Re: Diplomat 6842
John – Changing the thermostat is not too much of a job as long as you take things in stages with the power off. However, what you need to do is check and see if the appliance is switching on and off at all. On this unit the thermostat measures the temperature in the fridge although the priority cooling is in the freezer. If the temp in the fridge is not cold enough it could equally be that the compressor is failing or that the appliance is short of refrigerant. Equally, if your ventilation is not good, being a built in this could also be the cause.
