Midea SW1 STATUS CHECK status display

What it means

The outdoor SW1 button cycles through connected indoor units, temperatures, EXV positions, fan state, last error, and other service values. Those normal readouts are not standalone errors.

Urgency

Likely causes

Homeowner fix

Do not press outdoor-board controls unless you are qualified and the cabinet is safely accessed. Give your technician the indoor display code instead.

When to call a pro

No technician is needed for this status by itself. Call for service only if comfort is poor, water is present, or the indication never clears after conditions change.

Repair vs replace

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