Hello, I have an LG gas dryer model DLG0452W. Currently, it tumbles, the igniter glows but the gas valve never opens. The igniter will kick on for about 5 seconds, then kick off for about a minute or so then start glowing again for another 5 seconds. I have installed a new igniter and a new gas valve (which has the coils included as one unit). Still it continues this cycle of glowing for 5 seconds and then turning off. I have also checked all thermostats and limits and they all have continuity. I really have no idea what I can test/replace next. Any ideas/advice is welcome. Thank you in advance!
Check gas orifice for blockage. (Make sure gas is turned on obviously.)

It appears that everything in the heating circuit is replaced except the igniter which glows and therefore also working fine. But with all of these, there's no voltage to the gas valves. Perform a gas valve wire harness and connector continuity check and also measure voltage right the PCB terminals going to the gas valves. Either voltage is not getting to the gas valves due to a loose/broken wire harness or the PCB is not sending voltage to the valves.

Well for starters VERIFY tons of air flow OUTSIDE of the building. To test, pull hose from back of machine, turn on and form opinion of air volume. Then hook back up, turn on machine, go outside and see if you have similar air flow. Commonly there is a restriction. This will cause thermal limiters to stop the heating.
Did you reset the circuit breaker located on the burner at the 7o'clock position.
