It is generally not safe to put a mini refrigerator directly under an induction cooktop, even with a gap of 15 cm. There are a few reasons for this:
Heat: Induction cooktops generate heat during operation, and this heat needs space to dissipate properly. Placing a refrigerator directly underneath the cooktop can inhibit the heat dissipation process, potentially leading to overheating of the refrigerator.
Ventilation: Refrigerators require proper ventilation to dissipate heat generated by the cooling system. Placing a cooktop above the refrigerator can obstruct the ventilation, which can negatively impact the refrigerator's performance and potentially cause it to overheat.
Safety hazards: Induction cooktops can generate strong electromagnetic fields during operation. Placing a refrigerator underneath the cooktop can expose the refrigerator to these electromagnetic fields, which can interfere with its electronic components and potentially cause malfunctions or damage.
To ensure safety and proper functioning of both appliances, it is advisable to maintain sufficient space and separation between a refrigerator and an induction cooktop. It is best to consult the manufacturer's guidelines and follow their recommended clearance requirements for both appliances. If you have limited space, consider reconfiguring the placement of the appliances or seeking professional advice to ensure proper installation and safety precautions.
