ActronAir Indoor Fan Motor suits LRE-100AS is the genuine replacement indoor fan motor for the LRE-100AS Ultra Slim ducted indoor unit, providing the motor drive for the indoor fan wheel that circulates conditioned air through the unit's compact coil and into the connected duct system. A failed indoor fan motor on the LRE-100AS causes complete loss of airflow through the indoor unit and triggers high discharge temperature protection -- fit the 100% Genuine ActronAir LRE10008 to restore factory fan operation. Isolate power at mains before replacement -- live work on fan assemblies is dangerous and must only be performed by a qualified technician.
