Pilot Assembly Replacement in Humble, TX

A weak thermocouple leaves exactly that fingerprint. The pilot still lights, but the thermocouple no longer generates enough millivolt output to hold the gas valve's safety magnet open, so the instant you stop overriding it with the knob, the valve closes. Diagnosis is measurement, not guesswork: we meter the output, a healthy thermocouple reads around 25-30 mV open-circuit, and replace the failed proving part on the ignition you already have. For this specific symptom it is the most common fix in the book.

Scope. Pilot light installation builds an entire ignition system where nothing works; this service swaps a worn component out of the system you already own. Nothing about how the fireplace lights gets redesigned: the thermocouple, thermopile, igniter, or pilot hood that aged out simply gets replaced in place. When the architecture is sound and one part is dead, this is the correct service to book.

Evidence first, parts second. The dropout usually traces to the inexpensive proving part rather than the valve itself: a weak thermocouple explains most cases, the fix described here, while a valve magnet that fails to hold even on a healthy millivolt signal is the rarer culprit that genuinely calls for valve work. Our test sequence meters the thermocouple output and checks the valve's hold, after first ruling out a clogged orifice or a draft, so the part that gets replaced is the part that actually failed.

Four other suspects can produce the same symptom: a clogged pilot orifice, a draft that pulls the flame off the sensor tip, low gas pressure, or a valve magnet on its way out, and none of them care how new the thermocouple is. Our protocol re-reads the millivolt output after the swap and aims the flame so it fully envelops the sensor. Where the hood and orifice show wear too, the full hood-and-thermocouple assembly gets replaced instead of the single part.
