CORONA Mini-Split Air Conditioner Outdoor Unit COH-U4019R Fan Running & Equipment Interior

I disassembled a COH-U4019R, an outdoor unit of a Corona air conditioner, and took pictures of the inside of the equipment, focusing on the fan operation.

The fan has a very simple shape, which is rarely seen in recent years, and the fan motor, although a BLDC motor, has the appearance of an AC motor, which is not often seen in other companies.

The fan speed seems to be set relatively low for recent models, but compared to the COH-U2819R uploaded earlier, this model seems to have a slightly higher fan speed.

Also, note the structure of the machine room compared to the COH-U2819R uploaded earlier.


0:00- Propeller fan operation and inside the equipment
4:21- Fan speed change with power save setting (usually ↔︎ power save)
5:59- Operation stopped
6:30- Fan detail and fan motor operating alone
