Genuine Daikin 6023926 Indoor Fan Bearing Mounting Plate is the mounting plate that locates and secures the indoor fan bearing, holding the fan shaft in correct alignment. When it is bent, cracked, or missing, the bearing can sit out of alignment and the fan can run noisily or wear early. A genuine plate locates the bearing the way your Daikin expects — where a non-genuine part can fit poorly and let it move.
