Cleaned duct. Replaced duct actually. Cleaned inside back vent of dryer. Cleaned lint. Got one of those duct cleaners you feed up the duct on an electric drill.

Is my last option checking the vent on my roof? Yes my stupid arse house vents up.

I think you found your problem.

Pull the drum and check that the exhaust fan belt hasn't came off the gear. That happened with mine a few years ago. I just had to get the belt back on the motor gear and fan gear.

I'll do that tonight. Only thing I haven't done is open it up to look inside

Thinking back I didn't even have to pull the drum. Just lift the top cover, swing the front across, and there should be enough open space under the drum to see the blower directly under it and the motor to the side. There should be a fan belt connecting the two.

If this is the issue, honestly the hardest part will be finding the belt where it flew to when it popped off at mach speed. Getting it back on wasn't easy either, but I was able to brute force it without breaking it or the gears it connects.

I popped it open tonight. The front inside cover actually had a bit of build up. Build up in the front part of the vent as well. Under the drum didn't look bad.

Will test later this week

I sounds to me what could be happening as the warm/hot humid air, which has a high dew point temperature, is vented from the dryer up the vent/flue pipe, as it comes into contact with the cold metal vent pipe in the attic, near the roof line, the water vapor in dryer exhaust air is condensing into liquid water and running back down the vent and pooling up at the bottom of the dryer.

It’s physics/psychrometrics - when the dew point temperature of air containing moisture contacts a colder surface it condenses to liquid water. I doubt if it’s a dryer/mechanical problem per se.

I suspect It’s likely only a problem that is occurring in winter and not when the temperature in attic is warm/hot.

Short of being able to vent the air horizontally over a short distance out the house, you could try insulating the portion of exhaust vent pipe that is in the attic up to the roof to see if that corrects the issue, and/or you might need a booster fan to get the dryer vent exhaust air out of the house more quickly. Here is an article with suggestions LINK

Anyway, just additional thoughts for you to investigate/consider.

Well that's something I never thought of. The dripping started this winter. It mainly pools under the dryer itself rather than dripping from the vent from wall. But I will look. That's an interesting thought.

That’s unfortunately common when the laundry room is not on an outside wall.

I had to eventually put in a booster due to constantly having issues caused by poor airflow.

Why wouldn't the builder install the vent line before pouring the slab and have it run it to an outside wall, even if it's not installed on an outside wall? Or, if a crawl space, you can easily run it to an outside wall.

My last two homes were slab built and the vent line was run through the slab to an outside wall.

I've had this happen, it's the vent in the roof most likely. I put my hand in my vent and found a ton of junk in there. I cleaned it out and my clothes were actually dry after the dryer ran...

Yes. It's beyond stupid.

Even after cleaning vents the dryer is still leaking condensation. At this point, the only thing I've not thoroughly cleaned is the vent duct to the outside and checking the roof outside vent.

That's next.
