Repairing appliances involves diagnosing and fixing issues with household devices like refrigerators, washing machines, and microwaves. Common problems include electrical failures, mechanical malfunctions, and worn-out parts. Repairing these appliances can often save money compared to buying new ones. To repair an appliance, one typically starts by identifying the problem, which may require tools like screwdrivers and multimeters. Once the issue is found, it may involve replacing parts or making adjustments. For complex repairs, hiring a professional technician can ensure the appliance is fixed safely and effectively.
