LG Dryer Error Code bE

The bE code on an LG dryer means the appliance detected a dry time that exceeded the expected maximum for the selected cycle. This is caused either by an open or non-functioning moisture sensor bar inside the drum, or by the user pressing the Adjust Time Up button too many times to extend the cycle. The control board flags this condition and stops the cycle to prevent the dryer from running indefinitely.

You should not continue running the dryer until the bE error is resolved. An open sensor bar means the dryer cannot accurately determine when clothes are dry, which can result in extended run times and unnecessary heat exposure to the drum and clothing. Resolving the root cause before resuming use is the recommended approach.

If the fix is simply cleaning the sensor bar, the cost is minimal, just a few minutes and a small amount of rubbing alcohol. Replacing a moisture sensor bar typically costs in the range of $15 to $50 for the part, with additional labor costs if a technician is hired. A control board replacement, which is the least likely repair needed, can range from $100 to $250 or more for parts alone depending on the model.

In many cases, yes. Start by checking whether the Adjust Time Up function was used excessively during the last cycle, and if so, simply restart without over-extending the time. If that is not the cause, inspect the sensor bar inside the drum for residue or coating from dryer sheets and clean it with rubbing alcohol. If the bar is physically damaged or the wiring has an open circuit, replacing the sensor bar or harness is a repair many experienced DIYers can complete.

A power reset, such as unplugging the dryer for a few minutes and restarting, may temporarily clear the bE code, but the error will return if the underlying cause is not corrected. If the sensor bar has an open circuit or damaged wiring, the fault will reappear as soon as a cycle runs long enough to trigger the control board's limit again. A reset is useful for ruling out a one-time glitch from over-adjustment of cycle time, but it is not a fix for a hardware fault.
