My gas fireplace pilot is lit but the main burner won't come on — what's wrong?
At Waynesville's 2,650-foot elevation your fireplace works a heating season roughly three weeks longer than Asheville's, and that steady duty is exactly what wears out a thermopile — the pilot-heated sensor that makes the voltage your main valve needs. A lit pilot with a dead burner is its classic failure, and usually a quick, low-cost swap.
A longer season is harder on the sensor
Waynesville and Hazelwood homes lean on their hearths more than most of Western North Carolina — you run 10 to 15 degrees colder than the lower valleys, and the fireplace burns from early fall well into spring. Every cycle heats and cools the thermopile, and over the years its output drifts steadily downward. Eventually it still throws enough millivolts to keep the pilot proved but not enough to pull the main valve open when you call for flame. That gap is the exact fingerprint of your symptom, and at this elevation it tends to show up a few years sooner than it does down in town.
Natural gas or propane, set correctly
Waynesville runs mixed: some Frog Level and downtown homes tie into the gas main, while Hazelwood slopes and outlying cabins burn propane. The fuel matters, because propane and natural gas need different orifices and pressures, and a unit set for the wrong one will soot and stumble in ways that imitate a burner fault. On a propane home we also check the tank level and regulator, coordinating with your supplier, since low LP pressure can starve a main burner even when the pilot looks perfect.
Haywood County, one accountable call
Gas-valve and gas-line repairs are licensed work in North Carolina — a mason or handyman legally cannot make that connection, and we will not hand out DIY steps for it. If the fix reaches the gas piping, we pull the Haywood County permit and meet the inspector. We are 35 minutes west with the common thermopiles, switches, and receivers on the truck, so most Waynesville repairs close in one trip. Call (828) 545-0525.
