The air flow through the system is good and not clogged. Took the dryer apart and ran continuity on the Gas Valve Coils. I replaced them because they were open. After replacing them, the dryer appeared to work (makes clicks we had not heard before replacing) but the clothes still do not dry. The exhaust is cool and the heater box only heats for ~8 seconds before shutting off. Running the dryer with the door open, I can feel a good amount of heat--it just doesn't last. The heat will cycle on (~8 seconds) and off (~1 minute) for the duration of the timer.

I tested the two thermistors on the heater box, which are in series, and they have continuity. Unplugging them causes the dryer to turn off, so I assume they are okay (but not necessarily working properly). I checked the Thermal Fuse and it is a short (good). Close to the Thermal Fuse is, I think, the thermostat. Not sure how to test this since there are about 6 wires plugged into it, however, the air reaching it is cool so I don't know how it could be acting that fast.

It is frustrating not being able to find schematics because those would help me troubleshoot the system with better efficiency. So, here I am asking for suggestions. Thanks in advance!
