- DLEX4000B
Can I install this dryer in a closet with a door?
Yes, but the closet must have both upper and lower vent openings. The manual requires an upper opening of at least 48 sq. in. (310 cm²) no lower than 6 feet above the floor, and a lower opening of at least 24 sq. in. (155 cm²) no more than 1 foot above the flo
- DLEX4000B
Can I overload the dryer?
No. The manual says not to overload the dryer. Overloading reduces drying performance and energy efficiency, and clothes need room to tumble and dry properly.
- DLEX4000B
Can I run the dryer without the lint filter?
No. The manual says never operate the appliance without the lint filter in place.
- DLEX4000B
Can I use plastic venting for this dryer?
No. Do not install the dryer with flexible plastic venting materials. Use only rigid, semi-rigid, or flexible metal ducting as specified in the manual.
- DLEX4000B
Can the dryer vent into an attic or crawl space?
No. Gas dryers must exhaust outdoors, and the manual says not to vent into enclosed or unventilated spaces such as an attic, wall, ceiling, crawl space, chimney, gas vent, or concealed space.
- DLEX4000B
How do I know if the exhaust system is okay after the installation test?
If the Flow SenseTM LED does not turn on when the cycle ends, the exhaust system is adequate.
- DLEX4000B
How often should I clean the lint filter?
Clean the lint from the filter after every cycle.
- DLEX4000B
What do d8O, dGO, and dGs mean?
These codes mean the exhaust system is too long, has too many turns or restrictions, or the house exhaust system is blocked.
- DLEX4000B
What does it mean if the Flow SenseTM LED turns on during the test?
It means the exhaust system is severely restricted and should be checked immediately, because performance will be poor.
- DLEX4000B
What does Sensor Dry do?
Sensor Dry cycles use LG’s dual sensor system to compare moisture in the clothes and in the air, then adjust drying time as needed. The dryer automatically sets the dryness level and temperature for the selected cycle.
- DLEX4000B
What does the Clean Filter indicator mean?
It lights at the beginning of the cycle to remind you to check the lint filter, and it turns off when you press Start/Pause.
- DLEX4000B
What happens if the lint filter is loose or missing?
Running the dryer with a loose or missing lint filter will damage the dryer and the articles in it.
- DLEX4000B
What parts are shown on the front of the dryer?

- DLEX4000B
What should I do if clothes come out wrinkled?
Try a shorter drying time or a lower dry level setting, and remove items while they still have a slight amount of moisture. If clothes are left in the dryer after the cycle ends, use Wrinkle Care to tumble them briefly every few minutes for up to 3 hours.
- DLEX4000B
What should I do if the lint filter is clogged with fabric softener?
Wash the lint filter in warm, soapy water and allow it to dry thoroughly before reinstalling it.
- DLEX4000B
Why does my dryer start by itself every few minutes?
This is how the Wrinkle Care feature works. The dryer runs briefly every few minutes for up to 3 hours after the cycle finishes to help prevent wrinkles if you do not unload the dryer right away.
- DLEX4000B
Why does my dryer take a different amount of time for similar loads?
Drying time can vary based on load size, fabric type, how wet the clothes are, and the condition of the lint filter. An unbalanced washer load can also leave clothes wetter and increase drying time.
- DLEX4000B
Why does my dryer take so long to dry clothes?
Poor airflow can increase drying time. A lint filter that is full of lint or clogged with fabric softener sheet residue can reduce airflow and make drying take much longer. The manual also refers you to the troubleshooting charts for more tips.
- DLEX4000B
Why should I clean the lint filter before every load?
A clogged lint filter increases drying time. The filter should be cleaned and reinstalled firmly before starting the dryer.
