I've had a gas fireplace for about 5 years in my master bedroom and it has worked fine ... until recently.
The problem is that when I turn the fireplace on (via a switch on the wall), the fireplace fires up and all is good. Then after about 4 minutes both the fireplace flame and the pilot light kick off. I relight the pilot light and the same thing happens after a few minutes of turning the flame on.
I had a service man come out and he fiddled with it for a couple of hours. He replaced the millivolt generator (G01A-332), but the problem still occurs. He seemed perplexed. He offerred to replace the gas valve but said it would cost $XXX.
Does anyone have any ideas on what I should check. I've checked all the wires and don't think the connections are bad.
I measured the voltage being generated by the millivolt generator. With just the pilot flame, it reads 555mv. When the main burner kicks on, it drops to 279mv. Is it supposed to drop down when the main burner kicks on?
