If the sensor is clean and the flame is strong, look at the gas valve. Some models have a manual override or a “HI/LO” setting that can get stuck in an intermediate position. Toggle it firmly. Also, check if the fireplace is receiving power to its electronic ignition module—even ventless gas fireplaces often need a battery backup or a wall switch to activate the main burners.
Replace the batteries in the remote or wall receiver if you have one. Yes, even gas fireplaces can be picky about batteries. A dying AA battery can feel like a dead gas line. It’s the 2026 equivalent of “did you check the cable?”
