How to Fix / Troubleshooting
Safety first: Unplug the unit before accessing the compressor compartment.
- 1. Check leveling:

- Remove the rear panel and inspect compressor mounting bolts and rubber grommets.
- Tighten loose bolts and replace damaged grommets.
- 3. Secure tubing:
- Look for copper refrigerant lines touching the cabinet.
- Gently bend or pad lines so they do not contact metal surfaces.

- If the noise is extremely loud or accompanied by poor performance, the compressor may be failing and should be evaluated by a technician.
