LG DEFROST status display

What it means

Defrost is a normal heating-cycle status. LG says the system may briefly run in cooling mode to warm the outdoor unit and melt frost while the indoor fan pauses.

Urgency

Likely causes

Homeowner fix

Wait several minutes for defrost to finish. Keep snow and loose debris away from the outdoor unit, but do not chip ice from the coil or open the cabinet.

When to call a pro

Call for service if Defrost never clears, the outdoor unit is encased in ice, or heating does not resume after the cycle.

Repair vs replace

This is a normal operating display, not a repair-or-replace decision.
