The slight buzzing sensation you experience while handling pots/pans on a cracked, glass top induction stove is likely due to the electromagnetic fields generated by the induction cooktop. This buzzing is a normal characteristic of induction cooktops and not necessarily an indication of danger.
However, when the glass top of an induction cooktop is cracked, it should be taken seriously and repaired or replaced promptly. Cracks in the glass can compromise the electrical and structural integrity of the cooktop, potentially leading to safety hazards.
While the buzzing itself is not likely to cause electrocution, the cracked glass could expose the internal electrical components to moisture, liquids, or other foreign materials, increasing the risk of electrical malfunction, short circuits, or electric shock. Moreover, if the crack worsens or spreads, it might eventually lead to more significant safety issues.
It is essential to avoid using a cracked induction cooktop and to have it inspected and repaired by a qualified technician or replaced with a new unit to ensure safe operation. Safety should always be a priority when dealing with electrical appliances, and any damage should be addressed promptly to prevent potential risks to users.
