Easy Ways to Re-Light a Water Heater Pilot Light

When you step into the shower, you know the water will get nice and hot within a few seconds. If an icy deluge greets you instead, you know something’s not right. The typical reason behind this unpleasant, chilly surprise is a water heater pilot light that’s gone out.

Don’t worry—relighting the pilot doesn’t require specialized skills. Follow the quick, step-by-step plan from the pros at Service Experts Heating, Air Conditioning & Plumbing outlined below, and you’ll soon be back to delighting in those hot showers.

Steps to Light a Water Heater Pilot Light

To start out, read the user’s manual for your water heater model. Instructions differ from brand to brand, and you should get all the details you need in the manual. If you can’t find the printed copy that came with the unit, look up the model number online to find a digital version. However, the following steps should apply for many gas water heaters:

1. Find the gas shut-off valve, which typically is distinctly marked on the lower front part of your water heater. Turn this knob to the “Off” position and wait for five to 10 minutes to allow any lingering gas to dissipate.
2. Open the pilot light access cover or door, which is usually positioned under the gas valve. Sometimes, there isn’t a door; instead, you could possibly see the pilot light burner by peering into a small opening.
3. Arm yourself with a flashlight or headlamp. Then, peer into the pilot light access and locate two small gas tubes leading to the burner. Keep an eye on this part of your water heater as you go ahead with lighting the water heater pilot.
4. Switch the gas knob to “Pilot.” This action lets the gas flow, readying the pilot light for ignition. Some units have a designated red button for pilot mode, which you should press and hold.
5. Light the pilot light while still holding down the gas knob or button. The water heater could have an igniter button, frequently red or black. If it doesn’t, you’ll need a long lighter to light the pilot by hand.
6. Push down the gas knob or button for about 30 to 60 seconds after the flame sparks. Be certain the flame remains lit. 
7. Rotate the gas knob to “On.” You should hear a whump or whoosh sound as the main burner ignites and your water heater comes back to life.
8. Replace the access cover or door. Give your water heater approximately 20 to 60 minutes to reheat the water, and you’ll be all set to enjoy that hot shower!

a Pilot Light Won’t Stay Lit?

Needing to relight the pilot every once in a while isn’t a cause for concern. But, there could be a more severe underlying issue if the water heater pilot light won’t stay lit. Some frequent causes of this are:

• Dirty thermocouple: The thermocouple is an automatic safety shut-off, stopping gas flow when the pilot light isn’t on. If this element is misaligned, dirty or damaged, you may face frequent pilot light issues. Reposition the thermocouple slightly and try lighting the pilot a second time. If that doesn’t work, you may need to clean it. And if that proves fruitless, it might be necessary to replace the thermocouple, an easy task for a professional technician.
• Dirty pilot opening: If your pilot light gives off a yellow flame, it’s likely due to a dirty pilot opening. This can hinder the thermocouple’s functioning, leading to pilot light instability.
• Weak or faulty gas regulator: Trouble with this component might lead to an inadequate gas supply needed to maintain the pilot light. If several gas appliances in your dwelling have similar problems, examine the regulator.
• Gusty conditions: Water heaters often share a utility closet with the furnace, which demands fresh air to operate properly. Powerful drafts from this air intake can blow out the pilot light.
