on your model the thermostat is sensing the temperature in the fridge only.some thermostats are just pushed down a hole and will go to a stop point.others are mounted to the air vent at the back.not sure which yours is.pull the old seal back away from the plastic inner door liner.is there any screws?.no screws is a sealed unit and will require a replacement door as there isn't any fixings for a universal one unless you do a diy job on it.be aware new doors can be a different colour when fitted!!
compressors last as long as they last.gas loss or system blockage is more common failure issue.on you model auto defrost is the biggest issue
