Why Does the Pilot Light Go Out on Water Heater?
As plumbing company we have seen just about any water heater issue there could be. And as the homeowners ourselves we understand the frustration when the pilot light keeps extinguishing. In this article, we will discuss why does the pilot light go out on water heater and how you can handle it by yourself or with professional help, so that your water heater remains in perfect condition at all times.
How a Pilot Light Works
To understand why the pilot light keeps going out, it’s important to first understand how it functions. The pilot light is a small flame that ignites the gas burner when the water heater needs to heat water. This flame is vital for gas water heaters, because it provides the necessary spark to start the heating process. The pilot light is maintained by a small gas flow, and if it goes out, the water heater will stop to work, leaving you without hot water searching for the water heater repair.
The pilot light operates together with several components:
- Thermocouple is a safety device that senses the presence of the pilot light. If the pilot light extinguishes, the thermocouple shuts off the gas supply to prevent gas from leaking into your home.
- Gas control valve regulates the flow of gas to both the pilot light and the burner. Its job is to make sure that the correct amount of gas reaches the pilot light to keep it burning.
- Pilot orifice is a small opening where gas exits to maintain the pilot light. It must remain unobstructed for the pilot light to function properly.
Common Reasons Why the Pilot Light on a Water Heater Keeps Going Out
There are several reasons why your water heater pilot light keeps going out:
- Thermocouple issues: If the thermocouple is faulty or dirty, it can be the reason why does the pilot light go out on water heater.
- Drafts: Strong drafts can blow out the pilot light. This is common in basements or poorly ventilated areas.
- Dirty pilot tube: Dirt and debris can accumulate in the pilot tube. This is one way to the obstruction of gas flow and extinguishing the pilot light.
- Faulty gas regulator: If the gas regulator is malfunctioning, it may not supply enough gas to keep the pilot light lit.
- Pilot orifice clogging: This one can get clogged with dirt or debris.
Troubleshooting Pilot Light Problems
One thing is to understand why does the pilot light go out on water heater, another is to solve it. Here are several troubleshooting steps you can take:
- Check the thermocouple: As we mentioned, make sure it’s properly positioned and free of dirt. Gently clean it if necessary. If it’s bent or damaged, the only thing to do is to replace it.
- Inspect for drafts: Identify and seal sources of drafts near the water heater. You might need to install a draft shield or move the heater to a less windy location.
- Clean the pilot tube: Turn off the gas and carefully clean the pilot tube with a needle.
- Examine the gas regulator: If you don’t have a plumbing education, you might need a professional for this one.
- Clear the pilot orifice: Use a thin wire to clear any blockages in the pilot orifice.
- Inspect gas supply: Ensure there are no interruptions in the gas supply. Check for leaks or blockages in the gas line. If you suspect a gas leak, turn off the gas supply immediately and contact a professional.
- Check the flame: The pilot light should produce a strong, blue flame. A weak or yellow flame indicates a problem with the gas supply or the pilot light assembly.
