Hi Abbe, if you've been feeding your "old girl" twice a day at room temperature for a week now, it sounds like you may be essentially starting over rather than reviving. I would expect your starter to bounce back within a few days if it had only been challenged by your refrigerator failure, rather than dealt a fatal blow. On the other hand, neither sitting at 60 degrees for a few days or being frozen for a few days would normally kill of a well-maintained mature starter. Since you never saw any signs of mold or (I'm assuming) a pink or orange streak or tinge, it's certainly fine to continue feeding your starter until it returns to its normal aroma and rising behavior. At the very least I would recommend continuing until you get your dried starter up and running, as that process doesn't always go according to plan either. I'm sure one way or another you'll have the old girl back to baking soon!
