Abstract
A wound bobbin coil (A) and a fuse (B) are interconnected electrically in series. The coil and the fuse are mounted closely adjacent and molded into a tough, nylon encapsulation (C). The series connected coil and fuse are connected with electrical terminals (26, 30) to form a unitary electrical component which is readily connected with associated circuitry. In this manner, when the coil becomes damaged sufficiently to blow the fuse, both the coil and the fuse must be replaced. A repairman cannot short the fuse or merely replace the fuse and allow a damaged coil to continue functioning. In the preferred utilization of the present coil in a freezer compartment ice maker, coil failures can cause flooding, overheating, and other catastrophic damage to a refrigerator/freezer.
