How to Fix a Gas Fireplace That Keeps Turning Off

WebThermopile laser power meters. A thermopile is simply an array of thermocouples connected in series and close together. The most common application is when a voltage is applied to cool one side of the thermopile and whatever it is bonded to. Thermopiles for laser power measurement, however, are used in the opposite fashion. WebIf it reads less, then the thermopile should be cleaned (turn off the gas supply and use a stainless-steel brush with fine-grit sandpaper), if the reading is still low, then replace the thermopile. Another reason your gas fireplace won’t stay lit could be the thermocouple. If you’ve tested the thermopile and it’s fine, with a reading of ...
