Common issues we resolve

Pilot light won’t stay lit (thermocouple/thermopile or dirty pilot)

A very common failure is a pilot that lights but goes out when you release the knob or soon after. Typical causes include a weak or dirty thermocouple/thermopile that can’t generate enough millivolts to hold the gas valve open, a clogged pilot orifice, or low/unstable gas supply. Symptoms include an intermittent or yellow, lazy pilot flame that doesn’t fully engulf the sensor. In Denver’s high altitude (~5,280 ft), appliances often need altitude-specific adjustments; improper derating can worsen these symptoms. A pro will clean/realign the pilot, test millivoltage, and replace a failed thermocouple/thermopile if needed.

No ignition/spark (defective igniter or misaligned electrode)

If you press the igniter and the pilot won’t light, the spark system may be at fault. Common issues include a failed piezo/electronic igniter, a misaligned or dirty spark electrode, or poor connections. Technicians verify spark at the electrode, correct the gap/alignment, clean carbon buildup, and replace faulty igniters as needed. For systems that use intermittent pilot ignition, confirming visible spark before lighting attempts is a key diagnostic step.

Excessive soot/blackened glass or logs (improper air‑fuel mix or log placement)

Black glass or sooty logs indicate incomplete combustion, often from too much gas and not enough air, clogged burner ports, or ceramic logs positioned incorrectly and impinging on the flame. Correcting the air shutter, cleaning burners, and restoring factory log placement typically resolves it. At Denver elevation, units that haven’t been properly high‑altitude derated can also run rich and soot more readily.

FAQs

Common questions

Why won’t my gas fireplace turn on?

Typical culprits include an extinguished pilot light, dead remote batteries or a tripped breaker, a closed gas shutoff valve, a dirty spark igniter or pilot assembly, clogged burner ports, or a weak/dirty thermocouple or thermopile that won’t allow the gas valve to open. Basic checks include confirming the gas valve is ON, replacing remote or receiver batteries, resetting the breaker, carefully relighting the pilot per your manual (purging air in the pilot tube can help after long inactivity), and gently cleaning the pilot/igniter area and burner ports. If it still won’t light, have a technician inspect the ignition and safety circuits before further use.

Why does my pilot light keep going out?

A pilot that won’t stay lit is often caused by a dirty or failing thermocouple/thermopile, a dirty or misaligned pilot orifice, drafts or downdrafts, low or unstable gas pressure, or an oxygen‑safety sensor/venting issue that shuts the gas off. Start by ensuring the pilot flame is clean, blue, and fully engulfing the thermocouple tip; eliminate nearby drafts; and have the pilot assembly cleaned and gas supply/pressures checked. Persistent outages should be evaluated by a pro to address safety controls and venting.

Why are my flames yellow and why is there soot on the glass or logs?

Yellow/orange flames and soot point to incomplete combustion—commonly from a dirty or clogged burner, improper air‑to‑fuel mix, blocked or improper venting, or ceramic logs that are out of position. At higher elevations like Denver, some gas fireplaces may also need manufacturer‑specified high‑altitude adjustments to maintain a proper mixture. Stop use if you see heavy soot or smell combustion odors, verify log placement per your manual, and schedule a professional cleaning and combustion check; also ensure working carbon monoxide detectors are installed on each level of the home.
