It is possible for a dehumidifier to overload or damage your electrical circuit or outlet, particularly if the unit is not properly maintained or if the outlet is overloaded with other devices. Most dehumidifiers require a significant amount of power to operate, particularly when running at full capacity. If the electrical circuit that the dehumidifier is connected to is already overloaded with other devices or appliances, this can increase the risk of an electrical overload, which can cause damage to the circuit or outlet, or even start a fire. Make sure the outlet you are using is rated for the power needs of your dehumidifier in order to avoid overloading. The power specifications are listed on the dehumidifier's label or in the user guide. Using extension cords or power strips with your dehumidifier is also not recommended because they increase the risk of overloading.
