Why Won’t My Furnace Pilot Light in Bethel Park, PA, Stay Ignited?

Dealing with a malfunctioning furnace during the winter in Bethel Park, PA, is a headache no homeowner wants. A faulty pilot light is a common furnace issue that people deal with, but its causes can vary. Here are some reasons your furnace pilot light won’t stay lit:

Faulty Thermocouple

The thermocouple is a safety device that senses heat from the pilot light. If the thermocouple doesn’t detect any heat, it shuts off the gas supply to prevent a leak. Scheduling regular maintenance will help you spot any issues with your thermocouple before they become too serious and cause your furnace to stop working altogether.

Dirty Furnace Pilot Light Orifice

Gas flows through an orifice within your pilot light before igniting. If this orifice clogs with dirt, the pilot light flame may dwindle to such a low level that the thermocouple can no longer detect it.

Gas Line Concerns

Issues with the gas line are another reason your pilot light won’t stay on. A faulty gas valve is another component to check if you have a full gas supply flowing into your home.

Drafts or Ventilation Issues

If there’s a draft near your furnace, the breeze can blow out the pilot light. Poor ventilation is another factor that can cause your pilot light to go out. Make sure that your furnace is clear of any large obstacles and that there are no drafts in the immediate area of the pilot light.
