Why does my gas fireplace's main burner light and then go out after a few seconds?
In Canton, a fireplace that lights then dies deserves a closer look than most — this is a mill town where Pigeon River flooding water-damaged plenty of hearths and gas appliances. A weak thermopile is the common cause everywhere, but here we also check for flood-corroded valve terminals and connections that quietly bleed the voltage away.
Flood exposure changes the checklist
After the Pigeon River valley took on water, gas valves, pilot assemblies, and low-voltage connections in a lot of Canton homes were left corroded or contaminated in ways you can't always see. A thermopile that can't hold the valve open is the textbook cause of a burner dropping out in seconds — but a flood-touched valve or oxidized spade connectors produce the exact same symptom, and one of those is a safety matter, not just a comfort one.
We inspect the gas side, not just the sensor
On any home that saw water, we don't stop at metering the thermopile open and under load — we inspect the gas connections and valve for corrosion and integrity before we sign off, because a damaged valve is not something to nurse along. Canton is mixed-fuel; propane units get the added pilot-orifice and pressure check. We pull Haywood County permits on gas work and pressure-test what we touch.
Twenty minutes west, done right
Valley-floor fog and dampness rust dampers and caps early here, so corrosion is a recurring theme in Canton fireplaces. Gas repair isn't a DIY job in North Carolina — especially on a flood-exposed system. We're 20 minutes west with parts on the truck. Call (828) 545-0525.
