Is it safe to put a freezer in cupboard?

No, it is not safe to put a freezer in a cupboard. A freezer is a large appliance that requires a lot of space and ventilation to function properly. Putting a freezer in a cupboard can block the vents and cause the freezer to overheat, which can be a fire hazard. Additionally, the cupboard may not be able to support the weight of the freezer, which could cause the cupboard to collapse.
