For future reference, you want the fridge to stay below 40° F and the freezer to stay below 0° F and blackouts are a good excuse to have fridge/freezer thermometers in hand. I dunno how I could feel secure about my fridge without those thermometers stuck in there. Even when there’s power, the thermometers in there are good for temperature and energy management — I want to keep the sections just below the high limits of 0° and 40° but I don’t want to spend more energy than I have to.

As for blackouts, immediately transfer the all the ice in the freezer into a container in the fridge and that will help maintain that lower temperature. Once you find grocery stores in your area that are open and able to sell ice, buy ice as needed to keep the fridge cold.

Hope this helps for the future and stay warm, *hugs*
