The Pilot Light on My Gas Furnace Went Out. What Should I Do?

Posted: December 9, 2016


One of the most common reasons your heating systems stops working is because the pilot light on your furnace goes out.

Pilot light failure is a lot more common on older furnaces – mostly because many of today’s higher efficiency furnaces have replaced pilot lights with electronic ignitions.

A pilot light can go out for several reasons, including:

  1. Clogged intake valves – Dirt buildup can make it difficult for the pilot light flame to “breathe.”
  2. A leak in your heating system – If your furnace detects a leak, your pilot light will shut off automatically for safety reasons.
  3. A broken thermocouple – A thermocouple is an electronic safety measure that cuts off gas supply in the event of a sudden temperature drop (if your thermocouple is damaged, it must be repaired or replaced by a professional).
