bushman fridge runs every 5 mins?

Thanks for your replys, temp is set at 3 degrees and it operates a couple of degrees either side as outlined on their website, cycles as soon as the temp runs 2 degrees above set on the digital display, which is about every 4-5 mins & seemed to be too frequent considering ambient temps, we were hoping of some idea as we haven't owned a portable fridge before and appreciate the feedback.
