What is it

Pilot Assembly Replacement in San Antonio

Pilot assembly replacement swaps the full pilot unit — pilot hood, thermocouple/thermopile, and igniter — when the pilot won't stay lit. It's the most common fix for a gas fireplace that lights then dies.

Why this matters in San Antonio

San Antonio spans some of the oldest masonry in Texas — King William, Monte Vista, Alamo Heights — to vast new-build like Alamo Ranch and Stone Oak. Historic clay-liner cracking and masonry repointing dominate the older stock, while prefab cap-and-chase work leads in the suburbs. That local stock is exactly why our San Antonio crews tailor pilot assembly replacement to the homes here — not a generic checklist.

Common signs in San Antonio homes

  • Pilot lights but goes out when you release the knob
  • Weak, yellow, or wandering pilot flame
  • Igniter clicks but won't catch
  • Thermocouple/thermopile reads low

Pilot Assembly Replacement in San Antonio (Bexar County) — what's local

San Antonio sits in Bexar County (county seat: San Antonio). San Antonio's home county — some of the oldest masonry in Texas; clay-liner cracking and repointing dominate alongside suburban prefab work. For pilot assembly replacement that means our San Antonio crew sizes up the local housing stock before quoting — and follows Bexar County permit requirements for any work that needs an inspection sign-off.

Questions, answered

Pilot Assembly Replacement in San Antonio — FAQ

How do I know the assembly needs replacing, not just cleaning?

If the pilot won't hold after the orifice is cleaned, the flame is weak or lifting off, or the igniter sparks but the gas never catches, the thermocouple or pilot hood is usually shot. A tech measures thermocouple millivolt output (a healthy one reads around 25-30 mV open-circuit) to confirm before quoting a full swap.

Can I replace a pilot assembly myself?

It's not advisable. The assembly connects to the gas line and the safety shut-off circuit, and the pilot flame has to be aimed precisely at the thermocouple or the valve won't stay open. A licensed tech also leak-tests the connections afterward, which a DIY swap usually skips. Parts cost varies a lot by appliance model.

How long does a new pilot assembly last?

A thermocouple typically lasts 5-10 years; the igniter and orifice often outlast it. Soot, drafts, LP gas impurities, and a flame that's slightly mis-aimed all shorten thermocouple life. An annual check catches a weakening thermocouple before it strands you on a cold night.

Why does my pilot keep dying even with a new thermocouple?

A fresh thermocouple won't fix a clogged pilot orifice, a draft pulling the flame off the sensor tip, low gas pressure, or a failing valve magnet. That's why a tech checks flame envelope and inlet pressure rather than just swapping the part, and replaces the full assembly when the hood and orifice are also worn.
