There are a few possible reasons why your fridge might be turning on and off repeatedly. One possibility is that the temperature inside the fridge is getting too warm, causing the fridge to turn on in order to cool things down again. Another possibility is that there's something wrong with the fridge itself, such as a problem with the compressor or thermostat. If your fridge is turning on and off frequently, it's best to have a technician take a look at it to diagnose the problem.
