description A circuit is provided for powering a small electrical appliance load. In one embodiment the circuit includes a power output control device such as a triac to supply power to the load. A thermal fuse is placed in series with the triac. A resistor is placed in thermal proximity to the thermal fuse. A switching device such as a transistor is provided to turn on the resistor. A microcomputer controller monitors a short fault condition of the triac. The microcomputer controller turns on the transistor upon detecting a short fault condition in the triac.
