LG Dryer Error Code dt

The dt code on an LG dryer means the dryer has detected an invalid dry time that exceeds the maximum allowable limit. This can happen because the moisture sensor bar inside the drum has an open or non-functioning circuit, preventing normal cycle completion. It can also be triggered by pressing the Adjust Time Up button too many times, pushing the selected time beyond what the control system permits.

The dryer stops operating when the dt code appears, so it is not actively running in a failed state. It is safe to investigate the cause before restarting, but you should not attempt to repeatedly reset and run the dryer without addressing the underlying issue, particularly if the sensor bar is faulty, as undetected moisture readings could affect drying performance.

If cleaning the sensor bar resolves the issue, there is no parts cost. If the sensor bar needs replacement, parts typically range from $15 to $40 depending on the model, with professional labor adding $80 to $150 or more. A control board replacement, which is rarely needed for this code, can range from $100 to $250 for the part alone.

Yes, in many cases this is a DIY-friendly repair. Start by cleaning the moisture sensor bar inside the drum with rubbing alcohol to remove any residue coating. If the error returns, inspect the sensor bar for physical damage or a broken circuit. Avoid using the Adjust Time Up button excessively when starting a cycle, as that alone can trigger the code.

A reset may temporarily clear the dt code, but it will return if the root cause is not resolved. If the moisture sensor bar has an open circuit or is heavily contaminated, the dryer will encounter the same condition on the next cycle and display the code again. Fix the sensor bar condition or avoid excessive time adjustments before restarting.
