Could a failing Auger Pulley cause the RYOBI 40V BRUSHLESS SNOW BLOWER to have symptom: Snow Blower Auger Stalled?

This part features a steel insert keyed into a plastic housing; the plastic keyway frequently shears under the high torque required to move heavy snow. When this interface fails, the drive belt loses the ability to turn the auger, causing the assembly to 'stall' mechanically even if the motor continues to rotate.

Could a failing Main Control PCB Assembly cause the RYOBI 40V BRUSHLESS SNOW BLOWER to have symptom: Snow Blower Auger Stalled?

The brushless motor controller is susceptible to thermal shock and moisture ingress, leading to MOSFET failure. If the controller detects an abnormal current draw or a timing error from the Hall effect sensors during auger engagement, it will initiate a safety shutdown, resulting in a total unit stall.

Could a failing Auger Drive Belt cause the RYOBI 40V BRUSHLESS SNOW BLOWER to have symptom: Snow Blower Auger Stalled?

As a sacrificial friction component, the belt can stretch or glaze over time, especially during heavy loads. If the belt slips significantly, the reduction in RPM may be detected by the electronic controller as a mechanical jam, triggering a protective motor stall.
