My gas fireplace's pilot light is on-but when I turn on the electric switch the fireplace will not light all the time. Sometimes it may take 2-3 minutes before it lights up but then goes out after 30 seconds with the pilot light still burning ---sometimes it doesn't light at all. Any suggestions?

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.

Hi,
Thr thing you need to do is take the pilot assembly all apart and blow the dust and dirt out of it.
After burning for many, many hours the air that is move up through the pilot assembly leaves dust and dirt which plugs off a bit of the air and makes the flame run rich. Meaning that it does not get enough air mixed in for complete combustion.
When you clean it you will see the dirt and dust com out of it.
Reassemble carefully just as you took it apart and it will be back to working great again!!

I hope that this will help you to solve your problem!

Thanks for using Fixya!!

Check for how clean the bottom of the unit is. I know it seems small but when dealing with these amounts of electric current they are just that "small" and the dust can be shorting out the unit and not allowing the gas valve to release the gas. Its a safety thing, they dont want gas around an electrical short "go figure" lol
