A sensor element is attached to the appliance to obtain movement and magnetic field data from the appliance. The sensor element can be attached to the metal shell of the appliance. A base sensor component receives data from the sensor element, and then divides individual signals into sub-frequencies. In one embodiment, 3-D signals relevant to position change, acceleration, and detected electromagnetic field at the sensor are all analyzed by the base sensor, along with a current draw signal for the appliance. Changes in the signals are reported to a server, that compares changes to a prepopulated database. This database correlates changes in sensor signals with predicted failures of appliance components. Identified components with a predicted, future failure are replaced before the failure. ## Claims ### Claim 1 A system comprising: a) a remote sensor configured to be attached to a wall of an appliance, the remote sensor having: i) a position sensor generating a physical movement signal, and ii) an EM field sensor generating an electromagnetic field signal;
