Dough froze in fridge

My cheap garage fridge every once in a while will drop temp dramatically. Maybe when not too full and weather heats up, not really sure why. My dough balls were in there when this happened on day one of a 2-3 day CF. One of the 3 was pretty much all the way frozen the other 2 were still a bit soft. I adjusted fridge and left dough alone. How do you think this will affect my usual process of 2-3 day CF and 3-5 hours of balls sitting at RT?
Thanks
