Understanding the Problem
The moisture sensor (sensor strip) in the LG DLEX760OKE tells the dryer when clothes are dry so the automatic cycles can end at the right time. When the sensor fails or reads incorrectly you may get cycles that run too long (overdrying), cycles that end too soon leaving clothes damp, or the dryer may rely solely on the timed cycle and ignore moisture-sensing modes. Most sensor problems are caused by corrosion, residue buildup on the sensor bars, a damaged harness/connector, or an actual failed sensor assembly. In some cases the control board or wiring that reads the sensor can be at fault, but the sensor strip and its harness are the most common service items to check first.
Common Symptoms
Dryer overdries or underdries clothes, automatic cycles ignore dryness setting, run-on or very short cycles, error codes related to sensor (or intermittent correct/incorrect drying performance).
Common Causes
- Dirty or corroded moisture sensor bars (residue from fabric softeners/bleach)
- Damaged moisture sensor strip or harness/connector (open circuit or intermittent)
- Faulty main control board or sensor input circuitry

Helpful Repair Tip
First clean the metal sensor bars with a cloth and rubbing alcohol — residue often causes false readings. If cleaning doesn’t fix it, use a multimeter to check continuity of the sensor harness and test resistance changes as you simulate wet and dry conditions, or temporarily short the sensor input (with power off and according to wiring diagram) to see if the dryer exits the moisture-sensing mode.
Frequently Asked Questions
How do I tell if the moisture sensor is just dirty or actually broken?
Start by unplugging the dryer and cleaning the metal sensor bars inside the drum with a soft cloth and rubbing alcohol to remove fabric-softener and lint residue. If the problem persists, use a multimeter to check the sensor harness for continuity and observe resistance changes when the bars are wet versus dry. If cleaning has no effect and the harness and connector show correct continuity but the dryer still misreads moisture, the sensor assembly is likely faulty.
Can I bypass the moisture sensor and will the dryer still work?
You can temporarily run the dryer in a timed cycle that ignores the moisture sensor (use ’Timed Dry’ rather than ‘Auto Dry’), but bypassing the sensor electrically is not recommended as a permanent fix. Running without a functioning sensor risks overdrying, wasting energy, and damaging fabrics. Best practice is to clean or replace the sensor strip or repair the wiring; replace the control board only if diagnostics point to it.
