ActronAir Indoor Evaporator Fan Deck 9x7 S 600W is the standard-wattage 9x7 fan deck for Classic Series residential split ducted systems, balancing airflow volume and motor current draw for typical residential duct configurations. A degraded run capacitor is the most common cause of fan deck failure before motor winding burnout -- inspect and replace the 15uF capacitor whenever the fan deck is replaced. Isolate power at mains before replacement -- live work on fan assemblies is dangerous and must only be performed by a qualified technician.
