Refrigerator has two components say example 1. Compressor 2. Switch both are cover under warranty.
It means both components must be serialized materials. If the serialized it can be trackable by its serial number.
It doesn't make sense to me that without having any such records, how system will identify whether the component belongs to our company or some third party spare parts.
I'm in a opinion that, you must get the clear requirement from user on the above process.
