Symptom: Compressor Is Noisy

Possible Cause: Noise is normal (digital scroll compressors).
Corrective Action: Digital scroll compressors unload via a solenoid valve and motor sound will vary during loaded/unloaded states.
Possible Cause: Compressor is running backwards.
Corrective Action: Scroll compressors do not tolerate backwards operation. Rephase compressor for proper operation.
Possible Cause: Loose or damaged mounts/isolation.
Corrective Action: Verify compressor is mounted properly and internal isolation is not damaged.
Possible Cause: Unit and/or field piping was installed without proper vibration isolation.
Corrective Action: Install vibration isolation.
