Troubleshoot Appliance Noise & Vibration
Unusual squealing, grinding, heavy thumping, or severe vibrations indicate mechanical stress that can lead to permanent component failure. Our Lawrenceville repair specialists pinpoint and resolve the root cause quickly.
Washer & Dryer Rattles
Worn tub bearings, unbalanced drum shafts, broken shock absorbers, and motor pulleys.
Refrigerator Buzzing & Hum
Evaporator fan blade obstructions, compressor motor strain, or vibrating condenser coils.
Dishwasher Grinding
Circulation impeller debris, hard food chopper failures, and drain pump blockages.
Appliance Noise & Vibration Guide
Identify grinding, squealing, and violent shaking before minor mechanical wear turns into total motor or tub failure.
Heavy metal-on-metal friction usually points to worn drum bearings, failed pump impellers, or worn motor shaft assemblies.
High risk of damaging the tub or burning out the drive motor if run continuously.
Rhythmic high-pitched squeaks often come from dried-out idler pulleys, worn drum support rollers, or condenser fan motor bushings.
Gradual friction buildup can cause drive belt snapping or fan motor lockup.
Violent unit movement during spin or cooling cycles is caused by broken shock absorbers, failed suspension springs, or unbalanced leveling feet.
Can crack internal drain tubs, dent outer cabinets, or damage residential flooring.

Common mechanical causes and troubleshooting steps
A loud roaring sound that gets louder as the spin speed increases is the textbook symptom of failed rear tub bearings. When the waterproof tub seal deteriorates, water penetrates the steel bearings, washing out the grease and causing rust. Replacing the bearing kit or the rear outer tub assembly resolves this before the inner stainless basket gets off-center.
