What is a common cause for a pilot light to go out?

A common cause for a pilot light to go out is strong drafts and poor ventilation. When there is an influx of outside air or a significant change in airflow in the vicinity of the pilot light, it can disrupt the flame's stability. Drafts may come from open windows, doors, or other openings, which can extinguish the pilot light. Additionally, inadequate ventilation can affect combustion processes, leading to irregular flame behavior and potential extinguishment.

In contrast, while excessive heat around the pilot area could negatively affect the pilot assembly, it is less commonly cited as a primary cause for the pilot light going out. Using a lighter instead of a match would not typically contribute to extinguishing the pilot light itself; it merely pertains to how the pilot is lit. Low gas pressure can indeed impact the pilot light's function but is not as direct a cause of it being blown out by environmental factors like drafts.
