Possible Causes

No power to outdoor unit, Tripped outdoor breaker or blown fuse, Faulty outdoor main PCB, Broken communication cable between indoor and outdoor units

How to Fix / Troubleshooting

Safety first: Turn off all related breakers before opening the outdoor unit.

Steps to check:

  • 1. Verify outdoor power: Check the dedicated breaker or disconnect for the outdoor unit. Reset if tripped, but if it trips again, leave it OFF and call a technician.
  • 2. Inspect outdoor terminal block: With power OFF, open the outdoor panel and ensure supply wires are tight and not burnt.
  • 3. Check communication cable: Confirm the interconnecting cable between indoor and outdoor units is intact and correctly wired.
  • 4. Listen for relay click: When the indoor unit calls for cooling, you should hear a faint click from the outdoor PCB relays (if safe to listen with cover on). No sound may indicate PCB failure.

When to call a technician: If power and wiring are correct but the outdoor unit remains inactive, the outdoor PCB or compressor contactor may be defective.
