LG Dryer Error Code 25

Error code 25 on an LG dryer indicates a power supply issue caused by an incorrect or loose wire connection. The dryer's control system has detected that the electrical wiring does not match the expected configuration or is not making proper contact. This can involve the power cord terminal block, internal wiring harnesses, or the household outlet supplying power to the unit.

Yes, a loose or incorrectly wired power connection can pose a fire or shock hazard and should not be ignored. Do not continue operating the dryer until the wiring has been inspected and corrected. Always disconnect power to the unit before examining any internal wiring or terminal connections.

If the repair only involves reseating a loose connector or correcting a wiring configuration, the cost can be minimal, essentially just the time for a service call, which typically ranges from $75 to $150. If wiring components, a terminal block, or a harness need to be replaced, parts and labor together could range from $100 to $300 depending on the extent of the damage and local labor rates. Getting a diagnostic visit from a qualified technician will give you a more accurate estimate for your specific situation.

Start by disconnecting power to the dryer, then inspect all wiring connections at the terminal block, control board, and internal harness connectors for looseness or incorrect placement. Verify that the power outlet is supplying the correct voltage and is wired with proper polarity. If a connection is found loose, reseat it firmly and restart the dryer to see if the code clears. If wiring is damaged or incorrectly configured, it will need to be corrected before the dryer will operate normally.

A simple reset by unplugging the dryer and restoring power is unlikely to permanently clear error code 25 if the underlying wiring issue has not been resolved. The code is tied to a physical condition in the wiring, so it will typically return as long as the loose or incorrect connection remains. The wiring must be inspected and corrected to resolve the fault.
