So far, so good. It's been running for about 2 hours. The refrigerator section is COLD. Frost continues on the coils. Freezer fan is working and freezer is working normally. That very warm draft I felt coming out of the grill originally has been replaced with a much cooler, strong breeze. If anything, that vacuuming of the coils certainly increased airflow greatly.
