My Gas Fireplace Goes Out. The gas technician suggested replacing the pilot burner/igniter/thermocouple. Also, if your main burner will run for a while, then go out, make sure your pilot stays lit.
I recently purchased a home that has a gas fireplace. After it goes out and i attempt to relight it the burners will only stay lit for about 5 mins. My gas fireplace won't light. If both the main flame and the pilot go out, the problem is likely on the side of the since the switch is delaing with millivolts, even a small amount of resistance is enough to essentially shut off the fireplace, just as if you'd turned it off at the.
One hvac guy told me he never leaves the pilot going, because it does use some amount of gas.
