Freezer makes loud buzzing or humming noise, especially from the back.

Safety first: Unplug the freezer before accessing the rear compartment.

• Step 1 – Inspect condenser fan: Remove the rear access panel and check for debris in the fan blades. Remove any obstructions.
• Step 2 – Check fan mounting: Ensure the fan motor is securely mounted and not loose or rattling.
• Step 3 – Isolate vibrations: Gently move refrigerant lines away from cabinet surfaces and secure with foam or clips where they may be vibrating.
• Step 4 – Evaluate compressor noise: Some humming is normal, but loud grinding or knocking indicates compressor wear. Compressor replacement is a professional repair.
