No Hot Water? Your Pilot Light Might Be to Blame
If your water heater pilot light won’t stay lit, you’re likely dealing with a frustrating issue that disrupts your hot water supply. At Neighborhood Plumbing, we help homeowners across Salt Lake City, Sandy, Ogden, Layton, Draper, and Bountiful get back to reliable hot water fast using safe and effective fixes.
Common Reasons the Pilot Light Keeps Going Out
Understanding the cause helps determine the right fix:
- Dirty thermocouple: If the pilot flame doesn’t reach or heat the sensor, it will shut down.
- Faulty pilot tube: Blockages or buildup can weaken the flame.
- Gas supply issues: Low gas pressure or a faulty control valve may prevent a consistent pilot.
- Vent or flue problems: Poor ventilation can cause flame displacement or extinguish the light.
- Faulty control valve: If the safety shutoff component is failing, the pilot light won’t stay lit reliably.
How to Troubleshoot “Pilot Light Won’t Stay Lit”
- Turn off the gas: Always start safely by turning off the gas supply.
- Clean the thermocouple and pilot tube: Remove dirt or soot gently.
- Try relighting the pilot: Follow your manufacturer’s instructions precisely.
- Test the gas control valve: If it doesn’t supply consistent gas, replacement may be needed.
- Check for venting issues: Make sure flues aren’t blocked or improperly installed.
If these steps don’t work—or if you’re uncomfortable inspecting your gas components—it’s time to call a licensed plumber.

FAQs
What should I do when my water heater pilot light won’t stay lit?
If your water heater pilot light won’t stay lit, start by checking for drafts, dirt in the pilot tube, or a faulty thermocouple. Make sure the gas valve is open and the area is well-ventilated. If you’re not comfortable troubleshooting gas appliances, it’s safest to call a licensed plumber to inspect and repair your unit.
How can I tell if my thermocouple is bad?
A bad thermocouple won’t sense the flame and will shut off the gas supply, causing the pilot light to go out repeatedly. Signs include a pilot light that won’t stay lit or a flame that’s weak or flickering. Testing with a multimeter can confirm if the thermocouple is faulty, but if you’re unsure, it’s best to have it inspected professionally.
Why does my pilot light go out as soon as I release the pilot button?
This is a common sign that the thermocouple isn’t working properly. If the thermocouple can’t detect the flame, it shuts off the gas flow for safety. It may be misaligned, dirty, or worn out and in need of replacement.
How do I clean a thermocouple on a water heater?
To clean a thermocouple, first turn off the gas and remove the thermocouple from the burner assembly. Use fine-grit sandpaper or emery cloth to gently remove any soot or corrosion buildup. Reinstall the thermocouple and test the pilot light again. Regular maintenance can help extend the life of your water heater components.
How do I unclog a thermocouple?
Technically, thermocouples don’t “clog,” but carbon buildup or corrosion can interfere with performance. Cleaning the metal tip as mentioned above usually resolves the issue. If the thermocouple is still not functioning after cleaning, replacing it may be the most effective solution.
