How to Fix Pilot Light on Boiler
Follow these steps to successfully relight the pilot light on your boiler:
Required Tools and Materials
- Long lighter or match
- Flashlight
- Wrench (if needed)
- Vacuum or brush for cleaning
Safety Precautions
Warning
- Ensure the gas supply is turned off before starting.
- Wait for at least 5 minutes after turning off the gas to avoid gas buildup.
- Do not use any open flames near the boiler until you are sure the gas has cleared.
Steps to Fix the Pilot Light
- Locate the Pilot Light: Find the pilot light assembly on your boiler. It is usually near the bottom of the unit.
- Turn Off the Gas: Locate the gas valve and turn it to the "Off" position.
- Wait for the Gas to Clear: Allow at least 5 minutes for any residual gas to dissipate.
- Access the Pilot Light: Remove any covers or panels to access the pilot light. Use a flashlight if necessary.
- Clean the Pilot Assembly: Check for dirt or debris. Use a vacuum or brush to clean the area around the pilot light and orifice.
- Relight the Pilot Light: Turn the gas valve back to the "On" position. Press the reset button (if available) and use a long lighter or match to ignite the pilot light while holding down the reset button for about 30 seconds.
- Check the Flame: The flame should be blue and stable. If it is yellow or flickering, there may be a problem with the gas supply or the pilot assembly.
- Reassemble the Boiler: Once the pilot light is lit and stable, replace any covers or panels you removed earlier.
Troubleshooting
If the pilot light does not stay lit after following these steps, consider the following:
- Check for drafts that could extinguish the flame.
- Inspect the thermocouple for damage; it may need replacement.
- Ensure the gas supply is consistent and not interrupted.
