Abstract: A minimum off-time device according to the present invention that delays the restart of a compressor motor of a refrigeration system after power provided to the motor has been interrupted. The minimum off-time device is a standalone unit that is located outside the refrigeration system. The device is retrofitted to the refrigeration system by simply plugging the power line of the system into the device, which is then plugged into an AC wall receptacle, or alternatively, the device can be connected between the power line of the refrigeration system and an electrical circuit breaker panel. The minimum off-time device normally allows power from the AC power source to reach the refrigeration system. However, when a power interruption occurs at the AC power source, and subsequently, power is reapplied, the minimum off-time delay device immediately disconnects the refrigeration system from the AC power source and begins a timing sequence.
