LG DLEX5780WE dryer: shutting off before the clothes are dry.

Have a DLEX5780WE lg dryer shutting off before the clothes are dry. After looking online and testing the moisture sensor I found out that they didn't have very good conductivity continuity. I replaced this but the same thing is happening. I checked continuity on the new sensors and they are working perfectly. I plugged and unplugged the harness a couple of times to make sure I had pressed it in completely and didn't miss anything. After about 5 to 10 minutes the dryer stops as if the clothes were dry. Timed dry seems to be working give. What am I missing?

Is the timed drying working ok ?

The really isn't any way to check the dampness sensor.
It's two contacts that wet/damp clothes short out and extend the cycle.

Yes timed dry is working fine. Like I said, I replaced the sensors. Double checked sensor continuity and connection is the sensor to the harness and that looks fine. BWhat else should I look into/check?

Btw, if a "deep lint cleaning" (if that's a thing) it's recommended where I have take the thing apart, if you could provide a link to how to do that/ take it apart I'd appreciate it.

I'm not finding any service info online. You can purchase a service manual.
The auto dry system is fairly basic. There are the two sensor bars and the control board.
In theory if it's not one at fault.... it's the other.

I hate to just jump to conclusions that the board is bad.
Many have posted that after they cleaned their dryer it worked fine.
That doesn't make complete sense since the sensor is monitoring moisture in the clothes.

As far as cleaning..... this video looks similar to your dryer as far as cleaning.
