Here's the problem: There is a dial on the dryer that should allow me to adjust for 'more dry' and 'less dry'. Up until recently, I could set the dial, and end up with clothes that were either 'more dry' or 'less dry', depending on what I wanted. If I set the dial, I got the appropriate dryness. THEN, all of the sudden, it didn't matter how I set the dial, the dryer would just run on and on, until my clothes were practically baked. No matter how you slice it, the dryer was functioning differently. I DON'T think the problem is with the timer. The model number is PVXR333ET5WW

possible blockage in vent if ok bad fan motor or heating element overheating

is there a switch for high and low heat,.......might be set on low......

cheers

New electronic dryers are smart appliances. Your device is probably equipped with a conductimetric sensor that has a function to measure humidity of laundry and in accordance with that increasing or decreasing the drying time. So, it is normaly that appliance stop if you did not put the wet laundry. In the user manual is described as adjusting the level of conductivity (if featured) depending of the water in your area. The conductivity of the water used to wash the fabrics varies from zone to zone.
The conductimetric sensor is calibrated to a standard value: any major variations in the level of conductivity may affect the final drying result (i.e. the washing may be too dry or too humid).

From user manual:

Adjusting the level of conductivity
Water contains, a variable quantity of limestone and mineral salts of which quantities vary according to geographical locations thus varying its conductivity values.
Relevant variations of the conductivity of the water compared to those prefixed by the factory could slightly influence the residual humidity of the laundry at the end of the cycle.
Your dryer allows you to regulate the sensitivity of the drying sensor based on conductivity values of the water by using the following procedure.

Procedure:
Turn the programme selector dial to switch on the appliance
In selection mode press simultaneously the buttons 3 and 6 until «C0» appears on the digits.

Adjusting the level of conductivity:
Press the button 5 sequentially: the level of conductivity is indicated by the lighting of the horizontal hyphens.


Normally, the appliance is factory-set to the highest level; however, certain models may be configured differently.
Memorizing the new setting:
Simultaneously press down the buttons 3 and 6 until the previous drying cycle time appears again on the display and the buzzer sounds.

if there is no heat, there is no drying and the dryer will not shut off until the clothes are dry. Sounds like you have an electrical problem, bad heater or thermostat. we do not have sufficient information to help you, you will need specific tool to determine the problem and for performing the repairs.

Controls

• The control unit on the tumble dryer will vary among different makes and models. The main purpose of the controls is to allow the user to select the drying cycle. You can choose the time and temperature setting on most units, while others allow custom settings such as moisture sensors and end-of-cycle alert signals. The controls may include a dial or a touch panel and LED screen display. Some tumble dryers allow you to independently select the appropriate time for the load you are drying and separate programs for temperature.
  

Motor

• The motor inside the tumble dryer spins the basket to allow the clothes to tumble while being dried. The tumbling action allows the air to pass through the clothing to dry them faster. Heating laundry that is stagnant will likely dry the clothing on the outside while leaving damp clothing inside the pile. The constant motion, along with the heat and steam created by heating the clothing, reduces wrinkles. The motor also powers the fan that delivers the heated air to the basket of laundry. The heater can be an electrical element or gas powered.

Note that the time can be adujsted in all cycles EXCEPT the Normal cycle. (Page 8 of the manual)

Select Options (if desired)

Adjust Time

Time can be added or subtracted from the

automatically set times in the Delicates, Wrinkle

Release, Damp Dry or Air Fluff cycles.

To subtract time from the cycle, press the Less Time

pad until the desired time is displayed. To add time to

the cycle, press the More Time pad until the desired
time is displayed.

You may need to adjust the air flow on your dryer vent.
When an LG dryer is functioning normally---the time required to dry laundry is determined by the *Sensor* located on the drum side of the lint filter housing and by the main control board.
When laundry is near dry--any Time Remaining on the control panel that is *not* needed will be eliminated---except for the last 6 minutes.
The final 6 minutes of any LG automatic cycle is for cooling down the laundry before the dryer ends the cycle.
If a dryer *counts down* to the last 6 minutes but the laundry is still not dry--the computer will allow the dryer to run until the laundry has dried or defaults (not drying within the additional time allowed).
Dryer vents that are longer than 8 feet with more than (2) 90 degree turns--can affect drying performance.
Setting the DRY LEVEL selector to *Very Dry* will solve most dryability issues. In homes with abnormally long vents--even the longer run time in the *Very Dry* setting is usually not sufficient to dry laundry loads.
Reducing the length of the vent or starting a second cycle becomes necessary to fully dry the clothing.
If a second cycle was started---only the amount of time that is needed to dry laundry will be used before dropping to 6 minutes and then the cycle will end with dry laundry.
*****************************************

LG gas dryers are more sensitive to venting length and air flow resistance. The gas burner can cause a rapid increase in temperature compared to an electric burner.
Rapid temperature rise in a gas dryer leads to premature burner shutdown (longer time required to dry laundry).
The gradual temperature increase of an electric element is more "forgiving" in homes where the dryer venting is less than ideal.
*******************************************

Problem:
The dryer has an auto dry feature which never fully dries the clothes so we wind up manually setting the dry time to an hour
Solution:
LG gas dryers are VERY temperamental in long vent set-ups. If fabric softener sheets are used in the dryer--clean the two stainless steel strips of metal on the lint filter housing with a SCOTCHBRITE PAD--scrub back & forth several times to remove the waxy residue from the fabric softener sheets. Most,if not all manufacturers do *not* recommend using sheets in dryers that have a moisture sensor (electrodes).
However--using a SCOTCHBRITE pad keeps the wax off those sensors which can be seen if looking *into* the dryer drum and at the lint filter housing.
If only *liquid* fabric softener is used in the washer--clean the dryer sensors once a month. Liquid softener also contains wax which can slowly accumulate on the dryer sensors from the laundry washed in the washer.

HI. This will occur when the there are issues that concern the integrity of the timer motor. This mechanism is responsible for the rotation of the timer module.It is damaged at this time, and it must be replaced asap.

A damaged timer motor will affect the nature of the drying cycle. It is the main initiator of all functions during the selected cycle.

You can make adjustments to your Automatic Cycles by adjusting the Factory Dryness Level:
Changing the Automatic Cycle settings to increase or decrease drying time:
If all your loads on all Automatic Cycles are consistently less dry or more dry than you would like, you may change the default settings to increase or decrease the default dryness
level.

Your automatic drying settings can be adjusted to adapt to different installations, environmental conditions, or personal preference. This change is retained and will affect all of your
Automatic Cycles, not just the current cycle/load. There are 5 drying settings, which are displayed using the time display:
0 Much wetter clothes, 30% less drying time.
1 Slightly wetter clothes, 15% less drying time.
2 Factory preset dryness level.
3 Slightly drier clothes, 15% more drying time.
4 Much drier clothes, 30% more drying time.
TO CHANGE THE DRYING SETTINGS: NOTE: The settings cannot be changed while the dryer is running or paused. The dryer must be in standby mode (power is off) to adjust the default settings.

1. Before starting a cycle, touch and hold DRYNESS for 6 seconds.
2. Touch DRYNESS to select the dryness level shown in the time display: 0, 1, 2, 3, or 4.
3. Touch START/PAUSE to save the new dryness level setting.

Recently, I have seen this. I don't like to rig things BUT if the know will not attach itself you will have to either glue it or keep pliers next to your dryer. Sorry, but good luck. The other option is to replace the timer with a new knob.
