How to Relight the Pilot Light: A Comprehensive Guide
What is a Pilot Light?
A pilot light is a small flame or spark located at the base of gas appliances, such as stoves, furnaces, and water heaters. The pilot light ignites the fuel, allowing the appliance to burn efficiently and safely. Whenever the pilot light goes out, the appliance stops working, and you’re faced with a sudden lack of heat or hot water. In this article, we’ll explore how to relight the pilot light safely and effectively.
Why Relight Pilot Light?
• Safely restart the appliance’s operation
• Prevent unauthorized gas leaks
• Inspect the pilot light annually to detect any issues earlier
• Enhance boiler efficiency
Pre-lighting Check
Before starting the process, make sure you have the following checklist completed:
- Turn off the appliance: Move the burner switch or flame failure device to the OFF position.
- Disarm any smoke detectors.
- Identify the pilots: Check your appliance documentation or label for the position of the pilot lights and their shut-off valves or knobs.
Step 1: Remove Any Impediments
Remove the pilot light assembly or check valve by turning the retaining clip counterclockwise. (Note: For some brands, this might be under a decorative cap or requiring a small pin.)
| h Pilot Light Relighting – Step 1 | |
|---|---|
| Removable parts | Location(s) |
| Pilot assembly | Backside or behind a panel |
| Access panel | Underneath stovetop or hood |
| Small pin cap | Bottom of pilot lights |
Step 2: Clear Any Obstructed Fuel Path
Confirm the pilot orifice (#1) is **clear of any debris: Use a cable or cloth to investigate and remove any blockage.
| h Fuel Path Components | |
|---|---|
| Orifices (#1) | Pilot lights |
| Pilot orifices (#1) | Water heater connection |
| Sediment drain | Tank valve |
Step 3: Restore Gas Flow
Return the pilot orifice seal (if removed or damaged) to its designated position.
| Repair or Replacement
| Part | Repair or Replace? |
| Orifice or seal | If damaged – replace; otherwise, seal |
| Knob cover | Clean and reinstall knurled |
Step 4: Light Pilot Light
Holding down the pilot knob, while screwing inward, and maintain a reliable flame using the pilot control valve (usually by closing the knob to allow excess gas to vent). In some cases, a specialized tool, such as pilot light tester or ignite kit, can help simulate the ignition.

Right | Improper inclination | |
Down | Air intake issues | |
Step 5: Observe and Test
If the pilot light fails to relight again, try cleaning the following components:
- Purge any obstructions; clean pilot assembly or reassemble the fuel line(s).
- Verify safe gas supply.
In Conclusion
Relighting your pilot light can be as simple as removing any debris, restoring the gas flow, and manually igniting it. We’ve provided step-by-step guidance to simplify the process, including some critical components to assess. Don’t settle for lukewarm appliance performance – with this definitive guide, you’ll find yourself in a sparkling, functional pilot-powered world!
