Mitsubishi Electric LED1 LIT AND LED2 LIT status display

What it means

LED1 lit and LED2 lit is the normal outdoor control board indication for this MXZ-D table. It is not an error by itself.

Urgency

Likely causes

Homeowner fix

No repair action is needed if the system is operating normally.

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.
