Symptom
Indoor unit leaks water from the front or bottom of the casing during cooling operation.
Condensate Drainage Failure
Symptom
Loud rattling or buzzing noise from indoor unit during operation.
Indoor Mechanical Vibration / Loose Components
Symptom
Outdoor unit makes loud grinding or squealing noise when running.
Outdoor Fan Motor Bearing Failure
Symptom
Outdoor unit runs but indoor unit fan stops intermittently, causing uneven cooling.
Indoor Fan Intermittent Operation
Symptom
Remote control does not operate the indoor unit, but unit can be controlled from the front panel (if available).
Remote Control / IR Receiver Failure
Symptom
Unit frequently turns on and off (short cycling) without reaching set temperature.
Short Cycling / Control Instability
Symptom
Unit operates but causes excessive vibration and noise transmitted through the wall or floor.
Installation Vibration / Mounting Issues
Symptom
Unit powers on but compressor and outdoor fan never start; only indoor fan runs.
Outdoor Unit Not Responding
Symptom
Unit trips the circuit breaker immediately or shortly after starting.
Electrical Short / Overcurrent
Symptom
Unit will not power on at all; no lights or display on indoor unit.
