A data logging module and a method of monitoring a medical warming cabinet is disclosed. A temperature of the heating chamber and a state of a door of the heating chamber are sampled at predetermined intervals and recorded as data packets on a memory device. A display may provide a message when the memory device is reaching capacity. Moreover, a selected of the data packets may be analyzed (such as the data packets excluding the data packets when the door is open) for the generation of a report. The data packets from the memory device may be transferred from the memory device to an external memory device as necessary.
