Ventless Gas Fireplace Not Lighting but Pilot Is On

Ventless Gas Fireplace Not Lighting but Pilot Is Onの注目ポイントを分かりやすくまとめてご紹介します。

Check the thermopile and thermocouple. Over a season of sitting idle, these little metal rods can collect dust, pet hair, or a fine film of cooking grease. Even a speck of debris can insulate them from the heat. Gently clean them with a soft brush or compressed air—no steel wool, please.

While you’re at it, inspect the pilot flame itself. It should be a crisp, blue cone, about half an inch tall, wrapping around the sensor. If it’s lazy, orange, or sputtering, the gas orifice might be clogged. A can of compressed air aimed at the pilot assembly can work wonders, but avoid blowing directly into the gas line.

Practical Tip: The “Q-Tip” Test

If you can’t see the sensor clearly, use a clean, dry cotton swab to gently wipe it. If the swab comes away black or grey, you’ve found your issue. Do not use alcohol or cleaners—they can leave a residue that burns off unevenly. Dry cleaning is the name of the game.
