Why does my gas fireplace's main burner light and then go out after a few seconds?
In Arden, this often shows up on the tired open masonry fireplaces of Royal Pines and Skyland, fitted with gas logs. The burner lights, then the thermopile can't hold the valve — and in a drafty 1980s firebox, cold air spilling past the pilot chills it enough that the sensor never makes the millivolts to keep the flame.
A drafty firebox starves the pilot
Arden's older open masonry fireplaces are famous for pulling heat out of the room, and that same draft washes across a standing pilot flame. When the pilot is being cooled or nudged off the thermopile tip, the sensor under-produces even when it's not worn out — so the valve won't latch and the burner drops seconds after it lights. On these homes the draft is frequently the hidden cause behind a healthy-looking part.
Where a sealed insert earns its place
We tell a lot of Skyland and Royal Pines homeowners the same thing: a sealed gas insert tames the draft that's been undermining the pilot and turns a heat-losing open firebox into a real heater that actually holds its flame. It's the honest fix for a fireplace that keeps dropping out, not an upsell — and we'll say so plainly.
Metered, permitted, fifteen minutes south
First we clean and reposition the pilot and read the thermopile open and under load to rule out a simple aged sensor or connection. Arden's on the gas main; we pull Buncombe County permits on gas work. We're 15 minutes south with parts on the truck. Call (828) 545-0525.
