Defective appliances are household devices that do not function as intended due to manufacturing errors or design flaws. These issues can lead to malfunctions, safety hazards, or reduced efficiency. Common examples include refrigerators, washing machines, and microwaves that may fail to operate properly. When an appliance is defective, it may require repair or replacement. Consumers often have the right to return or exchange defective products under warranty policies. Identifying a defective appliance early can help prevent further damage and ensure safety in the home.
