I have the same problem, only my "cooling" light stays on - could the dryer possibly be trying to heat and cool at the same time? It almost appears to be a computer issue... (this problem came on suddenly after we moved the dryer into a new house)

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.

    To recap: The sensors have wet clothes rubbin against em. The wetness of them clothes creats a resistance that is moniotred by the on board intel. When the magic number is met, the dryer shuts down thinking all is good because the real wetness ain't no longer being sensed through all that gunk and gookus built up on them sensors.

    Captain we have a problem. What is it spock? Don't tell me the laundry ain't finished. Worst captain, an unknown substance has coated sensors. Spock what do you make of it? Captain as best as I can tell the residue from all of them trips through the neutral zone has left a funk. What will we do Spock? If only we had some C3H8O...

SOURCE: My LG TROMM DLE7177 on heating cycle finish much quicker

First off, unless you are using the manual dry (timed dry) option, the times listed are strickly an estimate. At the begining of a cycle, the dryer has no idea how big a load you have, how wet it is, and how good your vent is. In your situation, I would clean off the two silver colored moisture sensor bars, located just inside the drum, by the right side of the lint filter area. They are curved, about 5 inches long, and about an inch apart. If you use fabric softener sheets, they can aquire a waxy build up, which inhibits them from detecting that the clothes are still too wet.

SOURCE: there is a lack of heat. It gets a little warm

Please ensure that the venting from the dryer to the outside of the house is clean and free of lint.
Ensure the venting behind the dryer is not kinked.

Long time to dry issues are usually caused by restricted venting to the outside.

Since you have heat this may solve the problem.

ALWAYS UNPLUG YOUR DRYER BEFORE ATTEMPTING TO DO ANY WORK ON IT.
Check to make sure you are getting full 220 Volt power to the dryer, if you are then:
Check your Wiring
Often the main wiring connection from the house, at the dryer, burns and the connection breaks. In this has happened to your dryer, you need to replace the power cord and the terminal block inside the dryer to which the wire is attached.
Check the Door Switch
If the door switch or the door-switch actuator is defective, the dryer won't work and you need to replace the failed component. The switch is inside the dryer main housing near the door frame. Sometimes you need to raise or open the top or front of the dryer to reach the switch. Check for continuity you should have none with door open, and should have a reading when closed. If not replace the door switch.
Check to make sure you heating problem is not a lint build up in the discharge hose or the dryer,as this condition can cause heater/thermistor problems such as overheating of the heating coil leading to failure of the coil and burnout of the thermostat/thermistor due to overheat.
Sounds like your problem may be with the heating coil. Remove the back/or front just under the door of the machine and try to locate the air duct going from the blower to the drum. Normally inside/outside the air duct you will find the heating coil and the thermostats/thermistors. Once you have located the heating coil, remove the two wires from it and check the coil with an ohm meter across the two terminals of the coil.
You should read continuity across the terminals, if not you will need to replace the coil as it is faulty.
If the heating coil is ok, then:
You can check the thermostat/thermistor one at a time by removing the two wires and taping them together with electrical tape or with an ohm meter to test the thermostat/thermistor. (Should have/show continuity)
If the coil heats up then replace the thermostat/thermistor.
(Thermal fuse.If it overheats the dryer will not operate. It's located on the blower housing. It cannot be reset. A vent clogged with lint can cause it to overheat. You can test it with an Ohm meter or continuity checker, if no continuity, replace it)
DO NOT LEAVE THE WIRES TAPED TOGETHER AFTER THE TEST.
This could cause a FIRE, as you have removed the safety of overheat from the machine.
Right after replacing a dryer element, always run the dryer on 'air fluff' / 'no heat', and go outside to verify there's plenty of air coming out your vent system.
If the vent's clogged, that new element can burn out very quickly.

The heat is there but it doesnt dry the clothes


You have one of 2 problems. Your clothes are getting put into the machine too wet because the washer isn't spinning them out all the way. Or you have a clogged vent causing the unit to take too long to dry properly because it can't remove the moisture properly. Check your vent outside to see how hard the dryer is blowing the air.

Moisture control


Dryers have 2 basic types: AUTODRY and Electronic. The electronic moisture control relies on 2 bars inside the dryer. As wet clothes rub these bars the wetness discharges the capacitor on the moisture control board. As long as the cap don't get a full charge the timer motor will not advance forward to the end of cycle. What goes wrong on these? Wax buildup on moisture bars form a barrier that keeps wetness off them bars. The control thinks them clothes is dry and shuts her down. On autodry the timer motor advances very slowly, The motor does not work while the heating element is on. Only when the heating element is off does the timer motor advance. As them clothes gets dryer the temp inside the dryer stays warmer and therefore the dryer thermostat keeps the heater off long and the timer motor advances. Like being on a highway with traffic jam you go a little bit then stop then go a little bit more then stop. Finally you get there. So what goes wrong? The control thermostat is not functioning properly causing the heater limit to do all the work . Instead the heater limit has to do the work and it ain't a real happy camper. Makes them clothes get too hot. They come out wrinkled.

I have a Kenmore 500 series dryer, model number 110.79522800 that will note completely dry clothes. It seems like it doesn't run long enough, heat high enough or a combination of both. What can I do to...


Your Sensor that senses the clothes are wet or dry is shorted out. The dryer works likes this so the dryer heaters dont stay on while the clothes are dry. When the sensor senses the clothes are damp or wet, the heater stays on, when they start drying the sensor senses it and starts to turn down the heaters

Clothes aren't dry


Heating and not drying can be caused by 3 different things. I will address all three most common first

- Restricted air flow, usually a blocked vent. If the moisture from the laundry cannot get outside and fresh air in the dryer you will take extra long to dry. Be sure there is ventilation into the laundry room and more important make sure the vent is not kinked behind the dryer and that it is clean and allowing good air flow. You can go outside to where the vent terminates and feel the flow while it is running to check.

- Sensor has build up on it. Look in the dryer drum, inside on the back wall, inside on the front wall, somewhere depending on your model you will two strips of metal about the size of a pencil. Clean those with a little alcohol. Those are what sense the wetness of the clothes and control the cycle. If they get a build up residue on them they do not sense properly.

- The load is mixed, meaning you have some articles that absorb moisture like towels and some light garments that dry fast, the fast drying articles can fool the dryer into thinking the entire load is dry when the heavy articles are not.

My daughter in put a load of wet clothes (not completely finished spin cycle). Now dryer doesn't heat the clothes but seems to have all other functions.


Try running the dryer empty to see if the elements are heating. With the weight of wet clothes it is possible to trip the overloads.

NO HEAT WHEN CLOTHES ARE ADDED


Check to see if vent hose is not restricted. If it goes up inside wall, it could have lint clogging it. Most dryers regulate heat with air flow. Wet clothes can restrict flow even more if vent is clogged or pinched. Air flow is crucial to heat cycle. If the vent is resrticted, heat will rise quickly, but not cool down fast enough to allow heat thermostat to cool down and turn on heating element again. It may seem hot inside dryer but if no air flow it will increase dry time or not dry them at all before timer shuts off. If vent goes up inside wall, buy a small chimney brush and try cleaning out vent from attic if you can.

Broken washer/dryer


This sounds like a motor control board is faulty. Please load a couple of towels in the machine run it. Watch the machine as it goes through its' cycles.

1. Do the towels tumble when the machine is washing ?
2. When it begins to spin, does it spin one way at a fast pace or does it spin one way and then the other ?

Answering these two questions will help in troubleshooting your problem.
