Why does my gas fireplace shut off by itself after a few minutes?
In Canton this symptom deserves an extra look, because Pigeon River valley flooding has left water-damaged gas fireplaces and controls throughout town. A shut-off minutes after lighting can be the usual weak pilot and thermocouple — or a corroded valve, control, or connection that took on moisture and no longer holds a steady signal.
Flood-touched gas connections need eyes on them
Any fireplace or gas appliance that saw floodwater should have its gas connections inspected before you trust it again. Corrosion inside a valve or at the thermocouple junction produces exactly this lights-then-cuts-out behavior, and on a fuel system that's a safety matter, not a nuisance to live with. Inspecting and verifying those connections is licensed gas work — the kind a mason or handyman legally can't touch.
Valley fog rusts the rest
Even well away from the flood line, Canton's valley-floor morning fog and dampness rust dampers and caps and corrode sensor connections earlier than you'd expect at this elevation. Haywood County runs both natural gas and propane, so on an LP setup add a regulator and tank-pressure check on the coldest nights, when propane is slowest to vaporize. The point either way is a strong, clean pilot holding a solid signal.
