    Samsung rf4287hars - lost refrigerant

    I am trying to fix a Samsung rf4287hars french door fridge. It lost the refrigerant, the low side pressure was negative, I added some refrigerant (R 134a) while running the pump, until low pressure became zero as the documentation said it should be. Total added was about 5 ounces. The fridge worked afterwards, with a fairly even frost pattern last I checked.

    Now the next step, locating the leak. Does anyone know, by chance, the typical leak locations in this or similar fridges? It seems those fridges have a very high failure rate, which leads me to believe that there is probably a common problem at a specific location.

    I have slight inclination to believe that the leak was at the low side as the fridge ceased working after being off for a couple months (which would've accelerated a low side leak).

    edit: and while I would rather pressure-test it with nitrogen I unfortunately don't have the necessary equipment.
