Daikin DEFROST status display

What it means

Defrost is a normal heating-cycle status. The indoor fan may pause, the outdoor unit may steam, and warm air should resume after the cycle finishes.

Urgency

Likely causes

Homeowner fix

Let defrost finish. Keep the outdoor unit clear of snow buildup around the base, but do not chip ice from the coil.

When to call a pro

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

Repair vs replace

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