reasons why the pilot light might go out, it’s essential to understand the common causes of pilot light failure. Here are some of the most common reasons:
• Dirty or clogged pilot orifice: The pilot orifice is a small opening that allows the pilot light to burn. If it’s dirty or clogged, it can prevent the pilot light from igniting or staying lit.
• Incorrect gas pressure: If the gas pressure is too low or too high, it can affect the pilot light’s ability to burn properly.
• Faulty thermocouple: The thermocouple is a sensor that detects the pilot light’s flame and sends an electrical signal to the gas valve to open. If it’s faulty, the pilot light may not stay lit.
• Improperly installed or maintained pilot light: If the pilot light is not installed or maintained correctly, it can lead to frequent failures.
Why Would Pilot Light Go Out on Water Heater?
Now that we’ve covered the common causes of pilot light failure, let’s dive into the specific reasons why the pilot light might go out on your water heater. Here are some of the most common reasons:
1. Dirty or clogged pilot orifice****
A dirty or clogged pilot orifice is one of the most common reasons why the pilot light goes out on a water heater. The pilot orifice is a small opening that allows the pilot light to burn, and if it’s dirty or clogged, it can prevent the pilot light from igniting or staying lit. Regular cleaning of the pilot orifice can help prevent this issue.
2. Incorrect gas pressure****
Incorrect gas pressure is another common reason why the pilot light goes out on a water heater. If the gas pressure is too low or too high, it can affect the pilot light’s ability to burn properly. Checking and adjusting the gas pressure can help resolve this issue.
3. Faulty thermocouple****
A faulty thermocouple is another common reason why the pilot light goes out on a water heater. The thermocouple is a sensor that detects the pilot light’s flame and sends an electrical signal to the gas valve to open. If it’s faulty, the pilot light may not stay lit. Replacing the thermocouple can help resolve this issue.
4. Improperly installed or maintained pilot light****
An improperly installed or maintained pilot light is another common reason why the pilot light goes out on a water heater. If the pilot light is not installed or maintained correctly, it can lead to frequent failures. Following the manufacturer’s instructions for installation and maintenance can help prevent this issue.
5. Water heater not properly sized for the home****
If the water heater is not properly sized for the home, it can lead to frequent pilot light failures. A water heater that is too small for the home may not be able to produce enough hot water, leading to pilot light failures. Sizing the water heater correctly can help prevent this issue.
6. Leaks in the water heater****
Leaks in the water heater can also cause the pilot light to go out. If there is a leak in the water heater, it can cause the pilot light to extinguish. Checking for leaks and repairing them promptly can help prevent this issue.
7. Age of the water heater****
The age of the water heater can also affect the pilot light’s performance. Older water heaters may have worn-out components that can cause the pilot light to go out. Replacing the water heater may be necessary if it’s old or has reached the end of its lifespan.
Conclusion
In conclusion, there are several reasons why the pilot light might go out on your water heater. Regular maintenance, correct installation, and proper sizing can help prevent pilot light failures. If you’re experiencing frequent pilot light failures, it’s essential to identify the cause and take corrective action to prevent further issues.
