Type: PG (Pulse Generator) Indoor Fan Motor

• 1.【Direct Replacement for Shinco Wall-Mounted AC Units】:This indoor fan motor is engineered as a drop-in functional alternative for specific Shinco residential split-system air conditioners. Matching the 2301-26421KB and YYR16-4A21-PG model designations, it serves as the ideal service part to restore normal indoor airflow when the original PG (Pulse Generator) motor fails due to worn bearings, seized shaft, or winding burnout
• 2.【Reliable PG Motor with Hall Effect Speed Feedback for Precise Control】:The YYR16 series PG motor is equipped with a built-in Hall effect sensor that generates real-time rotation pulses (typically 3 Hall pulses per revolution). This feedback allows the indoor control board to monitor the motor‘s speed continuously and automatically adjust the voltage to maintain consistent airflow, preventing common issues like blocked operation and safeguarding the drive circuit
• 3.【Plastic-Encapsulated Sealed Construction for Maintenance-Free Operation】:Unlike exposed motors, this YYR16-4A21-PG unit features a durable plastic-encapsulated overall sealed housing. This design permanently protects the internal windings from dust and moisture ingress. Importantly, it is pre-lubricated at the factory and requires no additional oiling, ensuring years of quiet, reliable service in residential environments
• 4.【Precision Shaft and Dimensions for Multiple Shinco Models】:The 2301-26421KB motor is built to OEM specifications, featuring a precision shaft and standardized mounting bracket holes to fit a wide range of Shinco 1-1.5HP wall-mounted AC units. It offers flexible variable speed control (High, Medium, Low, Silent) to match the speed settings of your original remote control, ensuring even room temperature distribution with low operational noise
• 5.【Critical Service Component for Fixing Indoor Fan Failures】:This PG replacement motor is a critical service part for HVAC technicians. It is the ideal repair solution when your AC unit shows classic fan motor failure symptoms, including the fan not starting at all, the fan spinning too slow even on high speed, excessive grinding or rattling noise, or a loud “humming” sound followed by an overload protection trip
