LG Dryer Error Code d-

The d- code on an LG dryer indicates a display PGM error, meaning the display control board has encountered a programming fault or has entered a programming mode. This is a control system issue rather than a mechanical problem. The dryer may be unresponsive to inputs while this code is active. A power reset is the first recommended step.

A hard power reset by unplugging the unit will clear the d- code if it was triggered by a temporary condition such as a power surge or momentary voltage drop. If the display board has a permanent programming failure, the code will return after the reset. Repeated reappearance of the code after power cycling is a strong indicator that the board itself needs to be replaced.

If a power reset resolves the issue, there is no parts cost involved. If the display control board requires replacement, parts alone typically range from $50 to $200 depending on the specific model. Adding professional labor, total repair costs generally fall between $100 and $350. Diagnosing whether the display board or the main control board is at fault before ordering parts can help avoid unnecessary expenses.

Start by unplugging the dryer from the wall outlet for at least 5 to 10 minutes, then plug it back in to perform a hard reset. This can clear a temporary programming state caused by a power fluctuation. If the code returns immediately or the dryer remains unresponsive, the display control board may need to be replaced, which requires basic disassembly skills and component sourcing.

It is not recommended to attempt to operate the dryer while the d- code is active. The control system may not process cycle inputs correctly, and the dryer may behave unpredictably. Address the code before resuming normal use to avoid any risk of incomplete or uncontrolled operation.
