Why does it increase time to 3H when there are 8 minutes of drying time left?
From what you're describing, there could be a problem with the moisture sensor circuit. On the front of the lint screen holder(you have to stick your head in the dryer and look back, you will see 2 metal strips. These are the sensor bars. When wet clothes brush against them, it lets the computer know that the clothes still have moisture in them and about how much. As the moisture decreases, the electrical signal changes and the computer counts down. The time is JUST AN APPROXIMATION. However, if the sensor bars become shorted, or if there is a problem with the wiring of the sensor circuit, or if the main control board is defective, these will produce the problems you're having. One important thing to note: Samsung dryers, when using the sensor-dry settings, like to have large loads in order to work properly. And, try to have like items with like items(jeans with jeans, shirts with shirts, towels with towels, etc) If you have *small, mixed loads*, use the timed-dry settings for best results.
Also, check inside the lint screen holder with a flashlight(with the lint screen removed) for a large build-up of lint. If there is a significant amount of lint, you could have a partial blockage in the dryer vent tube or wall causing restricted airflow--this will cause longer drying times because the hot air, containing moisture, can't exit the dryer properly. THE RULE OF THUMB ON ALL DRYER VENT TUBES IS: **KEEP AS SHORT AS POSSIBLE, NO SHARP BENDS OR KINKS, STRETCHED OUT(if using the cheaper foil or plastic accordion type)**** Remember, gentle bend coming out the dryer, gentle bend going into the wall. The airflow coming out of the vent(outside the house) had better be close to what's coming out of the rear of the dryer, otherwise there is some type of restriction in the air path that must be removed.
