- Heat & Blockage: As mentioned, the refrigerator generates heat. When you place another appliance on top, you block the critical ventilation the fridge needs. This forces the fridge to run constantly, increasing its internal temperature and risking damage to the motor.
- Safety Hazard: Both appliances will be forced to work harder, which significantly increases the risk of overheating, electrical failure, and even fire.
Better option: Keep all small appliances on a sturdy, dedicated countertop or shelf with plenty of open space around them for proper airflow.
