situation:
Gas dryer igniter lights up, flame is on, for a good 2-3 minutes, flame goes off, and suddenly about 10-20 seconds later I smell natural gas... i open up the dryer and strong natural gas inside tumbler.
I have already replaced the following:
Flame Sensor
Igniter coils
entire valve assembly kit
Not sure what to look at, possibly the control unit is keeping one of the valves open when the heat cycle is off? I guess i would need to test to see if valve 1 and valve two are working but I don't think thats the problem since I just had the whole dang part replaced... any idea how I can check to see if it's the controller?
Or for that matter any other areas i could check?

Hi
If you look at the posts on this site that involve heating problems with gas dryers you will see that they tend to get no response. I think the reason for this is that those of us who reply are electric folks, and I for one am not comfortable giving advice on gas burner issues. I suspect this is true of others as well.
If you have a gas burner issue on a clothes dryer I strongly recommend you get a service call from a qualified gas professional. Saving money on repairs is not worth the risk of the consequences of improperly operating gas appliances.
Good luck, and sorry I cannot be of help.

I don't have much choice but to ask (had 6 service men come) they keep replacing parts, and haven't been much help.. instead I mapped out the heat, tumble cycles and noticed that the gas valves open (with no fire up) for an exact duration of time during the heating/tumbling cycles..... I already had the entire gas assembly replaced, flame sensor and ignitor replaced... I think it's a controller issue but not a single repair tech will listen to me... does this seem like a controller issue? image attached dillusiv attached the following image(s):

Yes, I think it is a jproblem in your controller system, and it could bde either the control electornics or the wiring, but the thing that really concerns me is your dryer is not supposed to do this. These dryers have a built in "flame detect" systems that are supposed to shut down the gas jets and not allow gas into the environment if no ignition is present.
Rather than try to repair the machine I suggest you do the following.
1. Contact LG and explain to them that you have a major safety/hazardous issue and insist that they provide a remedy
and
2. If you are unable to get a satisfactory solution from LG I think you should replace the machine. I know this is an expensive option, but again, leaking natural gas is just too important an issue to play with.
Good luck, and please update us on your resolution.

I have had the exact same problem with my LG gas dryer. I was fortunate enough to be near a LG authorized service company. The technician rather quickly diagnosed this problem and changed the main control board. Problem fixed. The dryer did this right from the start, but it took me too long to make the call. The labor and parts was still done under warranty. I would say that this should have been a recall by LG but I have been unable to get them to fess up.

So searching for the main control board for this dryer the closest thing I find is called a circuit board. Is the the right part and where is it located in the dryer and if it is easy to replace?

Contact LG about this they may have a recall and tell them all the parts you've replaced. LG's are poorly made with cheap parts with numerous problems washers, dryers, fridges........call them and tell them how pleased you are with your unit (sarcasm)...I find it funny that there's been over 6000 views at this problem that people are trying to get help with which confirms my statement about a possible recall or major issue. Here's there website with contact info. LG Support USA: Customer Service and Technical Support | LG USA

Here's there website with contact info. LG Support USA: Customer Service and Technical Support | LG USA This is horrible. My wife noticed the gas smell within the past several months or so and we had the gas company come out to check. The tech determined something is wrong with the dryer but it's the same exact symptoms as what the original poster has described. Burner stays lit for what sounds like 20-30 seconds though then shuts off. Opening the door shortly after there's a gas smell. Seems quite dangerous. It seems like the kind of issue many people would ignore too, since the dryer works fine and dries clothes right? Most of the time, people only contact the manufacturer when something breaks and clothes don't dry. But when it comes to safety issues, it may not be as obvious. LG seems to take the stance that if it's not obvious, it's not an issue... this is neglect! I filed a report with the CPSC: 20150915-67BCA- 2147428373 Hopefully it gets published. We'll see...

Had an authorized LG tech come out to check it out. I told him that it seems like the control board is the issue and even the last repairman who came out (and decided not to pursue fixing it) told me he thinks it's the control board as well. But I think he was actually reading this thread before telling me LOL!!
Anyway, to 'eliminate' the possibility of the gas valve being the problem, the tech swapped it out with a known-good one. Problem still persisted. So he ended up deferring to it being the control board and placed the order upon me putting down a $100 deposit. Apparently, the entire thing will cost me around $350. Thanks LG, for making me fix what should be considered a major safety recall on my own dime!
