yes, I know the brown wire goes to the wall switch, but where does it hook up to the fireplace. Make sure those connections are good. As for calling a professional, look up your closest fireplace dealer. some brand names you can look up for the dealers are, Heat n Glo, Monesson, Superior, Peterson...etc. Just look up those for a dealer near you and call them for service, alot of dealers will service other brands.
Which one is the smart valve? Is it the honeywell one that with the on/off button?
Ya, they are well known for being junk, it may have died awhile ago and they didn't say anything. They also won't open the pilot valve if the ignitor is bad, just call someone and have them make sure it's safe and cleaned up
So that being said should I just replace it? I figure if I'm going to have someone come to "look" at it will be at least 100 buck, how much does the part cost?
You can't just replace it and think it will work, I'm just taking a wild guess based on a part that has had issues, it dosen't mean its bad. You need one special tool to change the gas valve that insures its safely operating, you should not change it it's not worth your family's safety.
This has already gone beyond this forum and getting towards DIY. Unfortunately, you really need to get a qualified professional to inspect and service it. We can not give you step by step DIY advice on this forum. You need to find the rating plate indicating the mfr., model and serial # then use this to locate a pro. FYI, in a typical Intermittent Pilot Ignition, turning on the switch energizes the control causing sparking at the pilot and gas flow only to the pilot. Within a second or two, the module should sense the presence of a flame and only then send gas to the main burner.
I have been playing with it off and on since my last post. Still nothing!!! Figured its time to fork over the $150 to have someone come look at it and probably spend another few hundred to get it running.
So its been really cold down here in SoCal and my wife thought I forgot the chimney opening open so she went to go close it. When she did, the pilot light automatically turned on. Turns out she actually opened the chimney.
Figured someone could learn from my silly mistake. If you are going to work on your fireplace make sure the chimney is OPEN!
