The customer reported that their mini-split was heating properly but would shut off for approximately 10 minutes while the indicator light blinked before resuming operation. I explained that this is normal winter operation, as the outdoor unit periodically enters a defrost cycle. I tested the discharge air temperature and confirmed that the mini-split is heating as expected. I also verified that the unit is correctly entering defrost mode. All components of the system are operating as they should at this time.
