What are some reasons for the pilot light on my water heater to keep going out?
What should I do if the thermocouple is faulty or dirty?
If the thermocouple is dirty, you can try cleaning it with a fine-grit sandpaper. If that doesn't help, you may need to replace the thermocouple entirely. It's also possible that the pilot light assembly itself is faulty and needs to be replaced.
