Freezer produces loud knocking or banging noises during compressor start or stop.

Safety first: Unplug the freezer before working at the rear. Do not attempt to open the sealed system.

• 1. Verify leveling: Adjust the front and rear feet so the freezer is stable and does not rock when pushed.
• 2. Check compressor bolts: Ensure the compressor mounting bolts are snug but not overtightened, and that rubber grommets are in place.
• 3. Isolate tubing: Gently reposition any refrigerant lines that may be striking the cabinet or each other when the compressor starts or stops.
• 4. Monitor over time: Some knocking is characteristic of certain compressors and may not indicate imminent failure. However, if noise worsens or cooling declines, contact a technician.
