A motor control apparatus for controlling a motor is provided. The motor has an output power stage and a relay allowing power to be connected to the output power stage. The apparatus comprises a microprocessor providing a PWM cycle delivered through a capacitor to a transistor. The microprocessor activates the transistor for a first predetermined amount of time during the PWM cycle causing the relay to actuate the output power stage thereby driving the motor. A detection mechanism within the microprocessor for detecting a fault in the main output transistor. The circuitry disengages the relay from the output power stage thereby causing the motor to cease being driven.
