Why does the lint go inside of the dryer with the clothes and clothes will not dry?

Do you have an outside vent that has a mesh or screen to keep wildlife from entering it? It could be blocked by lint accumulation. Sound like airflow out might be restricted. It is getting warm or hot (depending on setting), isn't it.

"Did everything I had to do". Meaning what? If you pushed the dryer too far back, it kinked the hose and blocked airflow.

An even more likely explanation if it was sudden.

Most likely it is dirty and lint deposits have built up, as it always does, in all the air ducts. You will have to take it all apart and clean the drier out thoroughly or it is all for nothing. Every air duct will have to be removed and scraped and washed out to remove baked on lint deposits which bakes on like a concrete lining. This will burn so the manufacturer has installed the safeties to keep from having a house fire. Driers were the number one cause of fires at one time, hence now we have safety fuses.

When you finish cleaning the drier it is best to also replace the belt, too, because you do not want to have to disassemble it all over again and if the belt is over two years old you should replace it, and you will have to grease all bearings with white lithium hi-temp grease. Here are some manuals:

Note that on most of the videos it does not show them washing out the parts, but this is important because it's the only way to really get the parts clean, just don't get motor wet or the capacitor if it has one. Vacuum out the motor to remove all dust. I would move the drier out to your garage to have plenty of space to work. You also want to check your vent and clean it, also. The vent should have a short run and be straight as possible. The job is really easier than it sounds. There is no shortcut that will work; it has to be cleaned well. Before you re-assemble it make sure to use white lithium grease (high-temp grease) and grease all bearings.
