LG Mini-Splits Repair

Multi V VRF System

Common symptoms: One or more zones stop responding, central controller logs a communication error, or the outdoor unit trips on a fault shortly after starting.

Likely causes: Indoor thermistor fault, communication wiring issue between indoor and outdoor units, or an inverter compressor overcurrent fault.

What we check first: Zone-by-zone communication status, thermistor readings, and outdoor unit inverter fault history.

What work is done: Thermistor replacement, communication wiring or board repair, and inverter module diagnostics or replacement.

When to call: If one or more zones stop responding or the outdoor unit repeatedly trips after starting.
