LG dryer DLE5977B clothes not drying completely
« on: May 02, 2012, 12:47:33 PM »
Hello Forum, I'm working on repairing a LG dryer DLE5977B that is not drying the clothes completely. Only check I have done so far was to see if the exhaust vent leading from back of the dryer to outside vent was clean. (checked-clean). Any repair advice would be appreciated!!!. I just finished the problem I had with the washing machine using this forum. Great forum!!!   Thankyou !!!  Tool-n-Die.

***************

Assuming the entire vent system is clean/clear...

If Fabric Softener Sheets are used in the dryer---laundry will be approximately 90% dry (on a regular basis).

This is caused by *wax* build-up on the MOISTURE SENSORS from the FS Sheet.

The waxy residue on the MOISTURE SENSORS will cause the MAIN BOARD to "think" that the laundry has become dry at/near the end of the cycle.

There are 2 options:

1) Discontinue using FS Sheets

or

2) Clean/scrub the MOISTURE SENSORS with a *ScotchBrite Pad* after each load in the dryer (when a FS Sheet is used)

The MOISTURE SENSORS are located on the *drum side* of the Lint Filter Housing (2 silver metal strips).
These can easily be found on the Lint Filter Housing by placing your head into the drum and looking downward at the Filter Housing.

Additionally...

If a *small* load has been placed in the dryer---the damp/wet laundry may not be making contact with the Moisture Sensors often enough (causing rapid termination of the cycle).
Raising the rear/back leveling legs of the dryer---about an inch higher than the front of the dryer---will cause small loads of laundry to tumble at the front of the drum (continually making contact with the Sensors).

Good job on the washer :)

We've noticed that on the default NORMAL dry level (gov. Energy Star regulations)
the clothes are slightly damp.
We now always adjust it to the next level up, MORE DRY

******************

Yes---this is a *big* help if the dryer exhaust vent is much longer than 8 feet total length

or...

The laundry load is large (full).
Some fabric types---such as denims---will require more "run" time than a load of t-shirts,for example.

By changing the DRY LEVEL selector to 'More Dry" or "Very Dry"---this simply adds more *time* to the Display (shown in minutes).

If too much time is selected in any SENSOR DRY cycle---the MAIN BOARD will eliminate any excessive cycle time remaining---as long as the MOISTURE SENSORS are kept clean/free of waxy residue.
