It will be the thermostatic switch only about 15 quid, it is very prone to vibration as mine packed up after moving house. any universal thermostat will repair your unit, all in all a 30 min job. you can prove it is not the pump by bypassing the thermostat, it is located behind the plastic suround just as you open the door, a capillary temperature sender is attached and runs down the back of the fridge where it is screwed to the heat exhanger (the big flat plate at the back of the fridge)
Good Luck
