Possible Causes
Failed compressor start winding, Open thermal overload, Bad dual run capacitor, Faulty contactor not delivering full voltage to compressor
How to Fix / Troubleshooting
Danger: High voltage and high current. Turn off power at the disconnect and breaker before opening the unit.
- 1. Listen for compressor: With the unit running, if you hear only the fan and no compressor hum, suspect the capacitor or compressor.
- 2. Inspect capacitor: Remove the service panel and check the dual run capacitor for bulging or leaks. Replace if deformed, matching microfarads and voltage.
- 3. Check wiring: Ensure compressor leads are firmly connected to the contactor and capacitor.
- 4. Professional testing: If the compressor still does not start, a technician should test compressor windings, measure amp draw, and determine if a hard-start kit or compressor replacement is needed.
