The life of a refrigerator shaded pole motor can vary due to a variety of factors, including the environment, frequency, maintenance, and so on. Generally, the life of a refrigerator shaded pole motor can range from several years to more than ten years.

The following are some factors that may affect the life of a refrigerator shaded pole motor:

1. Environment: When the motor is operated in a hot, humid or dusty environment, it may accelerate the wear and aging of the motor and shorten its life.

2. Frequency of use: The higher the frequency of use of the refrigerator shaded pole motor, the longer it works, so the life may be shortened accordingly.

3. Maintenance: Regular maintenance can extend the life of the motor. For example, keeping the motor clean and lubricating the bearings regularly can reduce friction and wear.

4. Quality and manufacturing process: The quality and manufacturing process of the motor will also affect its life production. High-quality motors usually have better durability and reliability, and may be relatively longer.

It should be noted that the above is only an estimate in general, and the actual motor life may vary depending on the brand, model and usage. If the motor makes abnormal noise, overheats or has other faults, it is recommended to contact professional maintenance personnel for inspection and repair in time.
