Symptoms
- Unit rocks or wobbles when touched
- Buzzing or rattling that changes with vibration
- Vibration transfers to the floor or nearby items
- Noise is worse when the compressor is running
Likely causes
- CommonUnit not level on the floorAn uneven surface or unadjusted leveling legs makes the whole cabinet rock as the compressor runs.
- CommonLoose compressor mounting or shipping bolts left in placeShipping bolts meant to be removed before use can cause vibration if left in, or mounts can loosen over years.
- PossibleItems inside vibrating against walls or shelvesLoose bottles or containers can rattle and amplify the sense of vibration.
- PossibleWorn compressor mountsRubber isolation mounts under the compressor can degrade, transmitting more vibration to the cabinet.
What to do
- Use a level to check the unit front-to-back and side-to-side, adjusting the leveling legs or feet as needed.
- Check under the unit for any leftover shipping brackets or bolts that should have been removed at installation.
- Open the freezer and secure any loose items that might be rattling against the interior.
- Gently rock the unit by hand to see if the vibration is from the cabinet itself or transmitted from the floor.
- If the floor is uneven (common in garages), consider anti-vibration pads under the feet.
- If vibration persists despite leveling and no loose shipping hardware, have a technician check the compressor mounts.
