They don't go bad, but their texture and taste are poor after they've been thawed and then cooked. Blanch them first to inactivate enzymes that cause them to degrade to see if the resulting potatoes are acceptable to you.
*If you must refrigerate raw potatoes (eg, due to a lack of pantry storage space or hot, humid room conditions), the potatoes will last for about 3 to 4 weeks in the fridge, but will likely develop a sweet taste and darken when cooked; this effect can sometimes be offset by storing the potatoes at room temperature for a few days after removing them from the fridge.
