Heat Thermocouple and Confirm Status — Turn the Gas Control to 'On'
Part of project
How to Relight a Gas Water Heater Pilot Light · Step 4 of 5
In this video
Once the pilot flame is lit, you must continue to hold the control knob down for approximately 30-60 seconds. This allows the flame to heat up the thermocouple. The heated thermocouple generates a small electrical voltage that signals to the gas valve that the pilot is lit and it is safe to stay open. On this Honeywell model, you will know the thermocouple is ready when the 'STATUS' light on the control valve begins to blink (typically red). Once the light blinks, you can safely release the control knob.
Goal: Ensure the pilot light remains lit after releasing the control knob.
- If you release the knob too soon, the pilot flame will go out, and you will need to repeat the ignition process.

FAQs
What are the crucial safety steps to take before and during relighting the pilot light?
Always ensure there's no smell of gas before you begin. If you smell gas, immediately turn off the main gas supply, ventilate the area thoroughly, and do not attempt to light anything; call a professional. Always work in a well-ventilated area.
My pilot light won't stay lit after I release the gas control knob. What should I do?
This often indicates a problem with the thermocouple, which is a safety device that senses the pilot flame. Try holding the gas control knob in for a full 60 seconds (or even 90 seconds) after lighting to ensure the thermocouple heats sufficiently. If it still won't stay lit, the thermocouple may be dirty or faulty and might need cleaning or replacement by a professional.
Do I need the exact "Scripto Aim-n-Flame Max Flex Utility Lighter" or will any long lighter work?
While the specific Scripto model is recommended for its flexibility and length, any long-nosed utility lighter designed for fireplaces or grills will work, as long as it allows you to safely reach the pilot light without getting too close to the flame. Avoid using short matches or standard lighters, as they pose a burn risk.
I'm having trouble locating the access panel or the pilot light itself. Where are they usually found?
Most gas water heaters have an access panel located at the bottom front of the unit, covering the burner and pilot assembly. For older models, you might need to remove an outer metal cover first. If you're still unsure, consult your water heater's owner's manual for exact diagrams and instructions specific to your model.
