If your pilot won't stay lit on your fireplace, it's often due to a faulty thermocouple or dirty pilot tube. The thermocouple is a safety device that shuts off the gas if the pilot light goes out. When it's malfunctioning or the pilot tube is clogged, it can prevent the pilot from staying lit. Cleaning the pilot tube and checking the thermocouple's condition are good first steps. If these measures don't work, you may need to replace the thermocouple or consult a professional for further diagnostics and repair.
