It is relatively common for an older furnace pilot light to go out occasionally due to various environmental and mechanical factors, though it should not happen on a frequent, daily basis. Common causes for a pilot light extinguishing include strong drafts blowing down the flue or through the utility room, a buildup of dust, lint, or soot around the pilot orifice that disrupts the steady flow of gas, or a deteriorating thermocouple that fails to maintain a reliable electrical signal. Additionally, minor gas pressure fluctuations from the utility provider can cause the flame to flicker and die. However, if your pilot light goes out repeatedly every few days or weeks, it indicates an underlying mechanical problem, such as a faulty thermocouple or a drafting issue. You can verify system stability when the pilot stays lit reliably for extended periods.
