An apparatus and method for controlling the maximum stroke of a linear
compressor is provided. The shorting of the normal supply voltage of a
compressor to ground is used to detect overstroking. A plurality of
transistors are electrically coupled to the control circuit that is
electrically coupled to a linear compressor. When the compressor's stroke
exceeds it maximum stroke marked by the refrigerant barrel of the
compressor making physical contact with the armature, a signal is
received by the control circuit. The control circuit processes this
signal and sequences the transistors to return the extended stroke of the
compressor to its maximum stroke.
