first post on this forum, so please excuse any newbie errors...
I have a gas fireplace at home that I haven't used in a couple of
years. I had turned the pilot off after I used it last. I tried to
start it back up yesterday, and the pilot started right up. I have a
wall switch that controls the gas flow and turns the fireplace on.
When I try to flip the switch to turn the fireplace on, it does
nothing 9 times out of 10. Occassionally the flames will come and
stay lit for a couple of minutes before going out again, and then
nothing. I don't smell any gas when the fireplace switch is on but
the flame isn't present. Not sure where to look to try and debug this
issue... any helpful pointers would be greatly appreciated!
Merry Christmas!
Funny thing......I just went through a very similar process with our
gas log set today.
I tried to light the pilot & it would light but not stay lit
So.... I turned off everything.....the electrical switch on the log
set (my set doens't have a wall switch), the manual valve on the log
set to "off" postion and the recessed gas cock on the side of the
fireplace.
I did the start up process....open gas cock, turn manual valve to
"pilot" & depress, light pilot and hold knob in for ~2 minutes, turn
manual valve to "on".
Pliot stayed lit......flipped electrical switch to "on" and the log
set fired up & has stayed burning for a few hours so far.
I have no idea why the pilot wouldn't stay lit but turning everything
off seems to have fixed it. ????
Give the "total shutdown and wait a few minutes before a re-start"
a try.

Does it have a thermocouple on the pilot a maybe 2" round metal piece
with a wire on it going to a gas valve, that might be bad I used a
propane torch to heat one up once, its probably a standard item even
some place like Sears might have for cheap. But I am guessing and dont
know if what I recomend is safe.
Thermocouple/thermopile assemblies have 2 separate circuits powered by
the their respective devices.
Thermocouple = 20 millivolts (+/-)
Thermopile = 750 millivolts (+/-)
If the pilot lights and stays lit, the problem isn't with the pilot circuit.
If the main burner doesn't light, the problem is in the main burner circuit.
Some units have more than 1 switch controlling them.
The supplied switches on the units are notoriously unreliable.
The gas valve generally has connections for the main burner labeled TH,
TP, and TH/TP. The main burner is operated by a switch that makes a
circuit between the TH and TH/TP connections.
Is there a remote installed on the fireplace? If so, there is usually a
switch on it labeled on/remote/ off. If you move the switch to on and
the main burner lights, check the batteries in both the remote and the
receiver. If it doesn't light, check the other switches/controls
connected to the above connections.
The above procedure assumes the control valve is in the "ON" position
and not in "PILOT".
I had two phone calls this week from people with gas fire places and heaters and
both had the same problem. DIRT!!!

Happy new year to all!
I checked the fireplace and couldn't figure out the make - the card
that came with it says XDVR-38RMN, but I couldn't find anything based
on that description in my Google search. I did see a circuit diagram
that mentions Thermopile. It's a masonry insert.
The pilot does light easily and stays lit, so as you suggested, that's
not where the issue is. I did clean everything out and then tried to
get the fireplace going again to no avail... There is NO remote with
the fireplace - just the wall switch. I checked all the circuit
breakers and saw no issue there. When I flip the wall switch, nothing
happens. I don't smell gas when I flip the switch... Would a bad
thermopile result in these symptoms?
Appreciate any additional pointers you may be able to offer.
Thanks!
