This sounds like this is a residential refrigerator powered by an inverter? What could be happening is it is being powered by an inverter, the inverter is overheating and shutting down allowing fridge to defrost then after the inverter cools off it comes back on and the ref. refreezes. I suggest looking into the power supply to the ref. and determining why the power is cycling on/off.
