The embodiments of the present disclosure provide a heating control method, a heating control device, and an ice maker. The heating control method comprises: determining that the ice maker is in an ice-making operation state; acquiring a first heating strategy of a target part of the ice maker according to a preset first heating strategy acquisition rule, based on ambient parameter information of an ambient in which the target part of the ice maker is located; and heating the target part based on the first heating strategy. Through the embodiments of the present disclosure, the problem that the deicing heating control technology of the ice maker in the prior art has high energy consumption is solved, and the beneficial effect of precise and low-energy deicing heating control on the ice-prone parts of the ice maker is achieved.
