Fireplace clicks and shuts off when running
There are a few things that could be causing this problem. The most common resolution to this problem is making sure the thermo couple is screwed tight into the valve. While looking at the gas control valve, you'll see a few wires and small metal tubes going into it. The one you want to tighten is the tube that is copper. Even if you get only a half a turn on the little brass fitting that's holding it screwed in, that's usually enough. If that doesn't do the trick let me know and I'll get back to you with some other things to try.
My gas fireplace's pilot light is on-but when I
I had this exact problem.
Open the glass front. Take a piece of fine steel wool and clean the little metal ends where the flames ignite. Sometimes they just get gummed up. It prevents enough flow from getting through to maintain a flame.
How do you check a thermopile?
A thermcouple is what keeps pilot on, if your unit has both a thermocouple and thermopile then your pilot CAN stay lit and main burner not come on.do not buy a gas vavle untill you check the thermopile voltage!! very costy blunder.this is how you test it..( open circuit test) Disconnect thermopile leads from valve. take a volt meter set it to millivolts- set it to a mv reading above 500 so that you can test it correctly, my meter has 2000 setting and I use that. connect T/P leads to meter leads.. reading should be 500mv.
( closed circuit test) connect leads of meter to terminals that your thermostat or on/off swich are hooked too, usually top and bottom terminals on most gas valves, turn unit on and reading should be 150mv or more... you need try open circuit. I can test your vavle too if you like keep me posted if I helped or not. 15 yrs experience in gas repairs!!
