Check the Thermocouple
If your pilot light won’t stay alight, it might be the thermocouple. Sometimes dust buildup collects on the thermocouple and blocks the sensor. Try cleaning the thermocouple and then relighting the pilot light. If it continues to go out, the thermocouple might need to be replaced.
Likewise, can I manually light my gas water heater?
If your hot water heater is a manual, grab a long lighter. After removing the metal plate covering the pilot button, scan the interior and find the pipe or pipes that lead up to the burner. Turn the pilot dial to the off position and wait 5-10 minutes for any gas to dissipate.

How do I know if my thermocouple is broken?
If you can’t get the flame to light at all, and you’re sure the gas is on, there’s probably an obstruction in the pilot tube. If the flame lights and goes out when you release the gas control knob after holding it in for the recommended 20 to 30 seconds, that’s the sign of a thermocouple malfunction.
How do you clean a thermocouple on a water heater?

How much does it cost to replace thermocouple?
1 cause of pilot lights that won’t stay lit is a worn-out thermocouple. It’s easy to replace and a new one costs $5 to $10. Rather than trying to unfasten the thermocouple inside the water heater’s burning chamber, it’s easier to remove the whole burner and thermocouple assembly.
What do you do if your water heater pilot light won’t light?
If the pilot doesn’t relight, if it goes out right after lighting or if it goes out repeatedly, by far the most common cause is a bad thermocouple. The good news: You can usually replace a thermocouple for minimal cost and in less than an hour.
