This dryer has had a new gas valve, complete with new solenoids and a new electronic control installed. The unit will ignite and burn for about 30 seconds completely stripped. (Tub and front out and off) With tub back in and front tub support in, it still works for about 30 seconds. Once the front cover is on, The igniter comes on, it goes out just like it is going to work but the gas valves don't open if the front is on. This thing is driving me to drink more than usual. Hopefully someone has seen this craziness before. ( Prior to new valve and board, the unit would ignite once and then just keep cycling like it was going to ignite, igniter comes on, then goes out but never a gas release except the first time.)

Why would putting the front on affect the flame sensor? It opens each time the igniter comes on. It's true I have not replaced it. I've got $250 of my money in it now. This is the first appliance I have ever failed to fix.

Is the vent clear going outside? Did you check the thermostats?

Thats a strange one. It has the symptoms of a bad gas valve coil but since thats all new...I don't know. I wouldn't suspect the flame sensor to be a problem if the ignitor is cycling on and off. I also wouldn't suspect the thermostats or thermistor either if the ignitor is heating since it wouldn't be doing that if one of those parts were bad. I think I would try a new set of coils on the valve and see what happens. If that doesn't work check the control to be sure its not cutting power to the valve just after the ignitor is heating up.

I'm pretty sure the only way to replace the coils on an LG gas dryer is to replace the complete valve which comes with new coils which has already been done, so unless the new valve is bad there must be some other problem.
Sounds to me like there is a gas supply problem, do you have any other gas appliances in the house and if so, do they all seem to be working OK?
Gas supply line not twisted and pulled tight causing it to crimp off so able to light the first time then not enough pressure to keep it burning? I had an earthquake shut-off valve to the house tripped and with a whirlpool dryer it would light up and the flame would just poof out almost looking normal then in only 1 second or less disappear and then not light again until you let it set for a couple minutes and the pressure would build-up again for another try.

We have exactly same issue. We already replaced 2 gas valves thinking 1st was defective. Same symptoms. Ignighter light up and cuts off after 15 - 20 sec. But not lighting gas. We checked everything else and all other parts seems to be ok.
