  • A dirty thermocouple

Troubleshooting The Pilot Light Not Staying Lit Problem

  • You will have to check if the gas supply to the water heater is uninterrupted. Make sure the gas valve is fully open and that there are no obstructions in the gas line.
  • The thermocouple is a safety device that senses the pilot light’s flame. If it detects that the flame is out it automatically shuts off the gas supply to prevent gas leaks.
  • Over time the thermocouple can wear out or become dirty and thus causing it to malfunction. Cleaning or replacing the thermocouple should resolve the issue and ensure that the pilot light stays lit.
