I think I see a problem here. The fridge is located in a garage that is below the inside temp of the fridge -it is a problem because it is not acting like a fridge anymore. The ventilation/cooling system shuts down because of low external temp and doesn’t provide the needed airflow for the moisture to be wicked away from the surface of the meat. Your fridge is simply acting like an insulated box with no heat exchange or ventilation. This is the reason the “bark” has not formed.
If you look closely at the instructions for the UMAi Dry they say not to dry age in garage fridges for this reason.
