72 views
Your gas fireplace shutting off after 10 minutes can be due to several issues like overheating, a malfunctioning thermocouple or thermopile, or an obstructed vent system. Overheating occurs when the fireplace exceeds safe temperature limits, causing the safety feature to shut it off. A faulty thermocouple or thermopile, which are safety sensors, can misread the temperature and prematurely turn off the gas. Lastly, an obstructed vent can lead to improper exhaust and air supply, triggering a shutdown. Consulting a professional for a thorough inspection is recommended to address the specific cause accurately.
