How to fix a water heater pilot light
Gas water heaters are reliable appliances that provide continuous access to hot water in homes. However, if you find yourself without hot water, the cause may be a malfunctioning pilot light. In this article, we will explore how to independently check and potentially address this issue.
Step 1: Pilot Light Inspection
Most water heaters have a removable access panel at the bottom. Remove the panel to access the pilot light and reset switch.
Approach your gas water heater and locate the spot where a small flame – the pilot light – typically burns.
If the pilot light is not burning, it may be the reason for the lack of hot water.
Step 2: Restoring the Pilot Light.
- Switch the water heater to pilot mode.
- Depress the pilot button and hold it in that position.
- Wait approximately 30 seconds while continuing to hold the pilot button.
- Visually check whether the flame in the pilot light has ignited.
- If the flame has ignited, the problem was likely a momentary startup issue. Return the water heater to normal mode, and it should begin heating water.
If the flame does not ignite, proceed to the next step – the thermocouple may be faulty.
Step 3: Thermocouple Replacement
The thermocouple is a device responsible for maintaining the pilot light’s operation. If the pilot doesn’t start, the thermocouple may be defective. Replacing the thermocouple could resolve this issue.
- Disconnect the gas and power supply to the water heater.
- Remove the panel to access
- Disconnect the thermocouple from the gas control device.
- Purchase a new thermocouple compatible with your water heater.
- Connect the new thermocouple to the gas control device.
- Reinstall your burner.
- Reconnect the gas and power supply, then repeat the pilot light restoration procedure.
- Switch the water heater to pilot mode.
- Depress the pilot button and hold it in that position.
- Wait approximately 30 seconds while continuing to hold the pilot button.
- Visually check whether the flame in the pilot light has ignited.
The flame should light. Go back to “Step 2” above to make sure you did everything correctly.
If the issue persists after these steps, it is recommended to consult a professional for a more thorough diagnosis and repair of your gas water heater. Remember that safety should be a priority, and if you lack experience in repairing gas appliances, it is best to rely on professionals.

Alex was prompt, professional and friendly and didn’t make me feel bad that I had a very simple job I probably could have figured out myself. Great service. I’ll be back.Grace C2024-10-01This was the 3rd company I looked into for my plumbing issues. I was able to get a same day appointment and the technician Almaz arrived at the start of the 2-hour window they quoted. I even got a text that he was on his way. I had two pipe leaks, one under the bathroom sink and one in the crawl space. Almaz was careful and thorough in diagnosing the latter and worked his way down the tight crawl area. We ended up cutting out dry wall in my garage to get an actual quote. Their prices seem very fair and so far I’m very happy I went with them. Will update once the fix is complete.Laurie Frederick2024-09-30Excellent serviceman, Alex. Company receptionist and online/ texting to keep me (client) updated every step of the way.

I contacted United Plumbing and was able to get a service update within 30 minutes on a Sunday which was amazing. Alex came out and took care of the issue at hand swiftly and efficiently.
