How to Relight a Gas Water Heater Pilot Light: A Step-by-Step Guide
About This Project
1. **Access the pilot light:** Locate and remove the access panel near the bottom of the water heater, using a screwdriver if needed. 2. **Set the control knob to 'Pilot':** Turn the control knob to the 'Pilot' setting, sometimes requiring you to push it in while turning. Some models might have a dedicated red pilot ignition button. 3. **Light the pilot light:** While holding the control knob (or pressing the igniter button), ignite the pilot light with a match or long lighter. Hold the knob for 30-60 seconds after ignition to allow the thermocouple to heat. 4. **Turn the gas water heater on:** Once the pilot light stays lit, turn the control knob to 'On.' Verify the main burner ignites through the viewing window. 5. **Secure the water heater:** Reattach the access panel securely and check all connections for gas leaks. If any leaks are detected, shut off the gas supply immediately and contact the gas company or a qualified plumber.

Steps
Access Your Gas Water Heater's Pilot Light
5 minsLocate the access panel for the pilot light. It's usually a small metal panel near the bottom of the water heater. Carefully remove the panel to access the pilot light and burner assembly. You might need a screwdriver for some models; refer to your water heater's manual if necessary.
Watch: Access the Burner Assembly
Set the Water Heater Control Knob to 'Pilot'
2 minsTurn the control knob to the 'Pilot' setting. This may involve pushing the knob in while turning. Some models have a separate red button for pilot ignition. Consult your water heater's instruction manual for specific instructions if needed.
Watch: Attempt Standard Pilot Lighting Procedure
Light the Gas Water Heater Pilot
5 minsUsing a long lighter or match, carefully light the pilot light while holding down the control knob (or pressing the igniter button). Hold the knob down for 30-60 seconds after ignition to allow the thermocouple to heat up. If the pilot doesn't light, repeat the process and check for obstructions.
Watch: Light Pilot Light
Turn the Gas Water Heater On
1 minOnce the pilot light remains lit after releasing the control knob, turn the knob to the 'On' setting. Check for the main burner ignition through the viewing window. If the main burner fails to ignite, refer to your water heater's manual for troubleshooting.

Common Problems
Safety concern: If you smell gas at any point, immediately turn off the gas supply to the water heater and ventilate the area. Contact your gas company or a qualified plumber.
Solution: Take proper safety precautions. If you smell gas at any point, immediately turn off the gas supply to the water heater and ventilate the area. Contact your gas company or a qualified plumber.
Prevention: Always follow safety guidelines before starting the project.
Ensure power to the water heater is turned off at the circuit breaker before removing the panels.
Solution: To avoid this issue: Be mindful of this warning and take appropriate precautions.
Pilot flame is hard to see, making verification difficult.
Solution: This step is optional but highly recommended as it makes verifying the pilot flame much easier.
Handle the control knob gently to avoid damage.
Solution: To avoid this issue: Be mindful of this warning and take appropriate precautions.
Lost screws can prevent pilot light reassembly.
Solution: Keep the small screws in a safe place so they are not lost.
Gas leaks are extremely dangerous. Do not use an open flame to check for leaks. If you smell gas, shut off the supply immediately, ventilate the area, and call a professional.

Frequently Asked Questions
What should I do immediately if I smell gas at any point during this relighting process?
If you detect any gas odor, stop immediately. Turn off the main gas supply valve to your water heater and evacuate the area. Do not attempt to continue the relighting process, and contact your gas company or a qualified plumber for professional assistance to locate and fix the leak.
I've lit the pilot, but it goes out as soon as I release the control knob. What's the problem?
This common issue typically points to a faulty or insufficiently heated thermocouple. Try holding the control knob in for the full 60 seconds (or even a little longer) to ensure the thermocouple has enough time to heat up. If the pilot still won't stay lit, the thermocouple may be dirty, misaligned, or need to be replaced.
Do I need the specific Husky screwdriver and Scripto lighter mentioned, or can I use different tools?
No, the specific brands mentioned are just examples. Any standard Phillips or flathead screwdriver that fits your water heater's access panel screws will work. For lighting the pilot, any long-reach lighter, such as a BBQ lighter or even a long wooden match, is suitable.
The project is marked 'beginner' and '45 minutes,' but I'm finding it difficult or it's taking much longer. What should I do?
The difficulty and time estimates are averages; it's perfectly fine if it takes you longer, especially if it's your first time. If you're struggling with any step, feel unsafe, or simply can't get the pilot to light after several attempts, don't hesitate to pause and call a qualified plumber for assistance. Safety is paramount.
My pilot light is on and strong, but the main burner isn't igniting when I turn the control knob to 'On.' What could be wrong?
First, ensure your water heater's thermostat is set to a temperature that requires heating. If the thermostat is set correctly and the pilot is still robust, there might be an issue with the main gas valve or the thermostat itself, preventing gas from flowing to the burner. This situation usually requires a professional diagnosis.
How can I help prevent my gas water heater pilot light from going out again in the future?
Pilot lights often go out due to drafts or a failing thermocouple. Check for air drafts around your water heater and ensure the exhaust vent system isn't blocked. Regular, gentle cleaning around the thermocouple can also improve reliability. If it frequently goes out, consider replacing the thermocouple.
