Possible Causes

How to Fix / Troubleshooting
Safety first: Turn OFF power. High voltage and high pressure are present in the outdoor unit.
- Step 1 – Listen for compressor: If only the fan noise is heard and no compressor hum or vibration, the compressor is not starting.
- Step 2 – Do not attempt to jump-start: Do not short terminals or use oversized capacitors; this is dangerous.
When to call a technician: Compressor start issues require electrical testing and should be handled by a qualified technician.
