Fault diagnosis

- Indoor fan, louvre or sensor faults
- Drain blockage and water leakage
- Outdoor PCB, compressor or fan faults
- Multi V communication and refrigerant issues
How diagnosis is handled
For LG systems, we combine the displayed error code with live operating checks. Electrical supply, communication, sensor resistance, fan feedback, system pressure and temperature differences are checked before a repair quotation is issued.
Multi V repairs can involve several connected indoor units. A structured diagnosis helps avoid replacing a component on the wrong unit and allows the technician to identify whether the root cause is controls, refrigerant distribution, airflow or the common outdoor system.

Customer questions
Frequently asked questions
Do you repair LG air conditioners?
Yes. Topworks provides inspection, fault finding, servicing and repair support for LG split, commercial and Multi V VRF systems. Parts availability and repair viability are confirmed using the model and serial information.
How much does a LG aircon service cost?
A standard wall-split major service is normally estimated at R750–R1,200. Cassette, ducted, VRF and chiller systems cost more because access, size and testing requirements differ.
Can you repair a LG aircon that is not cooling?
Yes. The technician checks airflow, coils, fan operation, sensors, electrical controls, refrigerant pressure and signs of leakage before recommending gas or replacement parts.
Do you install new LG systems?
Installation can be quoted after confirming capacity, pipe route, drainage, electrical supply, outdoor-unit position and equipment availability.
Do you offer commercial maintenance for LG?
Yes. Planned maintenance can be arranged for offices, retail, hospitality, healthcare, industrial and multi-unit sites after an equipment survey.
