Customer Questions and Answers for Dryer Moisture Sensor Bar by Lg

By: Lg
Part Number: OEM13335393
Manufacturer Part Number: 6500EL3001A

The Dryer Moisture Sensor Bar is an OEM part for LG dryers. It plays a critical role in detecting the moisture level of clothes during the drying cycle, enabling the dryer to adjust the drying time automatically. This ensures efficient operation, preventing over-drying, which can damage fabrics and increase energy consumption.

Symptoms of a bad Dryer Moisture Sensor Bar include:

  • Clothes remaining damp after a complete drying cycle
  • The dryer continually running without stopping
  • Inconsistent drying results, with some clothes over-dried and others still wet

Causes of a bad moisture sensor bar can stem from a buildup of lint and fabric softener residue, which insulates the sensor and impairs its ability to accurately detect moisture. Additionally, wear and tear or damage from loading and unloading can affect its functionality.

Regular cleaning and maintenance are recommended to ensure that your LG dryer operates efficiently and preserves the life of your clothes.

Jeremy for Model Number Kenmore Elite 79681582410

Reading online I found that I need to clean the moisture sensors to achieve proper drying. Here's the thing though, I owned a Siemens UltraSense dryer for 11 years prior to purchasing this dryer. Never once cleaned the sensor bar. Ever. There is something wrong with the programming of these dryers, period. Selecting "More Dry" shouldn't shorten the timer. But it does. Maybe the koreans prefer wet moldy clothes? My Siemens still works great, it was just getting overloaded with the quantity that the matching elite washer can put out. So I did clean the moisture bars, it made a difference for 2 weeks. Like hell am I going to tear apart the drier to clean these bars in solvent every two weeks, there must be a better more permanent solution? A smart appliance manufacturer would have factored for the dryer sheet film when calibrating... would they not? Maybe to the extent they would have ran 30 normal loads and then calibrated? I know alot of this rant belongs elsewhere, which once I actually find that elsewhere, it will be there too.

Answer

Jeremy, This is not a "new" problem, it dates back to the 70's and 80's, when fabric softener sheets became available on the open market. In your case, if the sensor bars are coated with the chemicals from the sheet, it does not sense the moisture in the clothing properly, and the data to the control board indicates the load is dry and it shortens the cycle and shuts down "early". Not everyone uses softener sheets or liquid softener. It's hard to "calibrate" for something you don't know or may or may not occur. Cleaning the sensor bars with alcohol or a non flammable solvent, is the easiest and quickest way to solve the issue, of course you can replace the bars should you choose 6500EL3001A / 6500EL3001A . A couple of things to check or do to help remedy the issue. Check and make sure the dryer is level in both directions(maybe 1/8 to 1/4 inch higher in the front wont hurt), make sure the dryer isn't being overloaded(never more than 1/2 full). and remove and discard any and all fabric softener sheets when the dryer is unloaded.
