If you’ve been having problems with your water heater’s pilot light, you’re not alone. This issue is not uncommon, and it can be quite frustrating to deal with. Luckily, there are some simple solutions that you can try before calling in a professional. In this post, we’ll go over some common reasons for pilot light problems and provide solutions so that you can have hot water once again.
Reasons Why Your Water Heater Pilot Light Won’t Stay Lit
1. Dirty Thermocouple
A dirty thermocouple is a common reason why pilot lights go out. The thermocouple is a small sensor that sits next to the pilot light and detects when it’s on. If the thermocouple is dirty, it won’t register the pilot light’s flame, and the gas valve will shut off the gas supply, causing the pilot light to go out. To fix this, turn off the gas supply and clean the thermocouple with a piece of sandpaper or a wire brush.
2. Faulty Thermocouple
If cleaning the thermocouple doesn’t solve the problem, it could be faulty. A faulty thermocouple will need to be replaced. This is a job that should be done by a professional unless you have experience with water heater repair.
3. Clogged Pilot Tubing
Pilot tubing can become clogged with debris or spider webs. This can cause the pilot light to go out or prevent it from lighting at all. To fix this, turn off the gas supply and use compressed air to clear out the pilot tubing.
4. Gas Control Valve Issue
If the gas control valve is faulty, it won’t be able to maintain a constant gas supply, which can cause the pilot light to go out. This is a problem that will require professional repair or replacement.
5. Loose Pilot Light Fittings
If the fittings that hold the pilot light in place are loose, the pilot light won’t stay lit. To fix this, turn off the gas supply and tighten the fittings.
6. Low Gas Pressure
If the gas pressure is low, the pilot light may not stay lit. This is a problem that will require professional repair.
7. Air in the Gas Line
If there is air in the gas line, it may prevent the pilot light from staying lit. To fix this, turn off the gas supply and bleed the air from the line using the gas valve.
Q: How do I know if my thermocouple is working?
A: If the pilot light stays on, the thermocouple is working. If it goes out, the thermocouple may be dirty or faulty.
Q: Can I replace a thermocouple myself?
A: If you have experience with water heater repair, you may be able to replace a faulty thermocouple yourself. If not, it’s best to call in a professional.
Q: Should I try to fix the pilot light myself?
A: If you’re experienced with water heater repair, you can attempt to fix the problem yourself. However, if you’re unsure, it’s best to call in a professional.
Dealing with a water heater pilot light that won’t stay lit can be frustrating, but it’s usually a simple problem with a simple solution. By following the steps outlined above, you can troubleshoot and fix the issue without having to call in a professional. However, if you’re unsure or uncomfortable with water heater repair, don’t hesitate to reach out to a professional who can help.
