Possible Causes
Open compressor winding, Tripped internal thermal protector, Faulty inverter module, Loose compressor wiring connector
How to Fix / Troubleshooting
Safety first: Turn OFF power before opening the outdoor unit. Compressor terminals carry high voltage.
- Step 1 – Listen for compressor: With the unit running, listen closely. If you only hear the fan and no deeper hum, the compressor is not starting.
- Step 2 – Visual wiring check: With power OFF, inspect compressor wiring connectors for looseness or burning.
- Step 3 – Allow cool‑down: If the compressor was very hot, allow it to cool for at least 1 hour and try again once.
- Step 4 – Technician diagnosis: A technician must test compressor windings, check for DC output from the inverter, and may need to replace the compressor or outdoor PCB.
