Gas Furnace Pilot Light

Why Does My Gas Furnace Pilot Light Keep Going Out?

December 22, 2023

Few things are as concerning as waking up to a cold house during winter in Pigeon Forge, TN. One possible cause is that the pilot light went out. Here are several reasons your gas furnace pilot light keeps going out:

Draft or Wind

A draft or sudden wind near the furnace is a common reason for the pilot light to go out. Fortunately, the issue is easily fixed by sealing the drafts and closing the windows and doors.

Dirty Pilot Light Orifice

The pilot light orifice controls the gas flow to the pilot light. A dirty orifice can cause the flame to go out.

A professional must take the furnace apart to clean the orifice properly. Cleaning all the components involved with combustion is part of our annual maintenance service. Therefore, it’s important to schedule regular furnace maintenance to keep the pilot on burning safely.

Accumulated Debris

A pilot light needs enough oxygen to continue burning. When your furnace accumulates dust and dirt, the debris can wind up inside the intake valve. When this blocks the flow of air, the pilot light will go out.

Faulty Thermocouple

A thermocouple is a safety device that detects the presence of a pilot light. It shuts off the gas flow if none is present. A faulty or dirty thermocouple might not detect the flame and shut off the gas, causing the pilot light to go out.

Gas Valve

The gas valve delivers the gas necessary for keeping the pilot light on. If the gas valve is off, the pilot light also turns off.

A pilot light that cannot stay on leads to a cold, uncomfortable home in Pigeon Forge, TN. Luckily, our service technicians can quickly pinpoint and fix the problem. Contact LB Chase Mechanical to schedule a furnace repair today.
