Wine cooler making loud humming or buzzing noise from rear

Safety: Unplug the unit before accessing the rear. Do not touch the compressor immediately after running; it can be very hot.

• Step 1 – Isolate noise source: Remove the rear panel and briefly power the unit to determine whether the noise comes from the fan or compressor. Then unplug again.
• Step 2 – Check fan: Inspect the condenser fan for debris or bent blades contacting the shroud. Clean and straighten as needed. If the fan is still noisy or wobbles, replace the fan motor.
• Step 3 – Inspect compressor mounts: Check rubber grommets under the compressor. If they are cracked or missing, replace them to reduce vibration.
• Step 4 – Compressor noise: If the compressor itself is loud and the noise has worsened over time, a sealed system technician should evaluate for internal wear.
