remove the thermostat housing and try pulling the capillary out of the side tube/insulation.if it comes out fit a new stat.I always order the correct stat against the PNC number
airflow housing is where the end of capillary may be mounted at the back of fridge inside (interior).will have a slider switch with MAX/MIN written on it.pop 2 plastic blanking caps out and then undo screws down holes and remove unit.As I said before not 100% sure if yours will be like this or not??
