Troubleshooting
Symptoms: Unit does not start
Possible Causes: MCB has tripped
Suggested Remedy: Reset MCB
Symptoms: Fuse has burnt
Possible Causes:
- Input voltage to the stabiliser is below acceptable range
- Replace fuse wire
Suggested Remedy:
- If the input voltage to the stabiliser is below the acceptable range, the airconditioner will not turn on
Symptoms: Unit does not cool even after the normal time delay of approx. 2 minutes
Possible Causes:
- Compressor is off (not in Auto or Cool Mode)
- The airflow paths of either or both the indoor & outdoor units are not free
- The air-filter is not clean
Suggested Remedy:
- Use the remote to turn the compressor on
- Remove all obstructions to make the airflow paths free
- Clean the air-filter
NOTE: If the unit still does not work, or if any other types of symptoms are encountered, shut off the mains (switch fuse unit) and call the service engineer/technician.
