They don't last long around my house. If you can stand to not use them in potato pancakes or just reheat them within a week, they should go in the compost. This is assuming that your fridge is around 38 degrees Fahrenheit. Before you eat them, heat them to 140 throughout.
Try this instead: take the leftovers while they are still warm but not hot. Add an egg for each cup of potatoes and maybe a pinch of garlic salt. Mix with a fork. Patty them out in third to half cup amounts (about the size of a burger patty) and freeze them with wax paper between them, tightly wrapped in plastic wrap. When you are having eggs next weekend, treat yourself to a potato pancake.
Mashed potatoes keep well frozen too, whether pancake or just tightly covered you can expect about 6 weeks of freezer time without degradation.

Can boiled potatoes left out at room temperature for three weeks develop harmful mold?
Boiled potatoes could develop harmful mold even in a refrigerator, in a period of 3 weeks. That is a very long time to store boiled potatoes (unless frozen, which is safer). Three weeks at room temperature is far too long for boiled potatoes (although raw potatoes can last that long).
A freshly cut potato turns brown when left standing. Why do mashed potato stay white?
They will also turn brown if left exposed to the air long enough. The browning is oxidation. Plain raw potatoes that are sliced so the inner starch is exposed to the oxygen in the air will 'rust' or turn brown. Mashed potatoes are cooked and have other ingredients added to them like salt, butter, milk, etc. This cooking and the additives helps preserve the potatoes from oxidation for a longer period of time.
What could cause mashed potatoes to stink?
Bacteria. Specifically S.pyogenes. This bacteria is present in the environment, and loves to grow on the starch in potatoes and rice. Don't leave your potatoes out of the fridge uncovred for too long, and definitely do not eat potatoes that have been in the fridge for more than a week. i won't even eat refrigerated mashed potatoes after 3 days.Other bacteria will also infest mashed potatoes if you put dairy in it, and the dairy will sour just as milk does after staying in the fridge for too long. No more than three days storage for potatoes with dairy. When you reheat do it in the oven or stove top. reheating potatoes in the microwave typically does not keep them hot enough for long enough to kill the bacteria.The good news is majority of the "food poisoning" you would get from typical potato bacterias would only last 12-24 hours...
Are roasted potatoes left out of the refrigerator all right to eat?
That depends how long they were left out of the fridge. Potentially hazardous food should not be unrefrigerated for more than 2 hours. If the ambient temperature is very warm, then cut that to 1 hour.
How long do you boil potatoes if you plan on making mashed potatoes?
Mashed Potatoes!!About 20 minutes, depending on the size of your potatoes. Start off by putting the potatoes on in cold water (root vegetables should always start in cold water, other vegetables in boiling water). The way to test their doneness is to insert a sharp knife into a few of your potatoes and lift them up out of the water. If they fall off the knife, they're done.
