Troubleshooting guide
AC Unusual Noise
Rattling, grinding or buzzing can indicate loose panels, fan issues or electrical faults and should be inspected.
Possible causes
Rattling, grinding or buzzing can indicate loose panels, fan issues or electrical faults and should be inspected. Other causes may be possible; a technician needs the exact brand, model and symptoms to narrow them down.
Safety note: Do not remove covers or attempt electrical, refrigerant or high-voltage repairs. Disconnect power only when safe, and contact a qualified technician if the issue persists.
When to request service
Request an inspection if the problem continues after the basic checks, repeats, shows an error code, trips power, leaks, smells burnt, or involves internal components.
