LG Dryer Error Code 5 Flashes

On an LG gas dryer, 5 Flashes indicates a loose or disconnected wiring condition, or an open circuit within the igniter, igniter sensing circuit, or voltage measurement circuit. The control module monitors these circuits during operation and shuts down when it cannot detect the expected signal. This fault is exclusive to gas models since it involves the gas ignition system.

No, you should not continue operating the dryer while this error is active. The 5 Flashes code means the igniter circuit is open or disconnected, which prevents the gas from lighting properly. Running the dryer under these conditions could allow unburned gas to accumulate, creating a safety hazard. Leave the dryer off until the fault has been diagnosed and repaired.

Repair costs depend on what component has failed. If only a wiring connector needs to be reseated, there may be no parts cost, though a service call fee typically applies. Igniter replacement parts generally range from around 15 dollars to 60 dollars depending on the model, with professional labor adding to the total. If the control module itself is involved, costs can range considerably higher, from 100 dollars to 300 dollars or more for parts and labor combined.

Some causes of this error, such as reseating a loose wiring connector, can be addressed without special tools. However, testing the igniter for continuity requires a multimeter and some comfort working around appliance components. Any repair involving gas components or internal wiring should only be attempted by someone confident in appliance repair, and gas line connections should always be handled by a licensed technician.

A reset may temporarily clear the displayed fault, but the error will return as soon as the control module runs its diagnostics again if the underlying problem has not been fixed. The 5 Flashes code will persist until the open circuit condition in the igniter or wiring is actually resolved. Resetting without repairing is not a solution.
