Abstract: 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.
