Common Mistakes to Avoid

1. Ignoring loose items on shelves or in crispers

Reason: Loose items like jars, bottles, or containers can vibrate and rattle against each other or the fridge walls, creating noise.
Solution: Securely rearrange items on shelves and in crispers, ensuring nothing is loose or can move around.

2. Overlooking leveling issues

Reason: An unlevel fridge can cause vibrations and rattling sounds as the motor tries to compensate for an uneven base.
Solution: Adjust the fridge's leveling feet until it sits perfectly level on the floor.

FAQs

My fridge freezer is rattling, but only when it's running. What could be causing this?
A rattling sound during fridge operation often points to loose internal components. Check for items touching the back wall, loose shelves or drawers, or possibly even something small caught in the fan motor. Try gently rearranging items and tightening any loose screws you find.
I've checked everything inside, but the rattling persists. What else could it be?
If the noise originates from the outside of the appliance, the problem might be related to the compressor or its mounting. It could be a loose compressor mounting bolt, or even something as simple as the fridge not being level, causing vibration. If you're uncomfortable checking these components yourself, it's best to contact a qualified appliance repair technician.
