Goodman outdoor condenser fan runs but compressor does not start
Safety Warning
This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.
If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Safety first: Turn off power at the outdoor disconnect and breaker. Capacitors can hold a charge; do not touch terminals without proper discharge and training.
Steps to check (visual):
- 1. Listen for compressor: With the thermostat calling for cooling, you may hear a brief hum or click from the compressor. A loud hum with no start often indicates capacitor or mechanical issues.
- 2. Inspect capacitor: Locate the dual run capacitor in the Goodman condenser. If the top is domed or there is oil leakage, it is likely failed and should be replaced with the exact µF and voltage rating.
- 3. Check contactor: Inspect the contactor for burnt or pitted contacts. If the contactor coil is not pulling in when there is a call for cooling, the coil or control signal may be faulty.
When to call a professional: Testing compressor windings and replacing capacitors or contactors should be done by a qualified technician to avoid shock and ensure correct parts.
