My gas fireplace pilot is lit but the main burner won't come on — what's wrong?
For Marshall's steep, tight-access hillside homes we plan the visit as carefully as the repair, then get to the likely cause: a worn thermopile or, given the damp French Broad gorge, a corroded connection in the millivolt circuit. Either leaves the pilot lit while the main burner stays cold, and both are inexpensive to put right.
Access first, then the fault
Marshall's downtown buildings stack narrow and multi-story against the mountainside, and the outlying homes sit on tight, steep lots up toward Walnut and the Mars Hill Road. That terrain shapes how we route the visit and stage parts, but the diagnosis is the same one we run everywhere: the pilot heats a thermopile that makes a few hundred millivolts, and that voltage is what opens the main valve. As the sensor ages it makes less, until it proves the pilot without firing the burner. We read it in seconds with a meter so a single trip up your hillside settles it.
Gorge damp works on the connections
The French Broad gorge keeps Marshall's evenings cool and damp, and that moisture oxidizes the low-voltage contacts — a corroded wall switch or wire terminal can strangle the signal exactly like a dead sensor. We trace the whole path before calling it. On the steepest Walnut and Mars Hill Road lots we stage the diagnosis so a single trip covers both the testing and the swap, because a second visit up these grades is time you shouldn't have to pay for. Marshall runs mixed-fuel, so on a propane home we also check the tank and regulator, since low LP pressure can starve the burner while the pilot holds.
Madison County, 25 minutes north
Repairing a gas valve or line is licensed work in North Carolina, not a handyman's job and never DIY. When a fix reaches the piping we pull the county permit and meet the inspector so the work is documented. We're 25 minutes north of the Asheville showroom. Call (828) 545-0525.
