Why does my gas fireplace's main burner light and then go out after a few seconds?
In Weaverville, the answer depends on how new your fireplace is. Older downtown homes tend to run standing-pilot gas, where a burner that lights and quits means a weak thermopile can't hold the valve. The fast-growing Reems Creek builds usually have electronic ignition, where the same symptom points to a flame sensor or module instead.
New construction versus the old downtown
Weaverville is splitting into two housing worlds. In the original homes around the old downtown, a standing pilot keeps a thermopile warm enough to generate the millivolts that hold the gas valve open — and after enough winters, or after a summer that let the pilot clog and shrink, that thermopile under-produces and the flame drops seconds after it catches. It's a classic, inexpensive, single-visit fix.
The Reems Creek electronic-ignition units
The newer builds out Reems Creek and Ox Creek mostly use electronic ignition — no standing pilot at all. When one of those lights and immediately quits, we're looking at the flame-sense rod that proves the burner lit, a weak set of backup batteries, or the ignition module, not a thermopile. Knowing which system you have before we arrive saves you time and money, so tell us the brand when you call.
