LG Dryer Error Code 6 Flashes

The 6 Flashes code on an LG gas dryer indicates a problem in the gas ignition system, specifically pointing to an inoperative gas valve, a failed flame sensor, or loose and disconnected wiring connecting these components to the control module. The dryer cannot confirm that the burner has ignited, so it shuts down the heat circuit and displays this fault. The drum may still spin, but no heat will be produced until the fault is resolved.

You should not continue operating the dryer in an attempt to force a heat cycle when this code is active. The fault indicates a breakdown in the gas ignition control system, and attempting to override it could result in unignited gas accumulating inside the appliance. Power the unit off and leave it off until the root cause has been identified and corrected.

Repair costs vary depending on which component has failed. A replacement flame sensor or igniter is generally an inexpensive part, with DIY costs typically in the range of $15 to $50 for the part alone. A gas valve replacement is more expensive, with parts ranging from $40 to $120 or more, and professional labor adds to that cost. If the control module is the cause, total repair costs including parts and labor can range from $150 to $350 or higher depending on the service provider.

A knowledgeable DIYer can begin by checking all wiring connections at the gas valve, flame sensor, and control module for security and corrosion, which requires no replacement parts. If wiring is intact, replacing the flame sensor or igniter is a moderately approachable repair. However, any work involving the gas valve or gas supply line should be handled by a qualified technician, since improper repairs can create a gas leak hazard.

Unplugging the dryer for a few minutes and restarting it may temporarily clear the code, but if the underlying problem with the gas valve, flame sensor, or wiring has not been fixed, the fault will return as soon as the dryer attempts to heat again. A reset is useful for confirming whether the issue is intermittent, but it is not a repair and should not be relied upon as a solution.
